Borka Tools BTKST Standard Configuration Adjustable Torque Driver Kit

The Borka Tools BTKST Standard Configuration Adjustable Torque Driver Kit is an American-made precision instrument built to deliver repeatable, calibrated torque control for scope ring installation, base screws, action screws, red-dot mounts, and other critical firearm fastening tasks. Centered on the fully adjustable Borka Torque Driver (BTD1070-IP), the kit covers a working range of 10 to 70 inch-lbs with a tight +/- 4% calibration accuracy, so you can torque to spec rather than guess.

At the heart of the kit is a compact ratchet handle with a 1/4" hex (female) x 1/4" square drive (male) interface, accompanied by a set of adapters and an extension so the same driver works with both hex-bit and standard square-drive bit holders commonly found on firearms hardware. Everything is organized in a rugged Cordura nylon pouch measuring approximately 8 x 5.5 x 2 in, giving the entire kit a tidy total weight of just 1 lb 6 oz - small enough for a range bag or a gunsmith's bench drawer.

Whether you are lapping rings, bedding an action, or simply making sure a scope base goes on to manufacturer torque, the BTKST gives you the calibrated control to do the job right without stripping screws or cracking scope tubes.
