Screwdriver bit GRAPHITE 56H529, Torx Plus TX40, 1/4" drive, 50 mm length

GRAPHITE 56H529 is a Torx Plus TX40 screwdriver bit with a 1/4" drive and a 50 mm overall length. Manufactured from S2 tool steel and finished for a precise working tip, this bit is intended for use with screwdrivers and impact drivers in applications that require a short, robust Torx Plus TX40 insert. Supplied in a blister pack, the bit weighs approximately 24 g and is suitable for fastening and loosening Torx Plus TX40 screws in automotive, electronics and general assembly tasks.

Advantages

The bit is made of high-quality S2 steel, offering increased flexibility and resistance to mechanical damage. A dedicated torsion zone reduces the transmission of extreme torque peaks, decreasing the chance of breakage and extending service life. The working tip is machined to ensure accurate fit and consistent engagement with Torx Plus TX40 screw heads, minimizing cam-out and wear. The 1/4" drive and 50 mm length provide a balance between accessibility in confined spaces and stable tool handling.

Suitable for

• Automotive repair and maintenance tasks requiring Torx Plus TX40 fastening.
• Electronics assembly and disassembly where short, precise bits are needed.
• General industrial and workshop assembly requiring impact‑resistant bits.
• Use with manual screwdrivers and impact drivers with a 1/4" hex socket.

How to use

Insert the 1/4" drive end of the GRAPHITE 56H529 bit into a compatible screwdriver or impact driver chuck and ensure it is securely seated. Align the Torx Plus TX40 tip with the screw head and apply steady axial pressure while driving or removing the screw. For impact-driving applications, allow the tool's impulse action to engage the bit; the torsion zone will absorb torque peaks. Inspect the tip periodically for wear and replace the bit if the fit with screw heads becomes loose or damaged.

Usage recommendations

Use appropriate personal protective equipment and select the correct torque setting on power tools to avoid overloading the bit. Store the bit in its blister or a dedicated bit holder to protect the working tip and maintain fit accuracy. For consistent performance in heavy-duty applications, check the bit regularly and replace it when signs of deformation or excessive wear appear.
