Are lock nuts reusable?
All-metal lock nuts can often be reused. Nylon insert lock nuts may lose holding strength after repeated use.
What is the main difference between a standard nut and a lock nut?
Standard nuts fasten components together but can loosen under vibration. Lock nuts have added features, like nylon inserts or deformed threads, that resist loosening.
Are custom sizes or stainless steel U-bolts available?
Yes. Marsh Fasteners provides both standard and square U-Bolts stainless steel, with bulk ordering options available. Contact us for tailored solutions to fit your specific application
Do U-bolts come with nuts and washers?
Nuts and washers are sold separately. We offer compatible 18-8 and 316 stainless steel hex nuts, lock nuts, and flat washers to match your U-bolt size and threading requirements.
Can I use U-bolts for boat trailers and marine equipment?
Yes. Stainless steel U-bolts, especially those made from 316, are excellent for boat trailers, winch posts, guide poles, leaf springs, and other marine hardware where corrosion resistance is critical.
