Proto J5418M 18mm 12-point 1/2 Drive Hand Socket

Product Description

The PROTO J5418M is an 18 mm, 12-point hand socket designed for 1/2 inch drive ratchets, breaker bars, and torque wrenches. The 12-point configuration allows engagement at 30-degree increments, giving technicians more positioning options in tight spaces. A chrome-plated finish protects against corrosion and makes cleanup faster after use. At standard length, this socket handles the majority of fastener access situations without the clearance concerns of deep-well versions. It weighs 0.15 pounds and measures approximately 3.3 inches in length with a 0.8-inch profile. HVAC technicians, mechanics, and plumbers who work with metric fasteners on equipment panels, flanges, and brackets will find this a direct-use addition to a 1/2 inch drive set.

This socket suits residential and light commercial service work where 18 mm metric fasteners appear on equipment housings, motor mounts, pipe flanges, and structural brackets. Standard-length geometry keeps the socket practical for open fastener access without the added height of extended or deep-well designs. It packages individually, making it a straightforward single-piece replacement or addition to an existing socket set.

Installation Notes

Install and remove fasteners using a properly rated 1/2 inch drive ratchet or torque wrench. Ensure the socket is fully seated on the fastener before applying load to avoid rounding. Disconnect power or shut off relevant systems before servicing equipment with this socket. Inspect the socket for cracks or deformation before each use and retire any damaged tooling.
