This is a T8 Torx (TX) star bit with a 1/4" (6.35 mm) hex shank and a working length of 25 mm, designed for driving Torx-profile fasteners in precision and light‑duty assembly work. Its primary use is for manual and powered screwdrivers, quick‑change bit holders and general maintenance tasks where a compact, accurate Torx T8 tip is required.

The bit is manufactured from S2 tool steel and is heat treated to approximately 58–62 HRC for good wear resistance and torsional strength. The shank is the industry standard 1/4" hex, compatible with ISO/DIN quick‑change holders and most 1/4" chuck systems. The tip profile conforms to common Torx (TX) tolerances used across DIN/ISO/BS derived fastener specifications so it neatly engages T8 fasteners and reduces cam‑out. The surface finish is black phosphate providing basic corrosion resistance and improved lubricant retention; chrome or nickel plated variants are also available in some production runs for enhanced corrosion protection where required.

Typical applications for a T8 bit include small electronics assembly and repair, IT and server maintenance, appliance servicing, precision engineering, instrumentation and hobbyist model building. Torx T8 is commonly found on small components, connector housings and interior fastenings where a secure drive and repeatable torque are needed. Industries that commonly use this size include electronics manufacturing, telecommunications, laboratory equipment servicing and specialist engineering workshops.

Key benefits of this bit are its accurate Torx profile for reliable engagement with T8 fasteners, the strength and fatigue resistance provided by S2 steel and heat treatment, and the convenience of the 1/4" hex shank for rapid bit changes. The black phosphate finish gives a measure of corrosion resistance while maintaining a low profile for close‑tolerance work. For heavy impact work choose impact‑rated variants, but this bit is ideal for everyday hand and light power use.
