Gripco Crownlock Torque Nuts

This tough one-piece nut is built to withstand vibrations and resist loosening at the joint.

Gripco Centerlock Torque Nuts

Gripco Centerlock Torque Nuts offer a predictable torque at tension which is important for critical joints.

Gripco Twin Delta Torque Nuts

Gripco Twin Delta Torque Nuts resist loosing of the joint and offer predictable torque at tension, which is important for critical joints.

Gripco Toplock Torque Nuts

These prevailing torque nuts are designed for use in non-critical applications with Grade 2 bolts. 

Gripco Hex Nuts

Gripco hex clinch nuts are designed with a hex pilot to prevent rotation in a hex hole.

Gripco Hex Flange Clinch Nuts

Gripco Hex flange clinch nuts can be automatically fed and clinched on volume production lines or individually clinched with riveters, orbital riveters, or arbor-type presses.

Gripco Round Flange Clinch

Gripco Round Flange Clinch are designed with a larger bearing surface to support sheet metal applications with lower tensile strength, such as aluminum.

Gripco Countersunk Weld Nuts

Gripco Countersunk Weld Nuts are manufactured from low-carbon steel and are designed to eliminate the time-consuming re-tapping of threads frequently required after welding.

Gripco Square Weld Nuts

Gripco Square Weld Nuts are engineered to meet Class 5 - Class 9 proofloads in a weldable application.

Gripco Flange Weld Nuts

Gripco Flange Weld Nuts are engineered with greater hoop strength and capable of meeting Class 10 proofloads in a weldable application.

Gripco Round Weld Nuts

Gripco Round Weld Nuts yield a better weld schedule and performance than a standard hex weld nut due in part to a larger bearing surface.
