Macsim Hex Bolt and Nut 3/8" x 5" Zinc Plated

When you're bolting a frame together or hanging a bracket, a bolt that turns up with its own nut saves you hunting through the drawer for a partner. This 3/8 inch one comes matched and ready.

It's a Grade 4.6 zinc-plated bolt, made for everyday framing and bracket work where you want a solid, dependable fix rather than high-tensile strength. The hex head takes a standard spanner or socket, so it pulls up clean and tight.

Worth knowing before you buy. The zinc plating handles moisture indoors and under cover, but for anything coastal or out in the weather long-term, go galvanised instead. It's imperial sizing too, so it matches older fittings and existing holes.

Full sizes and specs are in the tabs below. If you're not sure which length you need, pop in or give us a call and we'll sort it out.
