M12 Carriage Bolt & Nut (75mm, Box of 25)

Durable Galvanised Carriage Bolts

M12 Carriage Bolt & Nut (75mm, Box of 25) provides a strong and reliable fixing option for timber, fencing and structural work. Each bolt comes with a matching nut and features a smooth domed head that gives a neat and secure finish. The hot dipped galvanised coating offers excellent protection against rust, which supports long-term outdoor use.

Made for Timber and Structural Fixing

The bolts suit a wide range of projects, including fence posts, gates, timber frames and heavy-duty yard work. The 75mm length provides a firm fixing point without excess protrusion, and the M12 diameter adds strength where it is needed most. You can use these bolts with softwood, hardwood and pressure-treated timber. M12 Carriage Bolt & Nut (75mm, Box of 25) is ideal for both trade and DIY installations that require dependable performance.

Easy to Install

The square shoulder under the head helps grip into the wood as the nut tightens. This prevents rotation and makes installation easier with standard tools. The coating also reduces thread friction, supporting smooth tightening and removal when required. You can use these bolts for gates, fencing rails, stable fixtures and general building tasks where a secure fixing is essential.

Strong and Long-Lasting

Hot dipped galvanising creates a thick protective layer that resists rust and moisture. As a result, the bolts perform well in agricultural, equestrian and outdoor environments. The box of 25 gives good value for larger projects and ensures you have consistent hardware on site. The bolts work well with brackets, plates and timber joints that need a reliable mechanical fixing.
