E8 Wrenches | McMaster-Carr

Tighten and loosen fasteners with an external Torx drive. These sockets have more contact with Torx fasteners than 6-point sockets do with hex fasteners, so you can apply more twisting force without damaging the drive. Use them with hand-driven tools only.

Two-Head Ratcheting Box Wrenches

Torx Openings

Ratchet mechanisms allow you to turn fasteners in tight spaces without removing and repositioning the tool. Wrenches with 12-point openings are easier to position on hex fasteners than wrenches with 6-point openings but make less contact. The smaller the turn required to ratchet, the less clearance you need to engage the ratchet.

Ratcheting Box Wrench Sets

A ratchet mechanism allows you to turn fasteners in tight spaces without removing and repositioning the wrench. The smaller the turn required to ratchet, the less clearance you need to engage the ratchet. These wrenches are polished for a mirror-like finish.
