Nuts
Hex Hi Nuts
A hex hi nut is a tall hexagonal nut with more height and thread engagement than a standard hex nut. The added height spreads load and reduces the chance of thread stripping in softer base materials.
Used where extra thread engagement is needed, such as jigs, fixtures and machinery assembled and disassembled often. Bought by machine builders and maintenance teams.
