Fasteners Direct have a large variety of nuts and bolts in stainless steel, galvanised and zinc. Our experiences staff can help you choose the best fasteners depending on the application you require it for.  We can also source nuts and bolts for unique or one-off projects to ensure your job is completed on time with quality fasteners.

Stainless steel: Stainless steel nuts and bolts have a high resistance to corrosion. This resistance to corrosion is due to the naturally occurring chromium-rich oxide film formed on the surface of the steel. Although extremely thin, this invisible, inert film is tightly adherent to the metal and extremely protective in a wide range of corrosive media. The film is rapidly self repairing in the presence of oxygen or damage.

Galvanised: As a general rule, nuts and bolts, and washers down to 8 mm diameter can be galvanised and a wide range of threaded components can now be processed using special equipment. For ISO metric fasteners, the galvanising of one thread either internal or external requires an extra clearance of four times the coating thickness. In practice, it is normal for standard bolts from stock to be fully galvanised, but for nuts to be galvanised as blanks and then tapped up to 0.4 mm oversize with the threads then lightly oiled. When assembled, the nut thread is protected by contact with the coating on the bolt. Even after many years of service, galvanised nuts can readily be unfastened even though the threads have never been galvanised.
