Apex SA-58-18M Hand Socket 1/2 in Drive 18 Mm 6-point

Product Description

The APEX SA-58-18M is an 18 mm, 6-point hand socket with a 1/2 inch square drive, built from alloy steel for durability in professional hand-tool applications. The bright, uncoated finish resists buildup and allows for quick visual inspection of the socket surface. At 97.80 mm (approximately 3.85 inches) overall length, the SA-58-18M delivers the reach needed for fasteners seated in moderate-depth applications. It meets ASME B107.2, B107.33M, and B107.110 standards, making it a code-compliant choice for trade and industrial use. The socket is tether-capable, supporting drop-prevention programs on elevated jobsites or in overhead service environments.

The SA-58-18M is suited for general mechanical, HVAC, plumbing, and electrical trade work wherever metric fasteners are encountered. The 18 mm size is common on equipment mounting hardware, flanges, and mechanical assemblies across residential and commercial service work. The 6-point geometry reduces fastener rounding compared to 12-point designs, making it a reliable choice for tight or corroded fasteners. This socket is used by technicians who require a metric, square-drive tool that integrates with standard 1/2 inch drive ratchets and extensions.

Key Features

• 18 mm, 6-point socket minimizes fastener rounding on metric hardware
• 1/2 inch square drive interfaces with standard ratchets, breaker bars, and torque wrenches
• Alloy steel construction for strength under high-torque hand use
• Tether-capable design supports drop-prevention programs on elevated or restricted-access jobsites
• Meets ASME B107.2, B107.33M, and B107.110 standards
• Bright, uncoated finish for easy inspection and cleaning

Compatibility

Designed for use with standard 1/2 inch square drive ratchets, extensions, and torque wrenches. Compatible with metric fastener applications per ASME B107.2 specifications.

Installation Notes

Install and remove hand sockets with the drive tool fully seated to prevent slippage under load. De-energize or de-pressurize equipment before servicing fasteners on live electrical, HVAC, or plumbing assemblies per applicable NEC, IFGC, or IPC guidelines. Inspect the socket for cracks or wear before use, and do not use impact drivers with this hand-rated socket unless the socket is specifically rated for impact use.
