## Long description

Jonnesway 1/2" 6-point 21 mm socket (model S04H4121) is a hand tool designed for use with 1/2-inch drive ratchets and torque wrenches. The six-point design provides a close fit on hex fasteners to reduce rounding and improve torque transfer. Built for workshop and field use, this 21 mm socket is intended for tasks that require secure engagement with bolts and nuts of that size.
Advantages
The 6-point profile offers increased contact area on hex fasteners compared with 12-point sockets, helping to minimize slipping and rounding. Compatibility with 1/2-inch drives allows use with a wide range of ratchets and breaker bars, while the 21 mm size covers common fasteners found in automotive and machinery applications. The socket's construction ensures consistent alignment and reliable torque delivery when used with appropriate drive tools.

How to use
