Fixaball UNF 9/16" Hex Bolt Set Screws High Tensile 8.8 Zinc BZP

These UNF 9/16" hexagon head fasteners are available as either partially threaded bolts or fully threaded set screws, in high tensile grade 5 steel comparable with 8.8. Each option has a 9/16" UNF thread with 18 T.P.I and a zinc/BZP/Cr3 finish.

Fully threaded set screws are offered in shorter lengths, while the partially threaded bolt options are available in longer sizes. For partially threaded versions, the threaded section is stated as a rule of thumb to be as long as the diameter x 2.5, with the plain shank increasing on longer lengths.
