Proto J5273HAM 10 Mm 6-point Hand Socket 3/8 Drive

Product Description

The PROTO J5273HAM is a 10 mm, 6-point hand socket designed for professional-grade fastener work. Built from alloy steel with a chrome-plated finish, it fits a 3/8 inch drive ratchet or breaker bar and measures 1.75 inches in overall length. The 6-point geometry delivers full contact on hex fasteners, reducing the risk of rounding at high torque. This socket is intended for use by mechanics, HVAC technicians, plumbers, and other trade professionals who require a reliable, standard-profile socket for daily service work.

The J5273HAM suits a wide range of maintenance and repair applications where a 10 mm fastener is encountered. Common scenarios include equipment panel removal, mechanical assembly, and general service tasks across residential and commercial jobsites. Its compact 1.75 inch length makes it suitable for moderately confined fastener access on machinery, HVAC equipment, and plumbing fixtures. The chrome finish resists corrosion in typical shop and field environments.

Installation Notes

This socket is installed by a mechanic or trade technician as part of routine fastener removal or installation. Ensure the drive tool is fully seated before applying torque to prevent slippage or socket damage. Inspect the socket for cracks or wear before each use, and do not use impact drivers with hand sockets unless the socket is rated for impact use. Store in a dry location to preserve the chrome finish.
