Product Description

Constant Force Spring Washers help hold parts in place in washing machines and dryers—like motor mounts and control panels—by reducing vibration. They're small, around 6–12mm across and half to one millimeter thick, and have a zinc-plated finish that looks bright silver.

The washers come in anti-static plastic bags (to keep them safe around electronics) inside small sturdy boxes with bubble wrap, so they don’t get scratched or bent. They’re tested for conductivity and to make sure the edges are smooth. They also meet the ISO 13485 standard for appliance safety, and each one is checked before shipping to make sure they fit properly.

Excellent quality

Marine-grade Constant Force Spring Washers are used to help keep dock cleats and pilings securely fastened, even when exposed to saltwater and wet conditions. They're made from 316 stainless steel (which has a matte silver look) and have a smooth split design that won’t scratch or split wood.

The washers are sealed in airtight foil bags with moisture absorbers, then shipped in plastic waterproof boxes so they stay completely dry and rust-free. They’re tested by being dunked in saltwater and tested under pressure. They also meet ISO 14001 (for eco-friendly manufacturing) and ASTM F468 standards for marine hardware, and each batch is inspected for any surface issues before shipping.

FAQ

Q: Can your Constant Force Spring Washers maintain their tension under extreme temperatures?

A: Yes, the heat-treated Constant Force Spring Washers we designed can work normally and steadily no matter in a very high temperature environment or a very low temperature environment. We can specify materials like certain stainless steels to ensure consistent spring force and prevent relaxation.
