Hartsson 1/4" 11 mm hexagonal socket bit is a compact hand tool accessory designed for use with 1/4-inch drive ratchets, screwdrivers and bit holders. The six-point hex shape fits standard hex fasteners to deliver reliable torque transfer during assembly, maintenance and repair operations on machinery, furniture and automotive parts. As a spare part for professional and home toolkits, this 11 mm socket bit offers a straightforward solution when replacing worn bits or completing specialised fastener work.

Advantages

This 11 mm hexagonal socket bit provides a precise six-point engagement that reduces rounding of fastener heads and improves torque delivery. Its 1/4" drive interface ensures compatibility with a wide range of ratchets and bit holders, allowing quick exchange and flexible use. The compact size makes it easy to store in toolkits and carry to work sites, while the robust construction is intended for repeated use in assembly and repair tasks.

Suitable for

• Assembly and disassembly of furniture and fixtures
• Maintenance and repair of light machinery and equipment
• Automotive interior and light engine bay fastening tasks
• Professional and hobby toolkits requiring 11 mm hex drive

Key specifications

• Drive size: 1/4" (6.35 mm) standard drive interface
• Tip profile: 6-point (hexagonal) 11 mm
• Intended use: manual ratchet, screwdriver and bit holder compatibility
• Form factor: compact socket bit for insertion into bit holders or extension adapters

How to use

Insert the 1/4" drive end of the socket bit into a compatible ratchet, screwdriver or bit holder until it engages securely. Place the 11 mm hex tip over the fastener head and apply steady torque, ensuring the bit remains fully seated to avoid slippage. For access in recessed locations, use with a compatible extension or universal joint. After use, wipe the bit clean of debris and store it in a designated slot of a toolkit to prevent loss and damage.

Usage recommendations

Use with hand tools rated for the applied torque; avoid excessive force from power tools unless the bit is specifically rated for impact use. Select the correct 11 mm hex size to minimise wear on fastener heads and the bit itself. Regularly inspect the working tip for rounding or damage and replace the bit when wear is visible.
