Williams Comfort Products JHW4-640 Shallow Impact Socket

Product Description

The WILLIAMS COMFORT PRODUCTS JHW4-640 is a shallow impact socket built for professional-grade fastener work. Designed with a 1/2 inch drive and a 1-1/4 inch SAE opening, this socket measures 2 inches in overall length, keeping it compact for tight-clearance applications. The lobular internal geometry — a SUPERTORQUE profile — grips fastener flats more deeply than standard hex geometry, reducing the chance of rounding under high torque loads. The socket is specially heat treated to handle the repeated stress cycles of pneumatic and electric impact wrenches. Licensed tradespeople, maintenance mechanics, and service technicians working in industrial and commercial settings will find this tool suited to demanding daily use.

This shallow impact socket is used wherever a compact socket profile is needed on 6-point fasteners. Its 2-inch overall length makes it appropriate for applications where a standard or deep socket would interfere with surrounding structure or hardware. Compatible with 1/2 inch drive pneumatic impact wrenches and electric impact wrenches, it fits naturally into a service tech's existing 1/2 inch drive set. It is sold as an individual socket, making it a practical replacement or addition to an existing impact socket collection.

Key Features

• SUPERTORQUE lobular opening profile maximizes grip on 6-point fasteners and reduces fastener deformation under load
• Shallow profile at 2 inches overall length suits tight-clearance fastener access
• 1/2 inch drive accepts standard 1/2 inch pneumatic and electric impact wrenches
• 1-1/4 inch SAE opening size for common large-fastener applications
• Specially heat treated for impact use, providing long service life and resistance to fracture under repeated impact cycles

Compatibility

Designed as an OEM-style impact socket for use with 1/2 inch drive pneumatic and electric impact wrenches requiring a shallow 1-1/4 inch SAE socket.

Installation Notes

This socket is intended for use by qualified mechanics and service technicians familiar with impact tool operation. Always ensure the socket is fully seated on the drive anvil before applying torque, and inspect the socket for cracks or deformation before each use. Do not use impact sockets with standard ratchets or torque wrenches, as impact-rated tools are engineered specifically for percussive torque loads. Wear appropriate eye protection when operating pneumatic or electric impact equipment.
