Hexagon Wrench Sets & Ballpoint Hex Key Sets — Unbrako

Unbrako Hexagon Wrench Sets are precision-manufactured L-shaped Allen keys designed to deliver the exact fit and torque transfer that Unbrako socket screws demand. Available in metric sizes from 1.5mm to 32mm and inch sizes from 1/16" to 3/4", these wrenches are manufactured from chrome vanadium steel with a black finish for corrosion resistance and sure grip. The precise hexagon profile matches Unbrako socket dimensions exactly, minimizing cam-out and socket wear even under repeated high-torque use. For applications requiring angled access, Unbrako Ballpoint Hexagon Wrench Sets feature a radiused ball end that allows engagement at angles up to 25 degrees off-axis — essential for reaching fasteners in confined spaces, recessed pockets, or obstructed locations. Both standard L-shape and ballpoint sets are available individually or in holder sets for workshop organization. Shri Narayan Machinery LLP in Noida supplies the complete Unbrako wrench range as individual keys and complete sets for maintenance and assembly operations.
