Stainless Steel Nut & Washer Set M12 for Curtain Wall Hardware & Fixing

Stainless Steel Nuts & Washers for Curtain Wall Hardware

Stainless steel nuts and washers for securing curtain wall fittings and assemblies. Supplied in corrosion-resistant SS304 / SS316 with clear size marking, the set gives installers a matched pair of fasteners that hold spider fittings, glass clamps, brackets and tension rod ends together without mixing grades on site.

The M12 set belongs to our stainless steel fixing hardware range and is used wherever a bolted connection has to be completed with a nut and a washer of the same material and thread. Keeping nuts and washers in the same grade as the bolt prevents galvanic reaction and keeps the visible facade hardware looking uniform.

Installation & Usage

The washer is placed against the contact face of the fitting, the nut is started onto the bolt by hand to avoid cross-threading, and then tightened evenly until the assembly is secure. We recommend checking that the threads are clean before assembly, and fitting a washer under the nut wherever the design calls for it. Site staff should avoid mixing stainless nuts with mild steel bolts so that corrosion performance stays consistent across the whole facade.

Quality Assurance

Every nut and washer is 100% inspected before shipment for thread accuracy, dimensions and surface finish. Material test certificates are available on request to support project documentation and specification approval.
