Screwdriver Bits 1/4" x 50 mm, S5.5 mm, 50 pcs YATO YT-7843
Professional S2 steel screwdriver bits supplied in a pack of 50. The 1/4" hex shank is compatible with most cordless screwdrivers and magnetic bit holders. The 50 mm length provides access to recessed screws.
Technical characteristics of the screwdriver bits
S2 steel - enhanced torsional strength
The S2 material (chrome-vanadium tool steel) has a hardness of 58-62 HRC, which translates into resistance to deformation when working with high torques. This steel contains chromium and vanadium additives that increase wear resistance and prevent the bit from cracking under load.
1/4" hex shank - the universal standard
The 1/4 inch (6.35 mm) hexagonal shank is the most popular standard in power tools and hand tools. It is compatible with cordless screwdrivers, combi drills, magnetic bit holders and extension adaptors with the same fitting.
50 mm length - access to recessed screws
The extended bit allows work in deep assembly holes, electrical back boxes and other places where a standard 25 mm bit cannot reach. The 50 mm length is a compromise between reach and stability when guiding the screw.
Slotted S5.5 mm profile - a wide range of applications
The 5.5 mm tip width suits screws with a 4.5-6.0 mm slot. The slotted profile is used in electrical installations (terminal blocks, sockets), furniture, window fittings and older household appliances and consumer electronics.

How to choose the right slotted bit?
The tip width of the bit should match the width of the screw slot - a bit that is too narrow may slip and damage the slot, while one that is too wide will not fit fully into it. A 5.5 mm bit fits screws with a 4.5-6.0 mm slot. If in doubt, it is better to choose a slightly narrower bit than one that is too wide.
Use and maintenance
S2 steel screwdriver bits retain their mechanical properties under intensive use, but they do require basic maintenance. After working in damp conditions, it is worth cleaning the bits and protecting them with a thin layer of oil, which prevents corrosion. During use, avoid exceeding the maximum torque of the screwdriver - excessive load can cause the tip to deform.
The 50-piece set provides a sufficient number of bits in case individual items wear out or are lost. In professional conditions, where bits are subject to intensive wear, such a reserve eliminates downtime caused by the lack of a suitable tool.
Tool compatibility
The 1/4" hex shank works with: cordless screwdrivers of all brands (Bosch, Makita, DeWalt, Milwaukee), combi drills with a quick-release chuck, magnetic bit holders, flexible extensions, right-angle adaptors and standard hand screwdriver handles with a 1/4" socket.
