Apex 80331 Socket 3/8 Drive 6 Point 21 Mm Chrome

Product Description

The APEX 80331 is a 3/8 inch drive, 6-point, 21 MM full polish chrome socket designed for professional-grade fastener work. The 6-point geometry uses an off-corner loading design that directs force onto the flats of a fastener rather than the corners, reducing the risk of rounding and improving durability over repeated use. Large, hard-stamped size markings on the socket body allow for fast identification in a tool tray or bag. At 1.102 inches in length, this is a standard-length socket suited for general-purpose work across automotive, mechanical, and industrial applications. It weighs 0.19 pounds.

This socket is intended for use with 3/8 inch drive ratchets, extensions, and torque wrenches in professional shop, fleet, and field service environments. The full polish chrome finish resists corrosion and makes cleaning straightforward after contact with grease, oil, or shop fluids. It is well-suited for automotive technicians, mechanical contractors, and maintenance professionals who work with metric fasteners regularly. The 21 MM size is commonly encountered on suspension components, exhaust hardware, and engine accessories.

Installation Notes

Socket installation and use does not require licensed trade credentials, but should always be performed with properly rated drive tools matched to the fastener torque requirements. Ensure the socket is fully seated on the fastener and drive tool before applying torque to avoid slippage. Inspect the socket for cracks or wear before use, particularly in high-cycle shop environments. Do not use hand sockets with impact drivers unless the socket is impact-rated.
