Stainless Steel A2-70 316L Hex Head SEM Combine Machine Screw

Stainless Steel A2-70 316L Hex Head SEM Combine Machine Screw

  Stainless Steel Hex Head Sem Combine Bolt With Washer,Stainless steel hexagonal bolt consists of head and screw. There are two kinds of materials, one is iron, the other is stainless steel. Stainless steel materials are divided into 304, 316, 316L and other materials. As a Chinese manufacturer, stainless steel hexagonal bolts have a wide range of materials and thread types, which can be produced according to customer requirements. Customized drawings are provided by users. The meaning of bolt performance grade is international general standard. Bolts of the same performance grade, regardless of their material and source, have the same performance. Only performance levels can be selected in the design. Strength grade is 8.8, strength grade is 10.8, that is, the shear stress level of bolts is 8.8 GPa and 10.8 GPa. Our company has been producing and operating fasteners for many years, exporting foreign trade for many years, and our products are exported to Europe, America and other countries. Fastener types are complete. Welcome to consult.

Application:

1. There are common and hinged holes according to the way of force acting on connections. The bolts used for hinged holes should match the dimensions of holes and be used when subjected to transverse forces.
2. The countersunk heads with hexagonal head, round head, square head, countersunk head, etc. are generally used in places where smooth and protruding surface is required after connection, because countersunk heads can be screwed into parts. Round head can also be screwed into parts. The tightening force of square head can be larger, but the size is large. Hexagonal head is the most commonly used.
In addition, in order to meet the need of locking after installation, there are holes in the head and in the rod. These holes can keep the bolt from loosening when it is vibrated.
Some bolts with no thread should be thin, called small waist bolts. This bolt is conducive to the coupling of forces.
The steel structure has special high-strength bolts. The head will be bigger. The size will also change.
There are also special uses: T-groove bolts, machine tool fixtures used most, special shape, head side to cut off. Foot bolts used for machine and ground connection fixed, there are many shapes, U-shaped bolts, such as the aforementioned and so on.
There are special studs for welding, one end with thread and one end without thread, which can be welded on parts, and the other side can be directly screwed nuts.
