Apex 80818 Socket 1/2 in Drive 12 Point 21 Mm Chrome

Product Description

The APEX 80818 is a full polish chrome socket designed for 1/2 inch drive applications, featuring a 12-point configuration in a 21 MM size. Built for professional trade use, this socket delivers reliable fastener engagement in tight or demanding work environments. The off-corner loading design applies force to the flats of fasteners rather than the corners, reducing fastener rounding and improving tool longevity. Large, hard-stamped size markings make identification fast in a busy tool bag or socket rail. At 0.43 pounds and 3.031 inches in length, this socket suits a wide range of standard service tasks performed by mechanics, pipefitters, electricians, and other trade professionals.

This socket is suited for general mechanical and maintenance work across residential, commercial, and light industrial settings. The 1/2 inch drive interface pairs with standard 1/2 inch ratchets, breaker bars, and torque wrenches. The 12-point design provides more engagement positions in confined areas where swing arc is limited. The full polish chrome finish resists corrosion and simplifies cleanup after service work. It is sold individually and is appropriate for fastener removal and installation tasks encountered in HVAC, plumbing, electrical panel work, and general equipment maintenance.

Installation Notes

This socket is installed and removed by hand onto a 1/2 inch drive tool — no special tooling is required. Ensure the socket is fully seated on the fastener before applying torque to prevent slippage or fastener damage. Inspect the socket for cracks or wear before use, particularly in high-torque applications. Follow applicable service procedures and torque specifications provided by the equipment manufacturer.
