Nuts & Washers
Custom nuts and washers — hex, lock, flange, nyloc, spring, and special shapes manufactured to your drawing in matching material and finish.
Tailored to Your Specifications
The assortment shown demonstrates our versatility in custom metal manufacturing. From specialized head geometries to high-precision threads, we deliver components that meet the exact requirements of your technical drawings.
A fastener joint is only as reliable as its nut and washer. We produce hex nuts, lock nuts, flange nuts, nyloc nuts, flat washers, spring washers, and fully custom washers — matching your bolts and screws from the same material and finish family so the whole assembly performs as one system.
Our nut and washer lines cover M3 to M64 in DIN, ISO, ANSI, GB, and JIS standards, with plating options engineered for corrosion resistance in demanding environments.
