This is a T6 Torx (star) 1/4" hex screwdriver bit, 25 mm overall length, intended for precision assembly and maintenance where small Torx fasteners are used. Its primary use is to drive and remove T6 (TX6) star-headed screws in electronics, small appliances, hobby models and precision engineering tasks where access is restricted and a short, accurate bit is required.

The bit is manufactured from S2 tool steel for improved torsional strength and wear resistance compared with generic carbon steels. The surface is finished with a black phosphate coating to give basic corrosion protection and reduced glare during use. The tip presents the six-lobe Torx profile (T6 size) and the shank is a 1/4" (6.35 mm) hex which conforms to DIN 3126 / ISO 1173 dimensions for quick‑change bits and standard bit holders. There are no threads on this product – it is a straight, driven bit designed for insertion into 1/4" hex chucks, bit holders, screwdriver handles and compatible power-tool adapters.

Typical applications include electronic repair and refurbishment, IT and telecoms equipment maintenance, laptop and mobile device servicing, small electrical assembly, model making, and precision mechanical work. Industries that commonly use T6 bits include electronics manufacturing and repair, aerospace component servicing at small scale, medical device maintenance and hobbyist/model engineering sectors where small Torx fasteners are specified by manufacturers.

Key benefits of this 25 mm bit are its compatibility with the ubiquitous 1/4" hex system found on most screwdriver handles and quick‑change chucks, the dimensional accuracy of the Torx tip which reduces cam‑out and fastener damage, and the enhanced strength from S2 tool steel for reliable lifetime under normal service loads. The black phosphate finish offers a degree of corrosion resistance and smoother insertion into tight fittings. Note that while S2 bits are robust for hand and powered screwdriver use, only bits specifically marked as impact‑rated should be used in impact drivers.

Duchy Fasteners stocks this T6 1/4" hex 25 mm bit individually and in assorted bit sets; other Torx sizes and lengths are available in single units and multi‑pack options to suit workshop and service requirements.
