Jonnesway spline impact socket 1/2" drive M16 x 60 mm S16A4116

Jonnesway spline impact socket 1/2" drive M16 x 60 mm S16A4116 is a heavy-duty spline socket engineered for use with impact wrenches and pneumatic tools. The socket features a 1/2" square drive interface and a 60 mm depth with a spline profile sized for M16 fasteners. Built to withstand repeated high-torque impacts, it offers multiple contact points around the fastener to reduce rounding and improve torque transfer during removal and installation operations.

Advantages

The spline design distributes torque across several contact surfaces, minimizing damage to fastener heads and improving engagement on worn or rounded bolts. Constructed from impact-rated alloy steel and heat-treated for toughness, the socket resists fracturing and deformation under heavy loads. The 60 mm length provides reach into recessed fasteners while maintaining a compact form compatible with most 1/2" drive impact tools.

Suitable for

• Automotive wheel and suspension fastener removal and installation
• Industrial machinery maintenance where M16 spline fasteners are used
• General workshop and service tasks requiring impact-rated sockets
• Maintenance and repair in construction and agricultural equipment

Key specifications

• Drive size: 1/2" square drive
• Compatible fastener size: M16 spline profile
• Overall usable depth: 60 mm
• Material: impact-rated alloy steel with heat treatment
• Profile type: spline for multiple contact points

How to use

Select a compatible 1/2" drive impact wrench or extension and securely attach the spline impact socket. Ensure the socket fully seats onto the fastener spline profile before applying torque. Use controlled impact settings appropriate for the fastener and application, and avoid side loading or prying on the socket during use. After use, inspect the socket for wear or cracking and store it in a dry place to prevent corrosion.

Usage recommendations

For safe and effective operation, use the socket exclusively with impact-rated tools and accessories. Match the spline profile to M16 fasteners and avoid using the socket on damaged or mismatched bolts. Periodically inspect the socket for deformation or hairline fractures, and replace it if any damage is detected. Use appropriate personal protective equipment when operating impact tools.
