Proto J5274HAM 11mm 6-point 3/8 Drive Hand Socket

Product Description

The PROTO J5274HAM is an 11 mm, 6-point hand socket designed for 3/8 inch drive ratchets and extensions. Machined from alloy steel with a chrome-plated finish, it delivers reliable corrosion resistance and a clean surface for easy identification in the field. At 1.75 inches overall length, the J5274HAM is a compact, standard-depth socket suited for fastener work in tight spaces. It meets ASME B107.5M standards for hand socket dimensions and performance. Mechanics, HVAC technicians, plumbers, and electricians all rely on properly spec-rated sockets like this for daily service work across residential and commercial applications.

The J5274HAM is well suited for general mechanical and trade service tasks where an 11 mm fastener is present. Common applications include equipment access panels, motor mounts, valve assemblies, electrical enclosures, and light structural hardware. The 6-point contact geometry reduces the chance of fastener rounding compared to 12-point designs, making it a practical choice when working with worn or heavily torqued hardware. This socket fits standard 3/8 inch drive tool setups that are common across most professional tool kits.

Installation Notes

Install and remove fasteners only when equipment is safely powered down, de-energized, or depressurized per applicable service procedures. Use a calibrated torque wrench when a specific fastener torque is required by the equipment manufacturer. Inspect the socket for cracks or deformation before each use and retire any damaged socket immediately. Do not use impact drivers with this hand socket unless the socket is rated for impact use.
