Product Description
5/8" UNC A2 Stainless Steel Fully Threaded Hex Set Screws
These 5/8"-11 UNC hexagon head set screws are manufactured from A2 stainless steel and feature a fully threaded shank. Also known as fully threaded hex bolts, they are suitable for use with matching UNC nuts or tapped holes.
The A2 stainless steel construction provides corrosion resistance for general engineering, maintenance and equipment assembly. Each hexagon head takes a 15/16" spanner or socket.

Typical Applications
Suitable for brackets, machinery, equipment repairs, restoration and general engineering assemblies requiring 5/8"-11 UNC stainless steel fully threaded fasteners.
Installation
Use with compatible 5/8"-11 UNC nuts or tapped holes. Choose a length that provides sufficient thread engagement and tighten to the assembly specification. Keep threads clean and use an appropriate anti-galling lubricant where required, accounting for its effect on tightening torque.
Ordering
Select the required length and pack quantity from the available options. Length excludes the hexagon head. Check that the mating thread is 5/8"-11 UNC before ordering.
