At Redmac, we supply a wide range of nuts & bolts, washers, and fasteners suitable for heavy-duty use in construction, agricultural, industrial, and plant machinery. Whether you’re performing essential repairs, building custom assemblies, or carrying out routine maintenance, our nuts and bolts provide the secure, reliable fastening you can trust in tough environments.

Our extensive stock includes standard hex bolts, high-tensile bolts, flange bolts, U-bolts, lock nuts, nyloc nuts, washers, set screws, coach bolts, and more—available in metric and imperial sizes, multiple thread pitches, and a variety of finishes including zinc-plated, black oxide, and stainless steel.

Redmac fasteners are selected for their strength, durability, and resistance to vibration, corrosion, and wear. They are ideal for high-stress applications across all sectors—from securing ground-engaging tools and hydraulic components to general-purpose repairs on trailers, engines, and frames.

We also stock Nuts & bolt kits for specific machine models (including Caterpillar, JCB, Komatsu, and Volvo), making it easier to get everything you need in one go. Whether you’re working on-site or in the workshop, our nuts and bolts are clearly labelled, well-organised, and available in small packs or bulk quantities.
