Precision Torque Limiters and Kits

Borka PTL062K for FN SCAR 16/17 rifles

Borka Tools PTL (Precision Torque Limiter) is based on design of a very compact, industrial grade torque limiting device, which is calibrated in accordance with related ISO-6789 procedure. PTL is correctly sized for the upper range of its limiting torque values, has heavy duty all metal construction and demonstrates high torque output precision (+/-4% as stated, but often no more than +/-2% actual), along with perfect consistency over many years of usage. Mountz Inc., one of the premier torque tool companies in the world, also offers similar PTLs for industrial applications. It is a testament to high quality construction, accuracy and consistency of this tool.

Below is a video about PTL-062K kit for FNH-SCAR 16/17 barrel change, which can be also beneficial to watch as a generic visual guide for any PTL based kits.


Borka PTL certificate of CalibrationDepending upon availability, each PTL has either an individual serial number, laser marked I.D. note and certificate of calibration as shown on the left, or PTL has a very durable polymer based I.D./Calibration label attached directly to the PTL body without any separate cerificate of calibration. PTL is preset to specific limiting torque value in CW and CCW directions of rotation. It is calibrated in CW rotation and is not user adjustable to other torque values. Torque preset in CCW rotation serves as its purpose to prevent any damage to torque limiting mechanism, if PTL is also used to loosen the fasteners. As a general rule, it is advisable not to use torque tools to loosen fasteners, only to tighten them. However, Borka Tools PTL, which limits torque in CW and CCW rotations, may be used to loosen fasteners without any negative consequences, but only if fasteners were originally tightened with the same PTL (1), and if fasteners are not seized due to various factors (2), which may take place over extended periods of time. Otherwise, just use included ratchet handle to loosen the fasteners. See PTL user guide for more details and specific instructions.

Borka Tools Precision torque limiter assemblyPTL based torque tool consists of torque limiter, which is preset to specific tightening torque value, custom made 4.5" long ratchet drive handle with both 3/8" square (M) and 1/4" hex (F) socket drive ends, and typically, comes with either standard size 1/4" hex shank screwdriver bit or 1/4" square drive adapter. Torque limiter has 3/8" square (F) drive input and 1/4" hex (F) socket output. Ratchet drive handle, which is rated up to 250 inch-lbs. of torque, can be very easily and quickly connected to and disconnected from the torque limiter, and can be used as a conventional ratchet driver by itself, both in CW and CCW rotation. Torque limiter can be also driven by any suitable handle with standard 3/8" square (M) drive. Typically, torque limiter and ratchet drive handle are shipped as two separate components of the torque tool, to make tool package as compact as possible.

Warning: Never use PTL with relatively high RPM power drivers. This will cause both accelerated and excessive wear of the torque limiting mechanism, will degrade PTL accuracy, and may cause permanent damage. Use PTL as a hand driven tool only. 

An example of Borka Tools PTL kitKit with two PTLs is packaged in our standard plastic case with fitted hard rubber foam insert. Case insert can hold two PTLs, ratchet drive handle, 1/2" hex socket, two 1/4" adapters and up to four screwdriver bits. Our single PTL kit is packaged in 5" long x 1.5" wide black color nylon pouch, or, as a customer selectable option, in our standard case, but with universal soft foam flat insert. This packaging option provides certain advantage of an extra space for some additional small tools and parts.

Contact us by e-mail for custom configurations of PTL based kits with two (or even more) included PTLs and set of accessories. Scroll down this page to see more details related to custom PTL based kits. We have PTLs in stock with various torque settings, which include 15, 20, 25, 40, 45, 49, 50, 53, 55, 60, 62, 65, 70 and 80 inch-lbs. If we do not have PTL with limiting torque preset, which you are interested in, we may be able, for an extra $10, to recalibrate one of the available PTLs to meet your requirements in the range between 15 inch-lbs. and 75 inch-lbs.

If, in addition to purchasing our PTL based kit(s), you may be interested in high quality modular cleaning rod (MCR) kit, which is custom made for Borka Tools by Pro-Shot Products, check it out here at the bottom of the page and then e-mail to us for a quote.

If you would like to add more of the torque limiters to a kit, which already includes at least one of them, you can purchase 2nd torque limiter for $33.00 and the 3rd torque limiter for $30.00. Additional torque limiter(s) will be packaged in plastic tool tube(s) and will be shipped along with the primary kit as a "single kit". You can also purchase a separate torque limiter for $35.00, as opposed to buying a kit, without ratchet drive handle and other kit accessories. To use this offer, contact us by e-mail.

To place an order for a custom PTL kit, please first contact us by e-mail or phone, and let us know your requirements with consideration to available options shown below:

If your specific application requires 3 or more tightening torque settings (requires use of 3 or more torque limiters), we suggest that you take a look at one of our adjustable torque driver kits instead of PTL based kit. As an example, price of kit with 3 PTLs is comparable to the price of ATD-SBK, which includes better variety of accessories and provides a lot wider range of available torque settings. Relative value comparison is the reason for our decision to offer standard PTL based kits with either 1 or 2 torque limiters only. If you need help with making a cost effective decision, feel free to call.
