1. Product Description

A bolt is a class of fastener consisting of a head and a screw (cylindrical body with external threads), used in conjunction with a nut for fastening two parts with through-hole.This form of connection is called bolting.If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection.The anchor bolt is a form of bolt connection. Only the nut part can be removed after assembly. The screw part is fixed together with the concrete base material in some form and cannot be separated.From the manufacturer's point of view, it may be that the screws and wires we use are of poor quality, or it may be that the hexagonal inner bolt pier is beaten out, and after the teeth are rubbed, they are electroplated directly, without being taken to harden them.From the customer's perspective, it may be that when the customer USES the hexagon bolt, the hexagon spoon USES too much force when acting on the head of the hexagon bolt.Or hexagon key and hexagon bolt inside six head depth in various aspects.
