Socket bit AWTools 1/2" hex impact 21 mm long Black Line

AWTools 1/2" hex impact socket bit 21 mm long Black Line is a long-reach, impact-rated hex socket designed for use with 1/2" drive impact wrenches and rattle guns. Constructed for heavy-duty fastening tasks, this socket bit provides extended access to recessed or hard-to-reach hex fasteners while maintaining the torsional strength required in impact applications. The Black Line finish helps resist surface wear and provides a uniform appearance for workshop use.

Advantages

The long 21 mm hex size gives greater reach than standard-length sockets, enabling access into deeper recesses and around obstructions. Manufactured for impact use, the socket bit is heat-treated to withstand repeated high-torque impulses and reduce the risk of cracking. Compatibility with 1/2" drive impact tools ensures reliable power transfer and stable seating on hex fasteners, improving efficiency and reducing fastener rounding.

Suitable for

• Automotive repair and maintenance where extended reach is needed
• Industrial assembly and machinery maintenance with recessed hex fasteners
• Construction and installation tasks using impact wrenches
• Workshops and service garages requiring durable impact-rated sockets

Key specifications

• Drive size: 1/2 inch
• Head type: 6-point hex (21 mm)
• Overall form: long / extended length socket bit
• Intended use: impact applications with impact wrenches and rattle guns
• Finish: Black Line surface treatment for wear resistance
• Material treatment: heat-treated for impact strength

How to use

Attach the socket bit securely to a compatible 1/2" drive impact wrench or rattle gun, ensuring the retaining mechanism on the tool engages the socket. Position the hex socket onto the fastener, then apply controlled impulse power from the tool to tighten or loosen the fastener. Use steady alignment with the fastener axis to minimize slippage and rounding. After use, inspect the socket for wear or damage before storage.

Usage recommendations

Use appropriate personal protective equipment, such as eye and hand protection, when operating impact tools. Avoid using the socket on damaged or rounded fasteners. For prolonged service life, store the socket in a dry environment and avoid excessive exposure to corrosive substances.
