Screwdriver Bits set GRAPHITE 57H977 T40 x 25 mm, 2 pieces

Set of two GRAPHITE screwdriver bits model 57H977, type T40 with a 25 mm length. These replaceable Torx T40 bits are made to fit standard bit holders and drivers for fastening and loosening T40 fasteners. The compact 25 mm length makes them suitable for use in confined spaces while remaining compatible with common power and manual bit drivers used in assembly, repair and maintenance tasks.

Advantages

The set contains two identical T40 bits, providing a spare or quick replacement during work. The 25 mm length balances accessibility in tight spots with secure seating in bit holders. Manufactured by GRAPHITE to standard bit dimensions, the tips are designed for reliable engagement with Torx T40 fasteners and straightforward interchangeability with common drivers.

Key specifications

• Type: Torx T40
• Length: 25 mm
• Quantity: 2 pieces
• Compatibility: standard 1/4" hex bit holders and drivers

How to use

Insert the T40 bit into a compatible 1/4" hex bit holder or directly into a driver chuck until it seats securely. Use appropriate torque settings on powered drivers to avoid over-tightening; with manual drivers, ensure the bit is fully engaged in the fastener before applying force. Replace bits as needed if signs of wear or rounding on the tip appear to maintain secure engagement with Torx fasteners.

Usage recommendations

When working with power drivers, set torque and speed to match the fastener and material to reduce wear. Keep spare bits like this two-piece set accessible to minimize downtime. Inspect tips regularly and replace when deformed or damaged to preserve fastener integrity.
