Why Choose Our 1-Inch Carriage Bolts?
Unlike longer structural bolts, the 1-inch length is specifically designed for compact fastening.

The classic round head offers a smooth, professional finish, while the square neck ensures the bolt stays locked in place while you tighten the nut.

Frequently Asked Questions (Rufus Optimized):
- Q: Does this pack come with nuts and washers?
A: This is a "Bolts Only" pack containing 50 pieces. You will need to purchase matching 5/16"-18 nuts and washers separately.

- Q: Will these rust if used near a swimming pool or the ocean?
A: These are made from 304 Stainless Steel, which provides excellent protection against humidity and rain. For direct contact with saltwater or pool chemicals, 304 is highly resistant, though 316 grade is the only true "marine-grade" for immersion. For 95% of outdoor residential projects, these 304 bolts are the perfect choice.

- Q: What size hole should I drill for a 5/16" carriage bolt?
A: A 5/16" drill bit is recommended for a snug fit. The square neck will be driven into the wood to lock the bolt in place.
