This guide is for mechanics and DIY enthusiasts who need to tackle hard-to-reach fasteners. The AB Tools 7/16 WW Whitworth socket offers a deep profile and 12-point grip for enhanced access and torque, though its specialized Whitworth sizing means it's not for standard metric or imperial fasteners. It's a durable, high-strength socket designed for professional and occasional use.

WW stands for Whitworth, a system of screw threads originating in England. Unlike modern metric or UNC/UNF (Imperial) threads, Whitworth threads have a different angle and pitch. The 7/16 WW refers to a specific size within this system.
No, this socket is specifically designed for 7/16 WW Whitworth fasteners only. Using it on other thread types can damage the fastener and the socket, and will not create a secure fit.
A 12-point socket offers twice as many points of contact with the fastener head, allowing for engagement at finer increments (every 30 degrees instead of 60 degrees). This makes it easier to position the socket on fasteners in tight spaces and provides better grip, especially on worn fasteners.
The drive size is 3/8-inch. This is the square receptacle on the socket that connects to the drive tool (like a ratchet or extension).
The socket is made from CR-v (Chrome Vanadium) steel. This alloy provides a good balance of hardness for strength and toughness to resist chipping and breaking, making it suitable for high-torque applications.
The total depth of the socket is 65mm.
While made of strong CR-v steel, it is primarily designed for manual tools like ratchets and torque wrenches. Use with impact wrenches should be cautious and infrequent, as high-impact forces can potentially damage the socket or fasteners over time.
Verify that the fastener is indeed a 7/16 WW Whitworth size. This socket is specific to the Whitworth standard and will not fit metric or standard imperial fasteners.
Ensure the socket is fully seated onto the fastener head. Check for damage or rounding on both the socket's internal points and the fastener. Clean both surfaces to remove any contaminants.
Use a 3/8-inch drive extension bar to increase the reach. Ensure the extension is compatible and securely attached to both the socket and the drive tool.
Discontinue use immediately. Inspect the socket for damage. If compromised, replace the socket to prevent failure under load.
Setup: No complex setup is required. Simply attach the 7/16 WW Whitworth socket to a compatible 3/8-inch drive ratchet, extension, or power bar. Ensure the socket is securely seated on the drive tool.
Compatibility: This socket is designed for 7/16 WW Whitworth fasteners. It is compatible with all standard 3/8-inch drive tools, including ratchets, breaker bars, torque wrenches, and impact wrenches (use with caution on impact tools to avoid damage).
Care: To maintain its performance and longevity:
