Stainless Steel Coach Bolts

Stainless steel coach bolts, also known as stainless steel carriage bolts or cup-square bolts, earn their name from the unique square neck beneath the head. This square neck isn't just for show - as you tighten the bolt from the underside, that square neck digs into the wood, creating a grip that's as solid as your reputation on the job site!

No more worries about coach bolts wiggling loose over time. The square neck locks in, putting a stop to any rotation during assembly. That's the kind of reliability tradespeople crave when they're crafting something that needs to stand the test of time.

And let's talk style - stainless coach bolts aren't just tough; they've got a domed head that not only looks good but also keeps things smooth. No snagging on your gear or clothes, just a slick and secure fastening solution.

Whether you're working on wood projects, construction gigs, or tackling structural masterpieces, coach bolts can be your go-to.
