6-Point Stainless Steel Sockets

6-Point

Socket

Designed for use with stainless steel fasteners, these sockets are more corrosion resistant than steel sockets and less likely to flake. They help you avoid the rust and contamination that steel flakes can cause when they’re left behind. The hex-shaped drive provides the best possible grip on hex fasteners and prevents rounding. Only use with hand-driven tools.

Dual-Size 12-Point Impact Socket Sets


	Dual-Size View	12-Point Socket

Use one socket to switch between two fastener sizes. The spring-loaded innermost wall stays in place for smaller fasteners; push the socket onto a larger fastener and this wall slides out of the way.

With twice as many corners, 12-point sockets grab onto hex-drive fasteners more quickly than 6-point sockets. They also match the external 12-point screws commonly found in heavy duty vehicles such as bulldozers and excavators. Also known as double-hex sockets. These sockets are sturdier and have more give than manual-drive sockets, so they'll withstand the high torque and force of impact tools.

Wrench Heads


Wrench and Socket Extension Not Included

Reach nuts obstructed by a fluid line or other barrier with these wrench heads. Connect them to your socket extension and ratchet wrench to turn fasteners where clearance is limited from both the top and side. You can also attach one directly to your ratchet wrench to convert it into an open-ended ratcheting wrench. Also known as crowfoot wrenches.
