13 best heavy duty bar clamps

Heavy-duty bar clamps are essential tools in woodworking, metalworking, construction, and various DIY projects. They are designed to securely hold materials together, providing pressure and stability during tasks like gluing, welding, or assembly. Here's what you should know about heavy-duty bar clamps:

  1. Construction: Heavy-duty bar clamps consist of a long, straight metal bar, typically made of steel or aluminum, which serves as the main structural component. This bar is usually rectangular or I-shaped for strength and rigidity.

  2. Clamping Mechanism: At one end of the bar, there is a clamping mechanism. This typically includes a moveable jaw or head that can be adjusted along the length of the bar to accommodate different material sizes.

  3. Clamping Force: Heavy-duty bar clamps are known for their substantial clamping force. They can exert high pressure on the materials being held, ensuring a strong and secure grip.

  4. Throat Depth: The throat depth of a bar clamp is the maximum distance from the bar's edge to the clamping surface. It determines how far the clamp can reach into the material being held. Heavy-duty clamps often have a larger throat depth to accommodate thicker materials.

  5. Quick Release: Many modern heavy-duty bar clamps feature a quick-release mechanism, which allows for rapid adjustment and release of the clamp. This is useful for efficiency and convenience.

  6. Swivel Pads: Some heavy-duty bar clamps have swivel pads on the clamping jaws. These pads can conform to irregularly shaped workpieces, ensuring an even distribution of pressure and minimizing the risk of marring or damaging the material's surface.

  7. Multiple Sizes: Heavy-duty bar clamps come in various sizes, with longer bars providing greater reach and clamping capacity. Smaller clamps are suitable for smaller projects, while larger ones are ideal for larger materials.

  8. Durability: Given their "heavy-duty" designation, these clamps are built to withstand the rigors of demanding applications. They are typically made from high-quality materials and designed for long-lasting use.

  9. Applications: Heavy-duty bar clamps are versatile tools used in woodworking (e.g., joining boards), metalworking (e.g., welding), cabinetry, and construction (e.g., holding pieces together during framing).They are also handy for tasks like gluing, assembling furniture, and more.

  10. Safety: When using heavy-duty bar clamps, it's important to ensure that they are properly tightened and that the materials being clamped are secure. This prevents accidents and ensures accurate results.

In summary, heavy-duty bar clamps are robust and reliable tools used for clamping and securing materials during various projects. Their high clamping force and durability make them indispensable in professional workshops and for serious DIY enthusiasts who require dependable clamping solutions.

Question: Can the handle be turned a full 360° when the clamp foot/dogs are setting on the bench without being on the edge of the bench
Answer: there 2 24" clamps
Question: Can you please confirm a 42" tabletop glue-up with these clamps
Answer: There is no “made in” designations on the clamp, but the current parent company is Chinese, so a good bet would be that at least some of the components are manufactured in China. Of course that’s just my speculation. Nevertheless it’s a solid product by what was once a well regarded USA manufacturer.

User questions & answers

Question: Is the handle Rubber or wood? I just purchased the 6" version and the handle was rubber. I thought I wouldn't like it, but I did
Answer: Those I bought were wood. I have read that the rubber-handled clamps are being imported and that is also indicated by the old stamp "made in USA" missing from the bar. I also have some f-style clamps from Harbor Freight that were definitely imported and very inexpensive. Those have rubber handles, are more comfortable to use, and actually get decent reviews from woodworkers who are very critical of many imported clamps. The 12 in HD is a much heavier duty clamp and will apply great pressure without flexing. I believe that either the import clamp or wood handled clamp will serve you well, but the only way you will know what you get when you order is to get in touch with the vendor and specify what you want. There's still inventory out there of both types, at least of the medium-duty clamps. I bought 4 of the 6" clamps a couple of week ago and found both available.
Question: How heavy duty are these actually?? I've ruined over a dozen lowes brand clamps in the last year cause the threads strip out
Answer: The Jorgensen clamps are built like a brick-outhouse. The plastic style clamps you find at your local big box retailer are garbage by comparison. The Amazon "Best-Seller" is rated for 140-lbs, while the HD Jorgensen are rated for 1000 lbs clamping force. I own a bunch including a pair of light duty. Even on the light duty you won't strip the threads from over-tightening; the steel bar will just start to flex. They are virtually indestructible.
Question: Are these clamps reversible? can they be used as spreader clamps
Answer: No, but they are my favorite F-style clamps. Not only do they flex less than standard clamps, the wooden handles are larger in diameter than standard. I can put considerable more torque on them because they're easier to grip.
Question: Are these clamps sold thru amazon as of august 2015, still made in usa
Answer: Depends which vendor you purchase these from. We have these made in USA, so if you order from MHS, Inc - please make sure to email us with the order number to specify you want USA ones. Thank you!

PONY 50 Pipe Clamp, Fixture for 3/4-Inch Black Pipe

Pony Jorgensen

Based on 789 reviews Check latest price

Product description

PONY 50 Clamp Fixture for ¾ Inch Black Pipe is America’s most popular, most widely-used clamp fixture design. It is ideal for metalworking, woodworking and frame assembly - in applications that range from do-it-yourself to industrial production. Mounts on any length 3/4” black pipe with both ends threaded (pipe not furnished). A PONY Clamp Fixture is one of the handiest tools in any shop. One set of PONY Clamp Fixtures can be used to make any number of different length bar clamps simply by using the fixtures on different lengths of pipe. Heavy-duty black pipe is recommended. No tools are required for assembly. Simply screw the head assembly onto the pipe threads at one end. Slide the tail-stop onto the pipe at the other end. Then apply the coil-spring stop to the pipe threads at the tail-stop end of the pipe to prevent the tail-stop from sliding off the pipe during adjustment away from the work being clamped. PONY Clamp Fixtures are interchangeable from one pipe length to another, so one set can serve several needs. (NOTE: Make sure that pipe lengths are at least 7” longer than work to be clamped.) PONY Clamp Fixtures feature the original Multiple-Disc-Clutch design which allows a secure hold at any point along the pipe; no slipping, no pipe crushing...just instant adjustment either toward or away from the work being held. The extended clutch discs are accessible above and below the pipe for easy release. Castings are malleable and/or ductile iron; orange and black baked-enamel finish. Screw is 5/8” diameter steel with special, smoothly cut Acme threads; hardened steel thrust bearing in sliding head prevents wear at point of screw; crank-type handle. Multiple-Disc-Clutches are plated hardened steel; 4 pieces per set. Clamping faces are approximately 1-3/4” square. One coil-spring stop is included with each clamp fixture and prevents tail-stop from sliding off pipe. PONY Clamp Fixtures are designed for long life. The Chicago based Pony Tools Inc. which was established in 1903 is the manufacturer of all PONY Clamp Fixtures. The PONY 50 Clamp Fixtures are made with U.S. and foreign parts in our Chicago factory.

The best ideas are often the simplest, which explains why Jorgenson is well known among woodworkers as the maker of some of the best clamps available, and their 3/4-inch steel bar clamp is no exception. No shop can have too many of these. They offer a basic, reliable design--featuring a crank handle, no holes, no rivets, and no notches--that leaves little room for improvement. These clamps are great for a huge variety of jobs, can be used on any length of pipe your task requires, and can be relied on to keep their grip without loosening up or slipping. Removing the clamps when the job is done is quick and easy every time. Sure, some may say that a clamp is a clamp, and to some extent that's true. But with so many brands on the market, there's a reason it's so hard to find a shop that's not full of Jorgenson clamps. If you're looking for reliable clamps at a price that allows you to buy as many as you need, Jorgensen clamps are tough to beat. --Brian Trinen

User questions & answers

Question: Does the clamp face have holes in it. I need to mount a soft surface to the face so it does not damage my item
Answer: No, but these cushioned pads slip right on and stay on quite well. www.amazon.com/Adjustable-Clamp-7456-Cushion-4-Pack/dp/B0000224CC/ref=pd_bxgy_hi_text_y
Question: Do its work with galvanized pipe
Answer: "It does" work with galvanized pipe"."
Question: Does the pipe really have to be 7 inches longer than work? I'm curious because the clamp itself (both parts) is only 4 1/2 " wide
Answer: On a 24 inch pipe I measured 19 1/2 inches of opening on the clamps so the pipe only needs to be 4 1/2 inches longer than the item you're clamping.
Question: Do you need threaded pipe for these clamps
Answer: Yes, 3/4 threaded black pipe at most major home stores (which is threaded at both ends). The black handle part is the fine clamp adjustment and threads on to the black pipe, while the opposing clamp face slides on with a friction-fit adjustment for larger work pieces.

User questions & answers

Question: Are other buyers getting lesser rated irwin clamps instead of hd clamps they ordered
Answer: From the center of the screw to bar is 4 3/4". The distance between the two jaw pads is 12". These clamps work extremely well!
Question: clamp/spread changer is this the old (screw) or new version? shows both in the pictures
Answer: I guess the obvious answer is that it is determined by how strong you are. That is, how tight can you make it physically. I will tell you that I'm a woodworker and I've got a full set of these F-clamps and use them everyday. I've never had anything I've clamped down or together has ever come loose. Good clamps. As good as Bessey clamps, but cost less.
Question: Can it be used to push? Or open
Answer: No it does not spread. It is a great clamp though.
Question: Do these come with the little or big pads
Answer: Much too heavy to be aluminum.
