Zinc Plated Welded Round Nuts
We provide a wide range of nuts made from low carbon steel (mild steel), medium carbon steel, alloy steel, stainless steel, brass, and aluminum alloys. To meet different requirements for corrosion resistance or strength, our nuts can be further treated with options such as heat treatment, black oxide, zinc plating, hot-dip galvanizing, black zinc coating, brass plating, nickel and chrome plating, dacomate, and more. Please specify your needs when placing an order.
A nyloc nut, also known as a nylon insert lock nut, polymer insert lock nut, or elastic stop nut, is a type of locking nut. It features a nylon collar that prevents the nut from loosening. These nuts are commonly referred to as "nylok" or "nylock." The plastic insert is placed at the end of the nut and has an inner diameter slightly smaller than the major diameter of the screw. This causes the insert to elastically deform over the screw threads without cutting into the nylon. The nylon insert creates a compressive force against the screw, effectively locking the nut in place. Nyloc nuts maintain their locking ability up to 250°F (121°C).
There is some debate about whether nyloc nuts can be reused. Some sources, like *Carroll Smith's Nuts, Bolts, Fasteners, and Plumbing Handbook*, suggest that the nylon insert is not damaged during installation and can be reused multiple times. However, the Federal Aviation Administration allows reuse only if the prevailing torque is within specification. On the other hand, some military specifications require replacement of self-locking nuts in critical applications. Aerospace-grade self-locking nuts must maintain running torque after several assembly cycles without preloading the fastener.
