Williams Comfort Products JHW4-644 Shallow Impact Socket

Product Description

The WILLIAMS COMFORT PRODUCTS JHW4-644 is a 1/2 inch drive shallow impact socket designed for professional-grade fastener removal and installation. Built to SAE specification, it fits 1 3/8 inch fasteners with a 2 inch overall length. The socket features SUPERTORQUE lobular openings that increase turning power while reducing the risk of rounding fastener corners. Specially heat treated for impact use, it is engineered to handle the repeated stress of pneumatic and electric impact wrenches in demanding trade environments. Electricians, HVAC technicians, plumbers, and general mechanical trades will find this socket well suited to high-torque applications in the field or shop.

This shallow impact socket is intended for applications where clearance is limited and a standard-depth socket cannot be used without interference. The 1/2 inch drive accommodates common impact wrenches used across HVAC, plumbing, and electrical trades. The lobular opening design provides maximum engagement on 6-point fasteners, making it appropriate for torquing bolts on equipment mounts, flanges, and structural connections. Its compact 2 inch overall length fits into tighter spaces than full-depth sockets while still delivering full impact-rated performance.

Key Features

• SUPERTORQUE lobular openings increase turning power without deforming fastener surfaces
• Designed for maximum engagement on 6-point fasteners
• Compatible with pneumatic and electric impact wrenches
• Specially heat treated for impact use to provide long service life and safety
• Shallow profile at 2 inches overall length for tight-clearance applications
• 1/2 inch drive fits standard impact wrench square drives

Compatibility

Designed as an OEM-style replacement or direct-use shallow impact socket for 1/2 inch drive pneumatic and electric impact wrenches in SAE applications requiring a 1 3/8 inch socket size.

Installation Notes

This socket is installed by licensed tradespeople and experienced mechanics using 1/2 inch drive impact wrenches. Ensure the wrench is set to the appropriate torque setting before use to avoid over-torquing fasteners. Inspect the socket for cracks or deformation before each use, and replace immediately if damage is found. Do not use impact sockets with hand ratchets or torque wrenches, as the heat treatment and wall thickness are optimized for impact use only.
