M6 x 1.0mm Nylon Insert Hex Lock Nuts 50Pcs 304 Stainless Steel Locknuts, Hex Drive, Black Oxide by SG TZH

Quality stainless hardware, no issues identified. It did not come with any storage container just a plastic bag, it would be better if it had better packaging, would buy again if needed. This does appear to be real stainless and better quality than what is carried at the local hardware store or home depot

Holding 400w of solar on my rv roof. No wiggles or noises. They fit properly and perform their intended function.

Works as advertised no Problems yet. Look and feels appropriate. Reasonable

The nylon lock gives it a slightly higher profile than I desires, but so would a lock washer. You need threaded holes or conventional nuts with Loctite if height matters

M6x1.00 stainless, does exactly what a locknut should do — threads on clean, locks down solid, no backing off. Bought a pack, needed locknuts, problem solved. If you need M6 stainless locknuts, these are them.

Worked great

Good price
