FAQ

Is 18-8 stainless the same as 304?
18-8 is the family name for stainless with about 18% chromium and 8% nickel, and 304 is the most common grade in that family. It resists rust in wet and outdoor use but is not magnetic-proof and is not as resistant as 316 in salt water.

Do these come with washers?
No. Stainless square U-bolts are supplied with 2 stainless hex nuts. Stainless washers are sold separately.

How is a square U-bolt measured?
A is the rod diameter and thread, C is the inside width between the legs, B is the inside length from the inside of the top to the end of the legs, and T is the thread length.

Can you make a U-bolt size that isn't listed?
Yes. We custom manufacture square and round bend U-bolts in plain, zinc plated, galvanized and stainless steel. Use the Custom Manufactured U Bolts page to request a quote.
