Grade 4.8-12.9 high strength hexagon socket bolts,Galvanized hot dip galvanized hexagon bolts,4.8 Grade Hexagon Head Bolts
Hex bolt: A type of fastener consisting of a head and a screw (a cylinder with external threads), used in conjunction with a nut for fastening two parts with through-holes. This type of connection is called bolt connection. If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection. 1. According to the force mode of connection, there are ordinary and reaming holes. Bolts for reaming holes should fit the size of the holes and be used when subjected to transverse forces. 2, according to the head shape of hexagonal head, round head, square head, countersunk head, and so on, the general countersunk head is used in the requirements of the connection after the surface is smooth without protrusions, because the countersunk head can be screwed into the parts. Round heads can also be screwed into parts. The tightening force of square head can be larger, but the size is large. The hexagonal head is the most commonly used.Handan Chang Lan Fastener Manufacturing Co., Ltd. formerly Yongnian Tiexi Changhe fastener factory was large-scale standard fastener manufacturer in Yongnian District.
