1. Product Description

DIN931 full threaded hex bolt is a fastener consisting of head and screw. According to the material, the bolt can be divided into iron bolt and stainless steel bolt, that is, hexagonal head bolt (partial thread) - C level and hexagonal head bolt (full thread) - C level.

Hexagonal bolt: A type of fastener consisting of a head and a screw (a cylinder with external threads), which needs to be matched with a nut to fasten and connect two parts with through holes.

This connection form is called bolt connection. If the nut is screwed off from the bolt, the two parts can be separated, so the bolt connection belongs to the removable connection.
