Apex 273A-2 Torq-set Power Screwdriver Bit Size 2

Product Description

The APEX 273A-2 is a Torq-Set specialty power screwdriver bit designed for use with power screwdrivers and pneumatic or electric drive tools. It features a Number 2 Torq-Set point and a 0.25-inch drive size, with an overall length of 1-13/16 inches (46 mm). The Torq-Set profile is a cross-recess design that requires a matched driver to engage, making it common in aerospace and military-specification assemblies where cam-out resistance and precise torque control are required. Installation and removal of Torq-Set fasteners without the correct bit will damage the recess, so using the proper matched driver is essential.

This bit is suited for applications where Torq-Set fasteners are specified, including aerospace structures, military equipment, and specialty mechanical assemblies that require a tamper-resistant or torque-controlled fastening system. The compact 1-13/16-inch overall length fits standard power bit holders and inline screwdrivers. It is typically used by aviation mechanics, specialized assembly technicians, and maintenance professionals working on equipment with Torq-Set fastener specifications.

Installation Notes

This bit is intended for installation and removal of Torq-Set fasteners and should be used only with matching Torq-Set recesses to prevent fastener damage. Ensure the power driver is set to an appropriate torque range for the fastener specification before driving. Inspect the bit tip for wear before each use, as a worn Torq-Set profile will not seat fully and can strip the fastener recess. Follow all applicable equipment and workplace safety guidelines when operating power drive tools.
