Williams Comfort Products JHW4M-618 Impact Socket 18MM

Product Description

The WILLIAMS COMFORT PRODUCTS JHW4M-618 is a shallow impact socket designed for metric fastener applications in professional trade environments. Built with a 1/2 inch drive and sized at 18 MM, this socket fits standard pneumatic and electric impact wrenches used by mechanics, industrial maintenance technicians, and trade professionals. The lobular internal opening geometry increases turning power while reducing fastener deformation under high-torque conditions. At 0.22 pounds and 1.5 inches in overall length, it is a compact, durable tool suited for tight-clearance work where a standard-depth socket would not fit.

This shallow impact socket is intended for use in automotive, industrial, and mechanical maintenance applications where metric fasteners are common. The 18 MM size covers a wide range of bolts and nuts found in equipment assemblies, HVAC mechanical connections, and structural fastener work. Its short overall length makes it practical in confined spaces. It is sold individually and compatible with 1/2 inch drive impact tools commonly found in trade shops and field service kits.

Key Features

• Lobular opening design increases torque transfer and reduces fastener rounding
• Shallow profile at 1.5 inches overall length for use in tight clearance areas
• Rated for use with pneumatic and electric impact wrenches
• Specially heat treated for impact service to extend service life and maintain safety
• Metric sizing at 18 MM for wide fastener compatibility
• 1/2 inch drive fits standard impact wrench anvils

Compatibility

Designed as an OEM-style replacement and standard fitment shallow impact socket for use with 1/2 inch drive pneumatic and electric impact wrenches accepting metric shallow sockets.

Installation Notes

Install and remove only when the drive tool is powered down or the air supply is disconnected. Confirm the socket is fully seated on the drive anvil and retaining pin or ring is engaged before applying torque. Do not use impact sockets on hand ratchets for extended torque applications, as impact-rated sockets are designed specifically for dynamic shock loads from impact tools. Inspect the socket for cracks or deformation before each use.
