Products Description:

Hexagonal bolt is divided into outer hexagonal bolt and inner hexagonal bolt.This product belongs to the outer hexagonal bolt.This product name is Galvanized Hex Bolt Din 933 Stainless Steel Or Carbon Steel Plain Color,the size is M33,the length is 135mm,the surface treatment of hex bolt is zinc plated,Grade is 8.8,the materials are of high quality carbon steel or stainless steel.Our company also have other main product:nuts,washers,bolts,wedge anchors,and so on.

Screw is commonly known, with external thread can be called "screw".Nuts are usually hexagonal shape, the inner hole for the internal thread. Used with the bolt, the tight related parts. Nuts are commonly known as the standard should be referred to as "nut".The head of the bolt is generally hexagonal, the rod with an external thread.Small screws, flat head, cross head, etc., with a male thread.The actual stud should be called "stud", both ends have external thread, the middle is generally polished rod.The long end of the thread is used to connect to the deep hole, and the short one to the nut.

application

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
