Apex 170-5/16B Torq-set Power Screwdriver Bit 1/4 in Hex

Product Description

The APEX 170-5/16B is a Torq-Set power screwdriver bit designed for use with 1/4 inch hex drive power tools and impact drivers. It features a 5/16 Torq-Set specialty point and measures 1.25 inches in overall length. The Torq-Set drive form provides positive engagement under load, reducing cam-out during high-torque fastening operations. This bit is suited for assembly and maintenance work in commercial and industrial environments where Torq-Set fasteners are specified, including aerospace, defense, and heavy equipment applications. It is installed and used by mechanics, technicians, and tradespeople who encounter Torq-Set fastener patterns in the field.

The 170-5/16B fits standard 1/4 inch hex quick-change bit holders and compatible power screwdrivers. The 5/16 Torq-Set point is intended for fasteners requiring a Torq-Set driver, which are commonly found in military and commercial equipment assemblies. The compact 1.25 inch overall length makes it practical for use in confined spaces where a longer bit would be difficult to maneuver.

Installation Notes

Insert the 1/4 inch hex shank fully into the bit holder before use to ensure secure seating. Confirm the Torq-Set point size matches the fastener recess before applying torque to avoid fastener or bit damage. Ensure the power tool is powered down and the trigger is locked out before changing bits. Use appropriate personal protective equipment when operating power screwdrivers.
