Product Description
5/8" UNC Grade 5 High Tensile Zinc Plated Steel Hex Head Bolts
These 5/8" UNC hexagon head bolts are manufactured from Grade 5 high tensile steel with a bright zinc plated finish. They feature an 11 TPI coarse thread and a partially threaded shank for assemblies requiring a plain section beneath the head.
Available in lengths from 2 1/4" to 5 1/2", these bolts are suitable for machinery, brackets and general engineering assemblies using matching imperial threads. The zinc plating provides a protective finish that helps resist corrosion.

Selecting Your Bolts
Select the required length and pack quantity from the available options. Use with matching 5/8"-11 UNC nuts or tapped holes and check that the plain shank and threaded section suit the joint.
Allow for the combined thickness of the components and washers, together with sufficient thread engagement. These UNC bolts are not interchangeable with 5/8" UNF or metric fasteners.
Use a correctly fitting spanner or socket and tighten to the equipment or joint specification.
