U-bolts manufactured in the UK by Graphskill Ltd using good quality European steel (Mill traceable)

British Standard U-bolts for British Standard Pipes Zinc Plated Mild Steel

Conforms to British Standard 3974 PART 1: 1974 Fig 11A. Gripped U-bolt (Anchor)

Use where it is necessary to grip the pipe in all directions

Includes two nuts per leg

BZP - Bright Zinc Plated - A 3 micron plating is applied to the steel to give a shiny finish. Although it does afford some protection this is best suited to an indoor use

Although designed for British Standard Pipe Size, they can obviously be used wherever the dimensions are suitable for your application

Our manufacturing tolerances are + / - 1 mm

We use roll threading so the diameter of the bar is usually less than the thread size. Please ask if unsure
