Overview
ISO 4014 is a dimensional standard for metric hexagon head bolts with partial threading. It is commonly used when a bolt requires a defined unthreaded shank portion beneath the head. The standard helps define key dimensional characteristics such as thread diameter, nominal length, head dimensions, shank length, and product grade. It is typically referenced together with material, mechanical property, coating, and inspection requirements. When sourcing ISO 4014 bolts, the standard alone is not enough to fully define the part. The request should also identify the required diameter, length, thread pitch where applicable, material, property class, finish, quantity, and certification requirements.
