The Buyer’s Guide
Expert firearms specialists or enthusiasts who like to repair handguns and rifles often need special skills of a gunsmith to handle such delicate things. Also, they have to be familiar with basic torque wrenches. In the following review, I’d like to cover a few useful tools for this purpose.
A gunsmithing wrench is a special kind of tool that can secure a rifle scope when you are applying the proper torque to scope mounts, rings, and screws. You won’t be able to fasten the action screws and bolts without an accurate torque wrench so make sure to buy one. I strongly recommend reading the manufacturer’s specs when making a choice.
Materials and design
It is extremely important to double-check the quality of materials and design before investing in any gunsmithing torque wrench. All parts must be made of metal. Just forget about cheap plastic torque wrenches – they are not worthy of your money. The reputable manufacturer should provide a warranty for its products. It is better to choose the wrenches with a lifetime or replacement warranty.
If you have such an opportunity, hold the wrench. The grip should be comfy and it mustn’t slip even if your hands are covered in gun oil.
As for the design, it is more preferable when the ratchet head can move and measure torque in both directions – counter-clockwise and clockwise. Check if the torque wrench has the “bi-directional” label.
Also, consider investing in a special gunsmithing screwdriver kit with different head attachments for basic torque wrenches. It can be extremely helpful if you use rifles with different scopes.
It is hard to underestimate the importance of using an accurate and pre-calibrated torque wrench when tightening the screws on your riflescope. If you seek maximum accuracy, consider using digital gadgets that show the measurement value in a different system. Check a few digital torque wrenches mentioned earlier. Slipper wrenches may also become a good choice at this point.
The price of gunsmith torque wrench may vary drastically. But it is wiser to skip the cheapest tools made of non-durable materials. Pricey wrenches are not more accurate than basic (and more affordable) tools but they can definitely offer more extra features. For instance, expensive (up to $100) digital wrenches typically come with a few adjustment ranges, a few preset modes, an advanced alert system, greater calibrations and more durable all-steel construction.
This guide covers the top-notch wrenches with various price tags. Consider what options you need and then choose the best wrench in its price segment.

Torque Wrenches for Gunsmithing FAQ
What type of torque wrench is most accurate?
Torque wrenches have long been one of the most frequently utilized instruments. There isn’t a single workshop that doesn’t have at least one or two torque wrenches, in addition to a spanner and socket kit. In conclusion, a torque wrench is a tool that helps the consumer to control the amount of force or torque added to a bolt when locking or loosening it.
The shown torque performance on most models has a precision tolerance. Any suppliers and styles, for example, have a tolerance of +/- 4%, +/- 2%, or even +/- 1%. The smaller the tolerance, the more reliable the reading would be, as long as the true reading is inside the defined + or percentage of tolerance.
Torque wrenches that are digital or electronic are thought to be the most precise. They offer a digital readout screen on which the torque cap can be programmed. A strain gauge connected to a torsion rod gives a notification to a transducer, which calculates the torque force per device and displays it with an LED reading.
The consumer will be alerted by LED lights as they are reaching the target torque setting and by an audible warning signal when the torque level has been hit. Some versions often have an internal computer chip that enables torque measurements to be stored and later downloaded to a database for archival purposes. This is indeed advantageous for certain auditing purposes. Over the past few years, the cost of electronic wrenches has decreased, making them even more economical and available to most car mechanics.
Consider that a torque wrench is a precise tool, so buy the finest one you can. Investing in a high-quality torque wrench, on the other hand, would seem to be the wisest decision since you will get a product that is reliable, durable, and likely to last a long time.
Do you need a torque wrench for ar15?
Although building your ideal rifle from the ground up isn’t complicated, there are some aspects of the AR-15 design that tangle people up. It is up to you to decide whether or not you require a wrench for your AR15 design.
Since the normal torque range is 30-80 ft-lbs, there’s no need. Tighten it by hand, then step on to the next gas tube hole, and you’ll be up past 30 foot-pounds in no time. However, a wrench would be required if the AR rifle’s barrel nut required a certain torque, such as 66.5 foot-pounds.
Tighten the barrel nut beyond 30 foot-pounds with a torque wrench before the nearest accessible notch in the barrel nut aligns with the opening in the upper receiver. Do not use more than 80 foot-pounds of force.
What is the best brand of torque wrench?
Here are several suggested wrenches for gunsmithing and maintenance work such as tire rotation, spark plug replacement, and cylinder head bolts, among other items. A few top-notch torque wrench brands you may rely on:
- Tekton (e.g. 24335 1/2 inch drive click torque wrench);
- Precision Instruments (e.g. PREC33FR250F ½-inch drive);
- EPAuto (e.g. 3/8 inch 10-80 foot-pound wrench);
- Venzo (the set of Allen keys);
- Pittsburgh Torque Wrench (e.g. pro reversible click type);
- Snap On;
Is it ok to loosen bolts with a torque wrench?
A torque wrench is a mechanism for tightening. This fragile and accurate tightening mechanism shouldn’t be used to undo/loosen any nuts or bolts. Treat your wrench with the same respect you will a measuring device.
Even if a bolt or nut has been torqued to design, it needs more torque to release it than it does to tighten it.
What can you use if you don’t have a torque wrench?
If you can’t spend $50 – $100 on a new torque wrench, there are a few alternatives you may use as a replacement:
- You may want to use a common wrench as well as a scale instead of a full-fledged torque wrench. It is possible to quantify the moment (or torque). T = F x a, where T represents the moment or torque (Nm, lbs-ft), F represents the applied force (N, lbs-ft), and a represents the wrench duration (m, ft);
- A long ratchet or a breaker bar would also do the job, but anything at least a foot long would be needed. If you’re dealing with foot-pounds, you’ll need a way to calculate the exact distance between the part and your arm, as well as a way to measure the amount of force applied. Use a scale and the above mentioned-formula;
How can you know how much torque you need?
To ensure that your firearm operates reliably and without cracking, you must understand how to quantify bolt tightening torque. A measurement error could cost tens of thousands of dollars, not to mention the time and resources needed to repair damaged machinery.
You may want to use this simple formula:
T (torque) = K x F x d
K stands for the coefficient of friction, d means the bolt diameter, F is the axial bolt force calculated in Newtons or pounds. T obviously means the Torque.
Take a simple example to figure out how to calculate the torque for a certain bolt or nut. Your K will be 0.2, which is a standard friction coefficient (without lubrication). The width of your bolt will be 0.5 meters, and the axial bolt power will be 11,175 pounds.
Fill in the blanks in the above-mentioned formula:
T = 0.2 * 11,175 * 0.5
T = 1,117.5 inch-pounds
Then divide by 12 to convert to foot-pounds. T = 1,117.5 / 12 = 93.125. This means the torque is 93 foot-pounds.
