Screwdriver bit GRAPHITE 56H508, 1/4" drive, 5 mm hex, 25 mm length, blister

GRAPHITE 56H508 is a 5 mm hex screwdriver bit with a 1/4" drive and a 25 mm working length, supplied in a blister pack. Made of S2 steel and designed for use with bit holders, ratchets and cordless drivers that accept 1/4" bits, this HEX5 bit is intended for fastening and loosening hex-head fasteners in assembly, maintenance and repair tasks. The bit weighs approximately 10 g and its working tip is machined to ensure a precise fit with fastener heads.

Advantages

The bit is manufactured from high-quality S2 steel, offering increased flexibility and enhanced resistance to mechanical damage. A torsion zone integrated into the design reduces transmitted peak forces under high torque, lowering the risk of breakage and extending service life. The accurately machined working tip ensures a secure engagement with hex fasteners, improving efficiency and reducing cam-out during use.

Suitable for

• Assembly of furniture and metal constructions with 5 mm hex fasteners
• Maintenance and repair tasks requiring a 1/4" drive 5 mm hex bit
• Use with manual bit holders, ratchet drivers and cordless/corded screwdrivers accepting 1/4" bits

How to use

Insert the 1/4" drive end of the GRAPHITE 56H508 bit into a compatible bit holder, ratchet or screwdriver chuck until it locks. Engage the 5 mm hex tip with the fastener head, ensuring full seating to avoid slipping. Apply controlled torque appropriate to the fastener and material; the torsion zone will absorb peak loads during heavy-duty fastening or loosening. After use, retract the bit and store it in its blister or in a suitable storage rack to protect the tip.

Usage recommendations

Use the bit with tools rated for the required torque and avoid exceeding the recommended torque for the fastener and material. Inspect the tip before use for wear or damage and replace the bit if deformation or excessive wear is visible. For impact driver applications, select bits specified for impact use; this bit's S2 construction and torsion zone are designed to increase durability under higher torque conditions.
