Hex Nut Cup Washer One‑Piece Cold‑Forged for Automotive And Industrial Use

We came up with this Hex Nut Cup Washer One‑Piece Cold‑Forged for Automotive And Industrial Use from Qimao Metal Manufacturer because customers kept asking for a faster way to fasten things from one side. You know how it goes — you’re under a trailer or inside a machine panel, trying to hold a washer and a nut while also lining up a bolt from the other side. It never works smoothly. So we welded the hex nut right into the cup washer. Now it’s one solid piece. The nut won’t spin, the washer won’t fall off, and you don’t need to reach around to the back of the panel. Push the bolt through, thread it into the welded nut, and tighten. Finally, done.

We make these in several materials, showed item material is aluminum, also mild steel with zinc plating for everyday shop work. Stainless steel if moisture or road salt is a concern. And we can add yellow zinc or black oxide if your job calls for it. Sizes run from M4 up to M12. Cup depth varies too — deeper cup for thicker panels, shallower cup for tight clearance. If you don’t see your size on the list, just ask. We run small batches all the time.

Why Our Factory Stand Out?

We’re Qimao Metal Manufacturer and produce the product Hex Nut Cup Washer One‑Piece Cold‑Forged for Automotive And Industrial Use by cold heading process, we’ve been cold heading and stamping small fasteners for over twenty years. Most of our machines run custom tooling we designed ourselves to keep the weld centered every time. You won’t find off-center nuts or weak welds here. We test pull strength every shift. Also, we keep common sizes like M6, M8, and M10 on the shelf. Need a non-standard cup depth or a different plating? We can do small batch orders without a big minimum. We don’t use middlemen — you talk directly to the people who run the presses. That keeps prices fair and lead times short. Many of our automotive and trucking customers have stayed with us for over a decade just because we answer the phone and deliver what we promise.
