Thin-Wall 6-Point Impact Sockets

With a smaller OD than standard sockets, these fit between tightly spaced fasteners. They are made to withstand the high torque and force of impact tools.

Black-Oxide Steel

3/4" Square Drive—_3/4" square drive size sockets require a locking retainer. Use with an impact wrench that has a pin-style socket retainer, or use a socket retaining ring with tools that have a hole- or hole-and-ring style socket retainer.

Nonmarring 6-Point Impact Socket Sets


	6-Point Socket

Tighten or loosen nuts and bolts without damaging the finish. The tough steel core of the socket withstands the high torque of impact tools, but the insert and outer sleeve are made of plastic, which won’t scratch chrome plating and other coatings. The hex shape achieves the best possible grip on hex fasteners to prevent rounding their points.

Continuous-Duty Fastener-Holding 6-Point Sockets

A magnet holds the fastener securely enough to drive self-tapping screws. These sockets are designed to tolerate continuous use with power tools and impact tools in high-volume production and assembly. They’re hardened to resist cracking and wear from repeated use, so they’ll last longer than standard impact sockets. The hex shape achieves the best possible grip on hex fasteners to prevent rounding their points.

Ring with Crush

Gauge

The pin on these retainers is permanently connected to the ring, so they're less likely to dislodge when used with an impact wrench compared to two-piece retaining rings. Use them to secure impact sockets and adapters to a tool that has a hole- or a ring-and-hole style retainer.

For 3/4" Square Drives, For 1" Square Drives, and For 1 1/2" Square Drives—Rings for _3/4" square drive and larger have a crush gauge on the pin that deforms when sockets become worn and need to be replaced.

Continuous-Duty Hex Bit Sockets


	For Hex Drives

These sockets are designed to tolerate continuous use with power tools and impact tools in high-volume production and assembly. They’re hardened to resist wear from repeated use, so they’ll last longer than standard impact sockets. The bit is replaceable—swap out a worn or broken bit with one of the same size.

These sockets require a locking retainer. Use with an impact or power tool that has a pin-style socket retainer, or use a socket retaining ring with tools that have a hole- or hole-and-ring style socket retainer.

Impact Socket Extensions

Attach to your socket for a longer reach. These extensions are made to withstand the high torque and force of impact tools.

3/4" Square Drive—_3/4", 1", and 1 _1/2" square drive size extensions require a locking retainer. Use with an impact wrench that has a pin-style socket retainer, or use a socket retaining ring with tools that have a hole- or hole-and-ring style socket retainer.

Stretch-Fit One-Piece Socket Retaining Rings

Stock fewer sizes of retaining rings—these stretch to fit a range of socket diameters. They have a retaining pin to secure your impact sockets and adapters to a tool that has a hole- or ring-and-hole-style retainer. A crush gauge on the pin deforms when the socket becomes worn and needs to be replaced. You can reuse these rings, but only on the same size or larger socket.
