Typical Applications
Suitable for equipment maintenance, restoration, brackets, fixtures and mechanical assemblies requiring a fully threaded 9/16" UNF stainless steel fastener.
Installation
Use matching 9/16"-18 UNF nuts or tapped holes. Ensure sufficient thread engagement and check that the screw cannot bottom out in a blind hole before the joint is clamped.
Start the thread by hand and tighten using a correctly fitting 13/16" spanner or socket. Use an appropriate stainless steel anti-seize lubricant where suitable, and follow tightening guidance that accounts for lubrication and the joint materials.
