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. All PTLs incorporate an adjustment set screw, which makes it technically possible to pre-set PTL exactly to the desired limiting torque value and to re-calibrate torque limiter, if necessary. This feature gives PTL an important advantage in comparison to some other torque limiters, which do not provide any means for external limiting torque adjustment or re-calibration after certain number of cycles.

Below is 2013 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. Take note that since January of 2018, this single PTL kit packaging method has been changed.

  

Depending upon stock availability, each PTL has either a laser marked I.D. note on its body and separate certificate of calibration, 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 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 PTL, which limits torque in CW and CCW rotations, may be used to loosen fasteners without 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 drive handle to loosen the fasteners. See PTL user guide for more information.

Borka Tools Precision torque limiter assemblyPTL based torque tool kit consists of torque limiter, which is preset to specific limiting 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 is often supplied with either standard 1" long or custom length 1/4" hex shank screwdriver bit. This torque limiter has 3/8" square (F) drive input and 1/4" hex (F) socket output. Compact ratchet drive handle, which is rated up to 250 inch-lbs. of torque, can be quickly connected to and disconnected from the torque limiter, and can be then used as just a conventional ratchet driver by itself, both in CW and CCW rotation. Torque limiter may be also driven by any suitable handle with standard 3/8" square (M) drive.

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 result in permanent damage. Use PTL as a hand driven tool only. 

An example of Borka Tools PTL kitKit with two PTLs is packaged in Borka 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. As an example, Borka Tools PTL1565K kit is shown on the left. As of January 26th, kit with single PTL is packaged with use of a durable PVC tool tube and reclosable poly bag, instead of previously offered nylon pouch. Change in kit packaging method resulted in 8% ($3) price reduction for a single PTL kit.

Contact us by e-mail for custom configurations of PTL based kits with one, two or even more included PTLs and a set of accessories. Scroll down this page to see more details related to custom PTL based kits. We offer PTLs with various torque settings, including 15, 18, 20, 25, 30, 35, 40, 45, 49, 50, 53, 55, 60, 62, 65, 68, 70 and 80 inch-lbs.
If PTL with desired limiting torque preset is not listed above, we may be able, for an extra $5, to recalibrate stock PTL(s) to meet your requirements in the range between 15 inch-lbs. and 80 inch-lbs., with a limiting torque preset accuracy of +/- 4%.

Please take note that we do not ship PTL based kits to international retail customers.

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

To place an order for your custom PTL kit, send us an e-mail with your requirements.
As an example, two of the most common custom kit configurations are shown below:

PTL with long bit
 

 
Suggested application:
 Your chassis based precision rifle,
 for application of specific tightening
 torque value with use of a long bit 
 Custom 1 PTL kit  includes:
 1. T1 torque limiter of your choice
 2. Ratchet drive handle
 3. Your choice of either Borka Tools
     3/16" ball-end hex 4" long bit, or

 2. T2 torque limiter of your choice
 3. Ratchet drive handle

 Prior to purchasing your
 custom kit, e-mail to specify
 T1 and T2 preset torque
 values, along with bit sizes

  

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.
