Screwdriver bits GRAPHITE HEX 4 x 25 mm set of 2 (57H968)

Set of two GRAPHITE HEX screwdriver bits, size 4 x 25 mm. These bits provide a 4 mm hex profile and a 25 mm working length, designed to fit standard bit holders and interchangeable screwdrivers. The pack contains two identical bits intended for medium-depth fastening tasks in assembly, maintenance and repair where HEX 4 fasteners are used.

Advantages

GRAPHITE HEX bits are manufactured to deliver consistent fit with HEX 4 fasteners, reducing cam-out and wear during repeated use. The 25 mm length balances access and control, allowing work in slightly recessed screw positions while maintaining a stable drive. Supplied as a pair, the set provides a spare bit for uninterrupted work and convenient replacement when one bit becomes worn.

Suitable for

• General assembly of furniture and fixtures using HEX 4 screws
• Maintenance and repair of small machines and appliances
• Electromechanical and hobby projects that require a 4 mm hex driver
• Use with interchangeable screwdrivers, bit holders and compact power drivers

Key specifications

• Bit profile: hex (HEX) 4 mm
• Working length: 25 mm
• Quantity in set: 2 bits
• Compatibility: standard 1/4" hex bit holders and interchangeable screwdriver systems
• Intended use: manual and powered fastening tasks of medium depth

How to use

Select an appropriate bit holder or interchangeable screwdriver compatible with 1/4" hex bits, insert the GRAPHITE HEX 4 x 25 mm bit firmly into the holder, and engage the bit with the HEX 4 fastener. Apply steady torque, keeping the bit aligned with the screw axis to avoid slippage. For powered drivers, use controlled speed and torque settings suited to the fastener and material to prevent damage to the bit or workpiece.

Usage recommendations

Keep bits clean and inspect tips for wear before use; replace worn bits to maintain reliable engagement and prevent fastener rounding. Store the set in a dry place and use the spare bit to minimize downtime during repetitive tasks.
