M12 bolts

M12 bolts are commonly specified for structural steelwork and heavy-duty fixing jobs. They’re suitable for connecting timber, concrete, and metal components. You'll often fit an M12 bolt where a strong, vibration-resistant connection is needed, particularly in load-bearing uses like frame construction or anchoring base plates.

M12 bolts come in a range of materials, such as zinc-plated, stainless steel, and galvanised finishes. Choose between fully threaded or partially threaded styles, with hex heads most common for torque control. When checking M12 bolt dimensions, ensure compatibility with nuts and washers used on-site. Compared with smaller bolt types, M12 bolts offer a higher clamping force, while still being easier to handle than larger diameters used in structural connections.
