Socket bit 1/4" AWTools short hex 4 mm Black Line

AWTools Socket bit 1/4" short hex 4 mm Black Line is a compact 1/4" drive bit with a 4 mm internal hex profile. It is part of the Black Line range and is intended for fastening and loosening hex-head screws and bolts where space is limited. The short length improves access in confined assemblies, repair tasks and maintenance work while remaining compatible with ratchets, bit holders and power drivers accepting 1/4" bits.

Advantages

The short design reduces leverage-related wobble and makes the bit easier to position in tight recesses. Hardened tip geometry and precision-machined hex profile ensure accurate fit on fasteners to minimise rounding. Its 1/4" drive compatibility provides straightforward use with a wide range of hand and powered tools. The Black Line finish offers basic surface protection against corrosion and wear during regular workshop use.

Suitable for

• Automotive assembly and repair in confined engine bay or interior spaces
• Electrical and electronic enclosures where clearance is limited
• Furniture assembly and maintenance with recessed hex fasteners
• General mechanical repair and maintenance in workshops

Key specifications

• Drive size: 1/4"
• Tip profile: internal hex (Allen) 4 mm
• Overall length: short/compact type for limited clearance
• Material: hardened tool steel with protective Black Line surface finish
• Compatibility: fits standard 1/4" bit holders, ratchets and drivers

How to use

Select a matching 1/4" holder or driver, insert the socket bit securely into the chuck or bit socket, then engage the bit with the hex-head screw or bolt. Apply steady, aligned torque and avoid excessive force to prevent fastener damage. For powered drivers, set an appropriate torque or clutch setting and use short bursts to control fastening. After use, wipe off debris and store the bit in a holder or toolbox to protect the cutting surfaces.

Usage recommendations

Use the AWTools 1/4" short hex 4 mm Black Line bit when working in restricted spaces where a standard-length bit cannot reach. Match bit size precisely to the fastener to reduce cam-out. For high-torque tasks, consider using a longer or impact-rated bit designed for heavy-duty drivers.
