FLANGE BOLTS
ISO 4162 Small Series Hex Flange Bolts
Small-series hex flange bolts for joints requiring the ISO 4162 head and flange envelope.
Product Overview
The small-series flange head combines a compact external hexagon with an integral bearing face. It can suit machinery and equipment assemblies with restricted space around the head, provided the flange fits the mating feature. Selection should start with the actual head envelope and bearing geometry rather than a generic description of a flange 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.
