Clearance Spacers

We stock a wide range of mild steel, mild steel zinc-plated and stainless steel A2 clearance spacers. The portfolio includes closed-seam rolled spacers and turned spacers, plus we also provide moulded spacers, which are available in nylon.
Clearance Spacers are normally used to allow two parts of an assembly to be fastened together at a controlled distance from each other. They are fastened with a nut and bolt and are used where the inside diameter of the spacer is slightly larger than the bolt.
