Description
Overview:
The M12 x 90 Zinc Plated 8.8 Steel Bolt is a high tensile hex head bolt for strong, reliable fastening in construction, plant, automotive, electrical, and general engineering tasks. Made from 8.8 grade carbon steel, it offers a high strength-to-size ratio, with a typical minimum tensile strength of 800 MPa and yield strength of 640 MPa. The bright zinc plating provides added corrosion resistance for indoor and outdoor use in UK conditions. Conforming to DIN 931, this is a part-thread hex bolt designed for use with standard M12 nuts and washers. The 90 mm length suits through-bolting, bracketry, frames, engine mounts, and machinery assemblies where a robust clamping force is needed. Supplied in a pack of 25 under MPN 955 479 to keep projects moving and spares organised.
