HEX BOLTS
ISO 8765 Fine Pitch Hex Bolts
Fine pitch hex bolts with a shank for machinery joints requiring a defined fine-thread specification.

Product Overview
Fine pitch hex bolts combine an external hexagon head with a fine-threaded end and a shank. They suit machinery joints where the mating thread pitch is specified and the grip length must be controlled. The finer thread must be identified explicitly in an enquiry because nominal diameter alone does not distinguish it from a coarse-thread bolt.
For an accurate quotation, specify the thread size, nominal length, material requirement and surface finish, together with the intended mating component. Dimensions, inspection requirements and the exact material and finish combination must be agreed before order confirmation.
