Custom Washers Silicone Nylon Insulation Gaskets Flat Spacer Ring Pads

The custom washers are thin plates (typically disk-shaped) with a hole (typically in the middle) that is normally used to distribute the load of a threaded fastener, such as a screw or nut. Other uses are as a spacer, spring (Belleville washer, wave washer), wear pad, preload indicating device, locking device, and to reduce vibration (rubber washer). Washers usually have an outer diameter (OD) about twice larger than their inner diameter (ID). Ever Hardware provides custom washers and customizable packaging.

Washers are usually metal or plastic. High-quality bolted joints require hardened steel washers to prevent the loss of pre-load due to Brinelling after the torque is applied.
Rubber or fiber gaskets used in taps (or faucets, or valves) to stop the flow of water are sometimes referred to colloquially as washers; but, while they may look similar, washers and gaskets are usually designed for different functions and made differently.
Washers are also important for preventing galvanic corrosion, particularly by insulating steel screws from aluminum surfaces.

Nylon is a generic designation for a family of synthetic polymers, more specifically aliphatic or semi-aromatic polyamides. They can be melt-processed into fibers, films, or shapes. The first example of nylon (nylon 6,6) was produced on February 28, 1935, by Wallace Carothers at DuPont’s research facility at the DuPont Experimental Station. Nylon polymers have found significant commercial applications in fibers (apparel, flooring, and rubber reinforcement), in shapes (molded parts for cars, electrical equipment, etc.), and in films (mostly for food packaging). Use these Nylon Spacers with bolts and screws to maintain space between the head and the surface. These spacers are constructed from durable nylon material.
