Screwdriver Bits 1/4" x 50 mm Torx T15 YATO YT-7855 – pack of 50
A set of professional screwdriver bits with a 1/4" hex shank in Torx T15 profile. Made from S2 steel, designed for intensive work with electric and cordless screwdrivers.
Torx T15 screwdriver bits – key features
Torx T15 profile – precision and safety
The six-point star Torx profile provides a larger contact area with the screw than standard profiles. Size T15 corresponds to screws with a socket approximately 3.27 mm in diameter, used in electronics, household appliances and precision assembly work. This system minimises the risk of slipping and damaging the screw head.
S2 steel – a material for professionals
S2 tool steel (silicon-molybdenum steel) is characterised by a hardness of 58-62 HRC and high resistance to impact and twisting. Compared with standard chrome vanadium (CrV) steel, S2 steel copes better with dynamic loads when working with impact drivers, which extends the service life of the bits.
50 mm length – versatile use
50 mm bits strike a balance between compactness and access to recessed assembly points. This length works well in most workshop and construction applications, allowing work in fixing holes and on screws set deeper in the material.
1/4" shank – the professional standard
The 1/4" (6.35 mm) hex shank is the most common standard in power tools and hand tools. It ensures compatibility with cordless screwdrivers, drill drivers, magnetic bit holders and hand screwdrivers with interchangeable bits.

How to check compatibility with your tool
Make sure that the screwdriver or bit holder has a 1/4" quick-release chuck (marked "1/4 inch hex" or "6.35 mm"). Most modern cordless screwdrivers use this standard. For drills with a three-jaw drill chuck, a 1/4" hex shank adapter is required.
Use and maintenance
Torx T15 bits should be matched precisely to the screw socket size – play or a poor fit leads to faster wear of both the bit and the screw. Before starting work, it is worth checking the condition of the tip – rounded or chipped star points need to be replaced.
When working with a cordless screwdriver, the correct torque setting should be selected to avoid overloading the bit. For heavily tightened or rusted screws, it is worth applying a penetrating oil before starting to undo them.
After finishing work, the bits should be cleaned of dust and swarf. Storing them in a dry place prevents corrosion. The pack of 50 provides a reserve in case individual items wear out or are lost when working on site.
