Product Overview
Product Application
DIN 933 specifies hexagon head fully threaded bolts (Hexagon Head Screws with Thread up to Head) and is the most widely used and common bolt standard in the industrial sector. It is a sister standard to DIN 931 (partially threaded bolts).
The thread on a DIN 933 bolt extends all the way to the base of the head. This means that regardless of the bolt’s length, the entire shank is fully threaded, making it ideal for blind hole installations or applications requiring adjustment of the clamping distance.
