Proto J7316HT 1/2 in Drive 1/2 in Hex Impact Socket 6-pt

Product Description

The PROTO J7316HT is a 1/2 inch drive, 1/2 inch hex impact socket built for high-torque power tool applications in the trades. Constructed from alloy steel, this 6-point thin wall socket is designed to withstand the repeated shock loads produced by pneumatic and electric impact wrenches. The 3.25 inch overall length provides reach in tighter installation spaces without sacrificing grip on the fastener. At 0.42 pounds, it delivers solid mass without adding unnecessary bulk to a tool bag. The thin wall profile makes it a practical choice where clearance around the fastener head is limited, a common constraint in HVAC, plumbing, and mechanical service work.

This socket fits standard 1/2 inch square drive impact wrenches and is suited for residential and light commercial mechanical applications. Typical use cases include equipment mounting fasteners, pipe flange bolts, and structural hardware encountered during HVAC unit installation, plumbing rough-in, and general mechanical service. The hex drive configuration engages 1/2 inch hex-head fasteners directly, providing full flat-to-flat contact to reduce fastener rounding under impact load.

Key Features

• 1/2 inch square drive compatible with standard impact wrenches
• 1/2 inch hex socket size for direct engagement on hex-head fasteners
• 6-point geometry maximizes contact area and reduces fastener rounding
• Thin wall design improves clearance in tight fastener locations
• Alloy steel construction rated for impact tool use
• 3.25 inch overall length provides reach without excessive extension

Compatibility

Designed for use with 1/2 inch drive impact wrenches accepting standard square-drive impact sockets. Fits 1/2 inch hex-head fasteners.

Installation Notes

This socket is intended for use with impact wrenches only — do not use with standard ratchets or torque wrenches, as impact-rated sockets and hand-tool sockets have different metallurgical properties. Ensure the socket is fully seated on the drive anvil and the fastener before applying power. Follow applicable torque specifications for the fastener and joint type as required by local mechanical codes. Inspect the socket periodically for cracks or deformation and remove from service if damage is found.
