14 best calibration standard rods
Calibration standard rods are precision instruments used in calibration, testing, measurement, and industrial applications.They are designed to serve as reference standards to ensure the accuracy and reliability of various measuring devices and equipment. Here is some information about calibration standard rods:
Purpose: Calibration standard rods are used to verify and calibrate the accuracy of measuring instruments such as micrometers, calipers, depth gauges, and other length measurement tools. They help ensure that these instruments provide accurate and consistent readings.
Design: Calibration standard rods are typically made from high-quality materials known for their dimensional stability and durability, such as stainless steel or tungsten carbide. They are precisely manufactured to have a known and certified length, diameter, and other critical dimensions.
Variety: These rods come in various lengths, diameters, and shapes to suit different calibration and measurement needs. Some may be cylindrical, while others may have flat ends for specific applications.
Certification: Calibration standard rods are rigorously calibrated and certified by accredited calibration laboratories to meet established standards, such as those set by the National Institute of Standards and Technology (NIST) in the United States or similar organizations in other countries.
Calibration Process: To use calibration standard rods, technicians or metrologists compare the measurements taken by their instruments against the known and certified dimensions of the rods. Any discrepancies are used to adjust and calibrate the instruments for accurate readings.
Applications: Calibration standard rods are essential in industries where precise measurements are critical, including manufacturing, aerospace, automotive, engineering, and quality control.
Traceability: To maintain traceability and ensure the reliability of measurements, calibration standard rods are periodically recalibrated to confirm their accuracy.
Storage and Handling: Proper storage and handling of calibration standard rods are crucial to preserving their accuracy. They are typically stored in protective cases or environments that minimize the risk of damage or contamination.
Maintenance: Regular maintenance and care are necessary to ensure the longevity and accuracy of calibration standard rods. This includes cleaning, handling with care, and protecting them from environmental factors that could affect their dimensions.
Calibration standard rods play a vital role in maintaining the accuracy and consistency of measurement tools, contributing to the quality and reliability of products and processes in various industrial and scientific fields.

The FAT Wrench is a perfect complement to the Deluxe Gunsmithing Screwdriver Sets. Together, they can ensure accurate tightening of most every screw on any gun in your collection.
- Accuracy: +/- 2 inch/pounds up to 40 inch/pounds; 40 – 65 is +/- 5%
- Ease of use: Apply, repeatable, accurate torque settings to scope rings, guard screws, windage screws and base screws, which aids in accuracy and decreases the opportunity for problems in the field
- Reliable: Torque adjustment range from 10 inch/pounds to 65 inch/pounds

- Includes: 10 bits (hex to square adapter, #10 flat blade, #32 flat blade, #11 flat blade, 5/32 hex, 7/64 hex, 3/32 hex, T20 torx, T15 torx and Leupold specialty flat blade), ¼” socket and a convenient plastic storage case
User questions & answers
| Question: | What are the sizes of the bits |
| Answer: | Amber,There are only a few bits in the set, including some uncommon bits that are not included in most sets of 1/4" bits.Between the bits in the set and other 1/4" bits that I have (also readily available online or in stores) I have never had any problem matching a bit to a screw.It is a great value and would have saved me much more money than its cost, if I had bought it before my first attempt to tighten or re-mount any scope.V |
| Question: | How many pounds for mini14 gas block screws |
| Answer: | 30 inch-pounds. They may be staked, so you may need to get replacement screws. Also important to use a feeler gauge to make sure gap is even on both sides, and Blue Locktite on the screws. |
| Question: | May I assume that this is a 1/4" drive |
| Answer: | It comes with a 1/4 inch drive adapter. |
| Question: | Anyone else find it nearly impossible to pull back on the adjustment part (bottom of the handle)? Maybe mine is defective |
| Answer: | Thank you all for your input on this!! I was struggling between this and a regular torque wrench, which is half the price, goes from 20 to 200 on adjustment, and is only 10" long!! Add a 1/4" socket to it, and use any bit you would like!! Easy to adjust it, and I'm sure I might need more that 65 in. # setting one of these days!!! Really thanks for taking the time to let people know these quirks!!! |

Firearms Accurizing Torque Wrench
The Wheeler Engineering F.A.T. Wrench is a hand driven, click/clutch system torque wrench that is very useful in apply the necessary torque to most firearms and firearm accessory fasteners. The F.A.T. Wrench features an ergonomic handle, a standard 1/4" hex drive tip, and can be used to apply torque from 10 to 65 in-lbs at 5 in-lbs increments. Common uses include; but are not limited to; instillation of scope rings and base screws, action screws and trigger guard screws. With proper care and use, the F.A.T. Wrench will provide you with a lifetime of reliable service. Package includes 9 bits and a square drive adapter.
-The F.A.T. Wrench is used like a screwdriver; it is not a ratcheting device.
-Leaving the F.A.T. Wrench adjusted at a high torque setting for extended periods of time may damage the internal mechanisms, resulting in inaccurate torque adjustments. ALWAYS ADJUST THE F.A.T. WRENCH TO THE LOWEST TORQUE SETTINGS AFTER EACH USE.
-Adjusting the F.A.T. Wrench beyond the torque wrench setting of 65 in-lbs may damage the internal mechanisms, resulting in inaccurate torque adjustments.
-The F.A.T. Wrench is compatible with all the bits contained in the Wheeler Engineering 89 piece Screwdriver Set.
-The F.A.T. Wrench is designed for +/- 2 in-lbs accuracy up to 40 in-lbs, +/- 5% over 40 in-lbs.
-The F.A.T. Wrench can be used to apply torque to any fastener; it is not limited to firearms and firearm accessories.
-Always protect the area surrounding screw heads with masking tape to prevent marring of metal and wood finished - just in case a bit slips out of the screw head while tightening.
-Small, inexpensive screws can be damaged with high torque settings. Be sure to comply with recommended settings.
-Small bits can be damaged with high torque settings. Replacement bits are available.
What do I need a Tourque Wrench?
Adjusting screws on gun actions, scope bases ans scopre rings can not only prevent damage to your gun but can greatly increase accuracy.
What torque should I adjust my fasteners to?
Always refer to manufacturesr specs but we recommend:
Base Screws 30 inch-lbs
Ring Screws (aluminum) 10 -15 inch-lbs
Ring Screws (Steel) 15-20 inch-lbs
Windage Screws 30-40 inch-lbs
Guard Screws
(with bedding pillars) 65 inch-lbs
(no bedding pillars) 40 inch-lbs
*note: middle guard screw should not be torqued
Will bits from my Wheeler Engineering Screwdriver Set fit?
Yes. The bits included in the Wheeler 89pc set and 72pc set are designed to work perfectly with the FAT Wrench.
Storage Tip for FAT Wrench.
Never leave the Fat Wrench adjusted to high torque settings for extended periods of time. After each use adjust the torque to the lowest setting prior to storage. This will releive the tension from the internal mechanisms and ensure maximum accuracy over time.
