The PROTO J5418MH is an 18 mm, 6-point hand socket designed for 1/2 inch drive ratchets, breaker bars, and torque wrenches. Chrome-plated and built to ASME B107.5 standards, this standard-length socket delivers reliable hex engagement on fasteners in automotive, mechanical, and industrial service applications. The 6-point geometry concentrates drive force on the flat faces of the fastener rather than the corners, reducing fastener rounding under high torque loads. At 0.16 pounds, it is light enough for overhead or confined-space work without sacrificing structural integrity.
This socket is suited for professional use in automotive repair shops, fleet maintenance facilities, manufacturing environments, and general mechanical service. It fits standard 1/2 inch drive tool setups and is sized for common metric fasteners found on engines, suspension components, and equipment frames. The standard length profile works across the majority of accessible fastener locations without requiring an extension in most cases.
Designed for use with standard 1/2 inch drive hand tools including ratchets, breaker bars, and torque wrenches in professional mechanical service applications.
Installation and removal of fasteners should be performed with the drive tool fully seated and aligned to the fastener to prevent socket or fastener damage. Ensure the retaining mechanism of the drive tool is engaged before applying torque. Do not use hand sockets with impact drivers unless the socket is rated for impact use. Inspect the socket for cracks or deformation before each use and remove from service if damage is found.
