Proto J5425MH Hand Socket 25mm 6-point 1/2 Drive

Product Description

The PROTO J5425MH is a 25 mm, 6-point hand socket designed for 1/2 inch drive ratchets, breaker bars, and torque wrenches. Machined from alloy steel with a chrome-plated finish, this standard-length socket delivers reliable fastener engagement and corrosion resistance in professional shop and field use. The 6-point geometry reduces fastener rounding compared to 12-point designs, making it a preferred choice for high-torque applications. Overall length measures 1.53 inches, keeping the profile compact for work in moderately tight clearances. Meets ASME B107.5 standards for hand socket tools.

Suited for mechanical, industrial, and maintenance applications where a 25 mm fastener size is common. The 1/2 inch drive sizing places this socket in the range typically used by automotive technicians, heavy equipment mechanics, pipefitters, and industrial maintenance trades. Standard length fits most open-access fastener scenarios on engines, machinery, structural assemblies, and equipment frames. The chrome finish makes the socket easy to wipe clean and helps resist surface rust in typical shop environments.
