Our hex jam nuts are a true, solid 651 Silicon Bronze Alloy and comparable to our regular hex finish nuts but thinner. Two jam nuts are generally used at a time, and tightened against one another for a locking effect. Jam nuts are often also referred to as:
- Check Nuts
- Thin Hex Nuts
- Thin Nuts
Need an anti-seize and thread protectant for these nuts? Don't forget to add on some Fair Wind Screw Lube.

I tried in all the marine supply stores and hardware stores in Annapolis to find bronze bolts, washers, and nuts to replace a broken bolt on my stuffing box. I had no luck at all anywhere, even in this boating community. I found Fair Winds Fasteners online and had my stuff in 4 days. A good price and reasonable shipping.
