Proto J7348HT Impact Socket 1/2 in Drive 1-1/2 in 6-pt

Product Description

The PROTO J7348HT is a 6-point impact socket designed for heavy-duty fastener work in professional trade and industrial settings. Built from alloy steel, this thin-wall socket accepts a 1/2 inch drive and fits 1-1/2 inch hex fasteners. The thin-wall construction allows access in tight clearances where standard-wall sockets cannot seat properly. At 3.5 inches overall length, it provides adequate reach for most under-hood, mechanical, and structural applications. Licensed HVAC technicians, plumbers, electricians, and general mechanics will recognize this as a go-to socket for impact wrench work on large fasteners. Weighing 1.46 pounds, it is solid enough for sustained impact use without adding unnecessary bulk to a tool bag.

This socket is suited for residential and commercial service work wherever 1/2 inch drive impact tools are used. Typical applications include equipment installation, pipe flange fastening, structural bolting, and large mechanical assemblies. The 6-point contact geometry reduces fastener rounding compared to 12-point sockets, making it the preferred choice when applying high torque with a pneumatic or cordless impact driver. The thin-wall profile is particularly useful when working around conduit, pipe fittings, or tightly spaced hardware where a standard-wall socket would not clear adjacent components.

Key Features

• 1/2 inch drive fits standard impact wrenches and drive adapters
• 1-1/2 inch socket size for large hex fasteners
• 6-point contact geometry reduces the risk of fastener rounding under high torque
• Thin-wall design clears tight clearances where standard sockets will not fit
• Alloy steel construction rated for impact tool use
• 3.5 inch overall length provides reach without excessive extension

Compatibility

Designed as an OEM-style impact socket for use with 1/2 inch drive pneumatic, hydraulic, and cordless impact wrenches in professional trade and industrial applications.

Installation Notes

Installation and removal should be performed by a qualified mechanic or licensed tradesperson using a compatible 1/2 inch drive impact tool. Ensure the socket is fully seated on the fastener before applying torque to prevent slippage or fastener damage. Do not use impact sockets with hand-drive ratchets, as impact-rated and hand-tool-rated sockets have different wall thickness and metallurgy requirements. Inspect the socket for cracks or deformation before each use and retire any socket that shows visible wear.
