Socket 3/8" 16mm (6-point) Rockforce RF-53516

Rockforce RF-53516 is a 3/8" drive 16 mm 6-point socket designed for fastening and loosening hex fasteners. Engineered for use with 3/8" ratchets, torque wrenches and extensions, this medium-size hand socket offers a 6-point contact profile that helps reduce rounding on bolts and nuts and provides secure engagement during torque application. The socket is intended for general automotive, maintenance and assembly operations where reliable torque transfer and accurate fit are required.

Advantages

The 6-point internal profile delivers improved grip on hex heads compared with 12-point sockets, reducing the chance of fastener damage. Compatibility with 3/8" drive tools makes it versatile for common workshop ratchets, torque wrenches and extensions. The 16 mm size covers a wide range of medium fasteners used in vehicles and machinery. The socket's construction and finishing provide a balance between durability and ease of cleaning after use.

Suitable for

• Automotive repair and wheel component work
• General maintenance and service tasks
• Assembly and disassembly of machinery with 16 mm hex fasteners
• Workshops using 3/8" drive ratchets and torque wrenches

Key specifications

• Drive size: 3/8" (9.5 mm)
• Socket size: 16 mm
• Internal profile: 6-point (hex)
• Intended use: hand tool for fastening and loosening hex fasteners
• Compatibility: designed for use with ratchets, torque wrenches and extensions with 3/8" drive

How to use

Select the socket and attach it securely to a compatible 3/8" drive ratchet, breaker bar or torque wrench. Place the socket fully onto the hex fastener, ensuring even contact on all six points before applying torque. For loosening tight or corroded fasteners, use a breaker bar or apply penetrating lubricant first and use steady, controlled force. When precision torque is required, use a calibrated torque wrench and follow the specified torque values for the fastener.

Usage recommendations

For best results, keep the socket clean and free of debris, inspect the internal profile for wear before use, and avoid using impact tools unless the socket is specifically rated for impact use. Use appropriate personal protective equipment and follow torque specifications to prevent fastener or tool damage.
