Fasteners
High-tensile bolts, nuts, studs & washers in stainless, carbon and alloy steel for structural and flanged joints.
Product Overview
Our fastener range covers the hardware that completes a flanged or structural joint — hex bolts, studs, nuts and washers in grades matched to the pressure and temperature demands of the connection.
Coatings from black oxide to hot-dip galvanising are available for corrosion protection in outdoor, marine and buried service.
