Stainless Steel Square U-Bolts
Dale Fastener Supply is a trusted manufacturer and distributor of 304 stainless steel square U-bolts. As a dedicated square U-bolt supplier, we can accommodate both custom and standard size requirements. Our 304 SS square U-bolts are particularly popular for their excellent corrosion resistance, making them ideal for saltwater environments such as boat trailers, lifts, docks, boathouses, and bulkheads. Beyond marine applications, our square U-bolts are also widely used in heavy equipment projects. We offer same-day shipping for stock U-bolts and provide quick turnaround times for custom orders.
Custom Square U-Bolts
In addition to our standard 304 SS square U-bolts, we also manufacture custom square U-bolts in materials such as carbon steel, A193 B7 4140, and 316 stainless steel, with a range of finishes including Hot Dip Galvanized, Zinc Plated, and Pro-Coat. All U-bolts are produced at our Houston, Texas facility, allowing us to offer quick lead times and competitive pricing. For custom orders, please request a quote today.
Stock bolts have a minimum purchase of $25.
