Fully Threaded Hex Bolts GB70.1 Half Threaded Carbon Steel Structural Heavy Hex

Products Description:

Six angle bolt: a fastener consisting of two parts, the head and the screw (the cylinder with external thread). It needs to cooperate with the nut to fasten and connect two parts with through holes.

This form of connection is called a bolt connection. If the nut is swirled down from the bolt, the two parts can be separated, so the bolt connection is a detachable connection.

According to the shape of the head six head, round, square head, countersunk head, and so on in connection to the smooth surface without protruding place head heavy, because the countersunk head can be screwed onto the parts. Also can be screwed into the round parts. With the tightening force can be bigger, but the large size six. The head is the most commonly used angle

In order to meet the needs of locking after installation, there are holes in the head, and the rod has holes. These holes can make the bolts free from loosening when they are vibrated.

Some bolts are not thread rod to do fine, is conducive to the slender waist bolt. The bolt connection under variable force

Advantage:

Any difference between the six hexagon head bolts can meet the specifications of fasteners, some high-tech equipment has strengthened the bolt parts processing technology, such as Chinese aviation equipment for bolt quality requirements are higher, because of the high quality of bolts can reduce the equipment failure rate and maintenance time, so derived tin plating process. Tin is a silver white metal with no poison and excellent weldability and extensibility. Therefore, it is widely used in the fields of electronics, food, automobiles and so on. The tin plating process of the six angle head bolts is classified by the pH value of the bath, which is divided into two kinds, the acid bath process and the alkaline tin plating process.
