Let’s be honest — most DIY disasters don’t start with a sledgehammer. They start with a fastener. Or more accurately, the wrong fastener.

You’ve built the deck. You’ve oiled the timber. You’ve stood back, beer in hand, and admired your handiwork. But before you declare it finished, there’s one more job that deserves your full attention: the balustrade.

Let’s talk about where marine-grade fasteners belong *off* the water — right in your garage, and more importantly, all over your rig.

If you're tackling a restoration — whether it’s a Holden Monaro, a Mini Cooper, or a crusty old FJ that’s seen better decades — here’s why you need to match your fasteners to the era.

Ever wondered why one bolt holds steady for decades, while another loosens faster than a bloke’s grip on Dry July? It’s not magic — it’s science.

Whether you're building a deck, fixing a boat trailer, or trying to stop your shed door falling off again, the fasteners you use matter.

If you’ve spent more than ten minutes near saltwater with a tackle box in hand, you already know this: the ocean is not kind to anything made of inferior metal.

At Bolt-In Co Sunshine Coast, we stock all kinds of fasteners — from the humble coach screw to the kind of bolt you’d use to keep a tank’s wheels on. Somewhere near the top of the strength food chain? That’d be your Grade 12.9 steel bolts.

If you’re a boatie, you already know: stainless is non-negotiable. You wouldn’t trust your hull to mild steel, so why trust your hardware?

What exactly goes into making this ultra-tough steel?
