Spacing Screws are used to obtain a precise weld gap between pipes or fittings. Spacing Screw assemblies are available for steel and stainless steel applications. When ordering Spacing Screws, one Spacing Screw should be ordered for each Jackbar and one should be ordered for the Main Block.

Spacing Screws, when mounted to the Jackbar and Main Block, provides a precise and simple way to hold a weld gap between pipes or pipe and fitting.
