Williams Comfort Products 33621 3/4 Dr Socket 12-pt 21MM

Product Description

The WILLIAMS COMFORT PRODUCTS 33621 is a 3/4 inch drive standard socket with a 12-point opening measuring 21 millimeters. Built for demanding trade applications, this socket provides reliable torque transfer on hex fasteners in tight or standard clearance situations. The 12-point configuration allows for more engagement positions on the fastener, making it easier to work in confined areas where swing arc is limited. At 0.38 pounds, it is a solid, appropriately weighted hand tool suited for use by HVAC technicians, plumbers, electricians, and mechanical contractors who need dependable drive sockets on the job.

This socket is appropriate for use in residential and commercial mechanical service work where 3/4 inch drive tools are required. It fits standard 3/4 inch drive ratchets, breaker bars, and torque wrenches. The 21 millimeter opening makes it suitable for metric fasteners commonly found on equipment housings, flanges, pipe fittings, and structural mechanical assemblies encountered in trade service work.
