Spline impact socket 1/2" Jonnesway S16A4112 M12 x 60 mm

Jonnesway spline impact socket 1/2" S16A4112 is a heavy-duty 1/2" drive socket designed for M12 fasteners with a 60 mm length. Engineered for use with impact wrenches, this spline-profile socket delivers reliable torque transmission and is built to withstand repeated shock loading in automotive, industrial and workshop environments. The socket's spline geometry provides multiple contact points on fastener heads, reducing the risk of rounding and improving engagement on slightly damaged or worn fasteners.

Advantages

The spline design offers improved grip distribution across the fastener, enabling more consistent torque application and reducing slippage. Constructed from impact-rated alloy steel and heat-treated for durability, the socket resists cracking and deformation under high-torque impact use. Its 1/2" drive interface ensures compatibility with common impact wrenches and extensions, while the 60 mm length provides clearance for recessed or partially threaded fasteners.

Suitable for

• Automotive repair and wheel, brake or suspension fasteners
• Industrial maintenance and assembly where high torque is required
• Workshop use with impact wrenches and air or electric tools
• Removal of slightly rounded or worn M12 fasteners

Key specifications

• Drive size: 1/2"
• Fastener size/profile: M12 spline
• Length: 60 mm
• Material: impact-rated alloy steel (heat-treated)
• Finish: corrosion-resistant coating
• Application: designed for use with impact wrenches

How to use

Select the spline impact socket matching the M12 fastener size and attach it securely to a compatible 1/2" drive impact wrench or breaker bar. Ensure the socket fully seats on the fastener head before applying torque. When using an impact wrench, apply short bursts of power and maintain a steady stance; if a fastener is seized, use penetrating lubricant and apply torque gradually to avoid sudden breakage. After use, inspect the socket for cracks or rounding and store it in a dry tool case or rack.

Usage recommendations

Use the socket only with impact-rated tools and accessories. Avoid using non-impact hand tools with impact sockets, and do not exceed the recommended torque capacity of your impact wrench or the fastener specification. Regularly inspect the socket for wear or damage and replace it if any deformation or cracking is detected to maintain safe operation.
