Product Description

Selecting Your Bolts
Select the required length and pack quantity from the available options. Allow for the combined thickness of the components and washers, together with sufficient engagement in the matching nut or tapped hole.
Check the thread before ordering. These bolts use a 1"-8 UNC thread and are not interchangeable with 1" UNF or metric fasteners.
If a particular threaded length or head dimension is essential, please contact us to confirm before ordering. Use a correctly fitting spanner or socket and tighten to the equipment or joint specification.
