Spiralock captive washer nut offers controlled friction on the bearing surface to guarantee a tight fit regardless of surface finish of the mating component. It also reduces tightening friction (k-factor) to yield more clamp load and it provides protection of the bearing surface from tightening damage. (read more)

In addition to the basic benefits of the unique Spiralock thread such as vibration loosening resistance, reusability, elimination of secondary locking devices, improvement in quality and joint fatigue life and reduction of costs, this nut is equivalent to MS21042 and MS21043 except for the prevailing torque feature which is replaced by the Spiralock locking thread technology.

NutLok is a unique, RoHS compliant captive hardware system that secures a rotating nut to a FusionLug cable and lug termination assembly (also available from Cableco) or a bus bar. Made of tin-plated brass, the fastener is free to tighten a connector onto the mating surface. (read more)

Technological advancements are reducing the costly effects of hydraulic system leakage, and Gates Full-Torque Nut™ couplings are leading the way. This advanced coupling for wire-braid and spiral-wire hydraulic hose assemblies combats over-torquing. Its large holding shoulder evenly distributes stress forces for unsurpassed resistance to nut cracking and seat damage. (read more)

Visumatic's VNR Automatic Nut Driver features our exclusive "X-Thread Eliminator" and is your highest assurance against cross threading. Handheld or fixed system, the VNR Nut Driver features a spring-loaded pad behind the nut so the nut is flat with respect to the socket before driving. Nosepiece permits access anywhere you can put a socket. The nut is extended so the operator can see it. (read more)
