Proto J5274HA 7/16 in 6-point 3/8 Drive Hand Socket

Product Description

The PROTO J5274HA is a 7/16 inch, 6-point hand socket designed for professional-grade fastener work in mechanical, HVAC, and industrial service applications. Built from alloy steel with a chrome-plated finish, this socket features a universal/flex configuration that allows access to fasteners in tight or angled positions. The 3/8 inch drive size suits a wide range of ratchets and drive tools commonly found in trade toolkits. At 1-25/32 inches overall length, it is compact enough for close-quarters work while providing solid torque transfer on hex fasteners.

This socket is suited for residential and commercial service work where a flex-style socket provides an advantage over fixed-drive designs. Typical applications include HVAC equipment access panels, plumbing fixture hardware, and general mechanical assembly where fastener orientation is not perpendicular to the work surface. The 6-point contact geometry reduces the risk of rounding fastener heads compared to 12-point designs, making it a practical choice for production and field service environments. Compatible with standard 3/8 inch drive ratchets, extensions, and flex handles.

Key Features

• Universal/flex socket type for angled fastener access
• 6-point design reduces fastener rounding under high torque
• Alloy steel construction for durability in heavy-use environments
• Chrome-plated finish resists corrosion and simplifies cleaning
• Meets ASME B107.1 standards for hand socket performance
• Compact 1-25/32 inch overall length for close-quarters use

Compatibility

Designed for use with standard 3/8 inch drive ratchets, extensions, and accessories. Fits 7/16 inch hex fasteners in universal/flex drive applications.

Installation Notes

Install and remove using a 3/8 inch drive ratchet or breaker bar rated for the torque requirements of the fastener being serviced. Ensure the drive square is fully seated before applying force to prevent socket or tool damage. Inspect the chrome finish and socket walls for wear or cracking before each use, and retire the socket if deformation is observed. This socket is not tether capable and should not be used in elevated work environments where dropped-tool hazards apply without supplemental retention measures.
