U-bolts
Galvanised U-bolts are available in various shapes (round and square) and sizes for general clamping applications, especially in outdoor and marine environments, due to their corrosion resistance.
Product Information and Types
Finish: Galvanised U-bolts are typically finished using an ElectroGal process, which provides superior corrosion resistance for outdoor and marine applications compared to standard zinc plating.
They come in two main shapes:
Round: Designed for securing round objects like pipes or round axles.
Square: Intended for square profiles such as trailer drawbars or chassis rails.
Materials: Generally made from steel, they often come with ElectroGal nylock nuts and washers to ensure a secure and rust-resistant fit.
Reviewers suggest replacing Nyloc nuts when reusing U-bolts, as Nyloc nuts are one-use-only for optimal safety.
Sizing: U-bolts are measured by their internal width (ID) and internal length/height (L). Common sizes range from 1/2-inch (39mm Round ID) to larger 100mm square options and beyond, with measurements often referring to the nominal bore (NB) of the pipe they are designed to fit.
