## Long description

Irwin Screwdriver Bit Torx T40 with a 1/4" (6.35 mm) hex shank and 25 mm working length is built for standard Torx screw engagement in both manual and powered drivers that accept 1/4" bits.

The 1/4" hex shank provides universal compatibility with bit holders, impact drivers and hand-held screwdrivers that accept 6.35 mm bits. Its 25 mm working length balances reach and control for typical fastening operations while remaining compact for use in confined spaces.

Key specifications
Bit type: Torx T40
Shank size: 1/4" (6.35 mm) hex
Working length: 25 mm
Material: hardened steel (manufacturer standard for bits)
Compatibility: fits 1/4" bit holders, driver sets and powered drivers
How to use
Insert the 1/4" hex shank into the bit holder or chuck of a compatible manual or powered driver until it seats securely. Align the Torx T40 tip with the screw head and apply steady axial pressure while driving to maintain engagement and minimize slipping. Use appropriate speed and torque settings on powered drivers to avoid over-torquing small fasteners; for manual driving, use a compatible bit holder or screwdriver handle to improve control.
Usage recommendations
Inspect the bit tip before use and replace if visibly worn or damaged to prevent screw head damage. Select a driver with adjustable torque or use a torque-limiting accessory when working with delicate components. Store bits in a dry container to reduce corrosion and preserve fit accuracy.
