Socket Bit 1/4" Hex 13 mm Hartsson 17A113Z

Hartsson 17A113Z is a 1/4" drive socket bit with a 13 mm hex profile, made for use with ratchets, bit holders and compact hand drivers. The 6-point hex design ensures secure engagement with fasteners and helps reduce rounding, making the bit suitable for routine mechanical assembly, maintenance and repair tasks where a compact 1/4" drive and 13 mm socket are required.

Advantages

The 6-point hex profile delivers firm contact with bolt heads and nuts, minimising slippage and wear on fasteners. Its 1/4" square drive format is compatible with a wide range of ratchets, extensions and bit holders, enabling use in confined spaces and on lightweight tools. The compact length and solid construction provide reliable torque transfer for typical workshop and field applications.

Suitable for

• General mechanical assembly and disassembly
• Routine maintenance and repair of machinery and equipment
• Tight spaces where a compact 1/4" drive accessory is needed
• Use with bit holders, compact drivers and ratchet handles

Key specifications

• Drive type: 1/4" square drive
• Bit profile: 6-point (hex)
• Working size: 13 mm
• Compatibility: designed for ratchets, bit holders and compact hand drivers
• Typical applications: assembly, maintenance, repair

How to use

Insert the 1/4" square drive end of the socket bit into a compatible ratchet, bit holder or compact driver until it seats securely. Align the 13 mm hex end with the fastener and apply steady torque, keeping the tool axis true to the fastener to avoid rounding. For high-torque applications, use a ratchet or driver matched to the required torque rating and avoid excessive force beyond the bit's intended use. Remove the bit by pulling it from the holder when work is complete.

Usage recommendations

Inspect fasteners and the bit before use; replace the bit if the hex edges show significant wear or rounding. Use the socket bit with tools appropriate to the required torque, and store in a dry place to prevent corrosion.
