Fixaball UNC 5/16" Hex Bolt Set Screws High Tensile 8.8 Zinc BZP

Available in a range of lengths, these Fixaball UNC 5/16" hexagon head fasteners are supplied in high tensile Grade 5 steel with a zinc BZP Cr3 finish. The thread specification is 5/16" UNC with 18 T.P.I, with shorter sizes offered as fully threaded sets and longer sizes as partially threaded bolts.

UNC and UNF high tensile standard fasteners are marked with a "5", comparable with metric high tensile 8.8. This range suits applications requiring either a fully threaded hexagon set screw or a part plain shank hexagon bolt, depending on the selected length.
