Bi-Hex Socket Sets
Bi-hex socket sets include sockets that have 12 internal sides (also known as bi-hex) and are designed to fasten/unfasten bolts with six sides. Bi-hex sockets work by fitting over the fastener and gripping each its corners.
Many bi-hex socket sets also include hand tools like ratchets, which attach to the socket via a square drive and provide the leverage to turn the fastener, however bi-hex sockets can also be used with tools like torque wrenches, powered ratchet wrenches and sliding t-handles.
Bi-hex sockets sets are used by mechanics, maintenance engineers, aerospace engineers and DIYers.
