Bolt-Through Socket Wrenches


	6-Point Openings	12-Point and 6-Point Openings

6-Point

Openings

12-Point

Openings

Turn nuts on bolts and threaded rods, which can pass through the short end of the wrench. For additional leverage, slip a bar through the short end to create a T-handle.

12-Point Opening—Wrenches with a 12-point opening are easier to position on hex fasteners than wrenches with a 6-point opening but make less contact.

Bolt-Through Ratchet Wrenches

Pair these wrenches with a bolt-through socket to reach nuts at the bottom of a long threaded rod or bolt which can pass through the head of the wrench. These wrenches have a ratchet mechanism that allows you to turn fasteners without removing and repositioning the tool.

Bolt-Through 6-Point Sockets

Pair these sockets with a bolt-through ratchet wrench to reach nuts at the bottom of a long threaded rod or bolt which can pass through the socket and the head of the wrench. The hex shape achieves the best possible grip on hex fasteners to prevent rounding their points. For use with hand-drive tools only.
