HEX BOLTS
ISO 8676 Fine Pitch Fully Threaded Hex Screws
Fully threaded fine pitch hex screws for assemblies with a specified matching internal thread.
Product Overview
This hexagon-head family uses a fine pitch thread along the working shank, subject to the specified thread runout. It is useful where the joint requires adjustment of grip or engagement over a longer threaded portion. Buyers should distinguish it from a partially threaded bolt and identify the exact mating pitch before ordering.
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.
