Stainless Steel Cap Nuts

Our stainless steel cap nuts are integrally cold forged, combining hexagonal nut body and spherical protective cover into one piece. The dome cover effectively shields exposed bolt threads from oxidation, collision scratches and external dirt, while delivering a sleek decorative appearance for assembly surfaces.

Manufactured from premium 304 stainless steel, these nuts possess outstanding resistance to moisture, acid and corrosion, making them suitable for damp and outdoor service environments. Each internal thread is precision tapped to match standard bolts tightly, ensuring smooth screwing and reliable locking performance without loosening during operation.

We maintain abundant stock of standard metric specifications. Customized production is supported according to your drawings, including adjustable thread size, overall height and dome diameter. Widely applied in furniture assembly, mechanical equipment installation, handrail engineering and architectural decoration, our cap nuts provide both functional fastening and aesthetic optimization.

All items undergo strict dimensional and surface inspections before delivery. As a professional cold forging fastener manufacturer, we offer competitive wholesale pricing and complimentary sample testing for global purchasers.
