Product Description
Double-ended studs generally require surface treatment. There are many types of bolt surface treatment, and the commonly used ones are electroplating, blackening, oxidation, phosphating, and non-electrolytic zinc flake coating treatment. However, electroplated fasteners occupy a large proportion in the actual use of fasteners. It is especially widely used in industries and fields such as automobiles, tractors, home appliances, instruments, aerospace, and communications. However, for threaded fasteners, it is not only required to have a certain anti-corrosion ability, but also to ensure the interchangeability of threads, which can also be referred to as screwability here. In order to meet the dual performance of "anti-corrosion" and "interchangeable" required by threaded fasteners in use, it is very necessary to formulate special electroplating standards.
The stud bolts are manufactured according to the GB897-GB901 standard. The materials used are: Q235, 45#, 40Cr, 35CrMoA, Q345D, and the high-strength stud bolts are made of 35#, 45#, 35CrMoA, 25Cr2MoV, 304, 316, 304L, 316L, 2H, 2HM, B7, B7M, B16, B8, 8, B8M, 8M, widely used in electric power, chemical industry, oil refining, valves, railways, bridges, steel structures, automobile and motorcycle accessories, etc. Used in mining machinery, bridges, automobiles, motorcycles, boiler steel structures, hanging towers, long-span steel structures and large buildings, etc.
1. When the main body is large-scale equipment, accessories need to be installed, such as sight glass, mechanical seal seat, deceleration rack, etc. At this time, the stud bolts used at this time are screwed into the main body at one end, and the other end is equipped with a nut after the accessories are installed. , because the accessories are often disassembled, when the main body and the accessories are directly connected by bolts, the main thread will be worn or damaged over time, and it is very convenient to replace it with stud bolts. 2. When the thickness of the connecting body is very large and the bolt length is very long, stud bolts will be used.
