Proto J4718T Hand Socket 9/16 in 12-point 1/4 in Drive

Product Description

The PROTO J4718T is a 9/16 inch, 12-point hand socket designed for use with a 1/4 inch drive ratchet or extension. Built from alloy steel with a chrome-plated finish, this standard-length socket provides corrosion resistance and a clean appearance suited to professional toolboxes. The 12-point design allows engagement at 30-degree increments, making it easier to work in confined spaces where full handle swing is limited. It meets ASME B107.1 standards and carries a lifetime warranty, confirming its suitability for daily professional use in mechanical, HVAC, plumbing, and electrical service work.

This socket is appropriate for general fastener work across residential and commercial service applications. It fits standard 1/4 inch drive tool sets and is well-suited for tasks requiring a compact drive size, such as panel work, equipment access covers, and light-duty fastener removal in tight quarters. Technicians across trades who carry a 1/4 inch drive set will find this a reliable standard addition for 9/16 inch fasteners encountered in the field.
