M20 Stainless Steel Bolts

Stainless steel M20 bolts are designed for heavy-duty structural and industrial fixing where strength, durability and corrosion resistance are essential. Commonly used in steelwork, machinery, timber construction and large assemblies, M20 fasteners provide the load capacity and reliability needed for demanding applications.

All M20 (20mm) bolts use a standard metric coarse thread (2.5 mm pitch), ensuring compatibility with standard M20 nuts and washers.

At Fixabolt, our M20 stainless steel bolts are trade-grade fasteners supplied in A2 (304) stainless steel, offering dependable performance for both indoor and outdoor use.
