Jonnesway impact socket 1/2" 18 mm long S03AD4118

Jonnesway impact socket 1/2" 18 mm long S03AD4118 is a six-point, long 18 mm socket with a 1/2" drive designed for use with impact wrenches and pneumatic or electric torque tools. Intended for fastening and loosening bolts and nuts, this long impact socket provides extended reach for recessed or hard-to-access fasteners while delivering secure engagement on hex heads to reduce rounding and slipping.

Advantages

The long 18 mm design offers increased reach compared with standard sockets, allowing access to fasteners located deep within assemblies. The six-point profile ensures positive contact with hex fasteners to minimize cam-out and improve torque transfer. Constructed for impact use, the socket resists deformation under repeated high-torque cycles and is compatible with common 1/2" impact tools, making it a practical choice for workshops and maintenance tasks.

Suitable for

• Automotive wheel and suspension fasteners where extended reach is needed
• Industrial maintenance and repair tasks with recessed bolts
• Assembly and disassembly of machinery with limited access
• Use with pneumatic or electric impact wrenches and torque tools

Key specifications

• Drive size: 1/2" (square drive)
• Socket size: 18 mm (six-point/hex profile)
• Design: long/extended length for recessed fasteners
• Intended use: impact applications (pneumatic or electric tools)
• Material and finish: impact-rated alloy steel with durable surface treatment suitable for workshop use

How to use

Select the 18 mm long impact socket and securely attach it to a compatible 1/2" impact wrench or torque tool. Position the socket over the hex fastener so the six-point profile fully engages the head, then apply controlled torque. When loosening, use short bursts with an impact wrench to avoid sudden fastener ejection; when tightening, follow the torque tool manufacturer’s guidance and specified torque values for the application.

Usage recommendations

Use this socket specifically with impact-rated tools and accessories. Inspect the socket and fastener engagement before applying high torque, and replace sockets that show signs of cracking, severe wear, or distortion. For accurate torque settings, consider using a torque wrench compatible with 1/2" drive when final tightening is required.
