The T8 Torx Star 1/4" hex bit 50mm (2 pack) is a compact screwdriver bit designed to drive T8 Torx (TX) screws. Its 50 mm overall length gives enough reach for recessed fixings while the standard 1/4" (6.35 mm) hex shank fits quick-change bit holders, ratchet adapters and power screwdrivers used in workshops and on-site jobs.

Each bit is manufactured from S2 tool steel and is heat treated to provide the torsional strength required for small Torx applications. The bits are finished with a black phosphate coating to improve corrosion resistance and reduce fretting between driver and bit. The 1/4" hex shank conforms to DIN 3126-C6.3 and ISO 1173 dimensional requirements for interchangeability with common 1/4" quick‑change systems. The Torx tip corresponds to the TX geometry used across industry for reduced cam‑out and accurate seating.

Typical applications for the T8 size include electronics assembly and repair, IT and telecom equipment, small domestic appliances, toys, camera and optical equipment, drones and precision mechanical assemblies. The T8 profile is widely used where small fasteners require repeatable drive engagement without damaging the screw head, such as laptop and mobile device servicing, instrumentation and electrical enclosures.

Key benefits of these bits are their compatibility with standard 1/4" hex drivers and bit holders, the corrosion protection offered by the black phosphate finish, and the strength and wear resistance afforded by S2 tool steel and heat treatment. The accurate Torx geometry reduces stripping and improves torque transfer compared with conventional slotted or Phillips tips, and the 50 mm length balances reach with control for delicate work.
