Screwdriver Bit GRAPHITE 57H990 T40 x 50 mm Torx tip

GRAPHITE screwdriver bit 57H990 T40 x 50 mm Torx tip is a replacement driver tip designed for Torx T40 fasteners. With a 50 mm overall length, this steel bit fits common bit holders, ratchets and power screwdriver chucks to extend reach into recessed or hard-to-access screw locations. The Torx T40 profile ensures a standardized fit that reduces cam-out and provides consistent torque transfer for assembly, maintenance and repair tasks.

Advantages

This Torx bit offers a precise T40 geometry for reliable engagement with compatible fasteners and reduced slipping during use. The 50 mm length provides extra reach without sacrificing control when used with hand or powered drivers. Constructed from hardened steel, the bit is intended to withstand repeated insertions and torque application typical in workshop and field environments. Its standardized shank diameter enables compatibility with a wide range of bit holders and quick-change adapters.

Suitable for

• Fastening and removing Torx T40 screws in mechanical assembly
• Maintenance and repair of appliances, electronics housings and automotive components
• Accessing recessed screws in furniture and machinery where extra reach is needed

Key specifications

• Tip type: Torx T40
• Overall length: 50 mm
• Shank style: standard 1/4" hex-compatible shank for bit holders and chucks
• Material: hardened tool steel for wear resistance
• Finish: industrial finish suitable for workshop use

How to use

Insert the 1/4" hex shank into a compatible bit holder, ratchet adapter or power screwdriver chuck until it seats securely. Align the T40 tip with the screw head and apply steady axial pressure while turning to drive or remove the fastener. For powered tools, use controlled speed and torque settings to prevent damage to the screw head or surrounding material. Inspect the tip for wear before use and replace it if the Torx profile shows rounding or deformation.

Usage recommendations

Use the bit with appropriately rated drivers and avoid excessive torque beyond the specifications of the fastener. Keep the tip clean of debris and periodically check for wear. Store the bit in a protective holder to prevent damage and ensure accurate fit in future applications.
