Specifications

Designed for Square Fasteners

Unlike standard 6-point sockets intended primarily for hex-head fasteners, this 8-point socket is designed to engage square-head fasteners.

This makes it particularly useful for professional installation and repair work where square-head bolts, set screws, and related hardware are used.

Impact-Rated Construction

The socket is engineered for the higher torque and repetitive forces produced by impact tools. High-strength steel construction helps maintain durability while allowing relatively thin socket walls for improved access around recessed or obstructed fasteners.

Common Applications

Suitable for:

• Garage door installation and repair

• Commercial overhead door service

• Square-head bolts and nuts

• Mechanical maintenance

• Industrial equipment

• Construction and fabrication

• Professional service trucks and tool kits

Safety

Always verify that the socket size matches the fastener before use. Inspect the socket for cracks, deformation, or excessive wear before operating an impact tool.

Use appropriate eye protection and other required personal protective equipment when working with hand or power tools. Do not use damaged sockets.
