Heat treated high strength fasteners are conditioned according to technical requirements. Heat treatment quenching and tempering is to improve the comprehensive mechanical properties of fasteners to meet the required tensile strength and yield strength ratio of products. Heat treatment process has a vital impact on the internal quality of high-strength fasteners, especially its internal quality. [...]
How are the bolt heads and threads processed? The forming of bolt head adopts cold heading plastic processing. Compared with cutting processing, the metal fibers are continuous along the shape of the product without cutting in the middle, which improves the strength of the product, especially the mechanical properties. Cold upsetting process includes cutting and [...]
Fasteners Classification and Characteristics There are many kinds of fasteners. According to their names, fastener can be divided into seven basic categories: bolts, screws, nuts, rivets, pins, welding nails and washers. Bolts include external hexagonal bolts, flange bolts, double-headed bolts, anchor bolts, U-shaped bolts, live bolts, carriage bolts, etc. Nuts include hexagonal nuts, cap nuts, [...]
At present, the development prospects of high strength fastener are good, but there are still some problems in domestic high-strength fasteners,following we will discuss about them. 1. Guarantee the load and the wedge load is unqualified. Guaranteed load and wedge load are the key items in the assessment of the mechanical properties of the product [...]
What can be used for fastener products? In fact, the standard parts are a type of mechanical parts that are used for fastening and are widely used. A wide variety of fasteners can be found on a variety of machinery, equipment, vehicles, ships, railways, bridges, buildings, structures, tools, instruments, meters and supplies. It is characterized [...]
Process Flow of High Strength Bolt: The process of nickel-phosphorus plating for high strength bolts consists of three parts: The first part is the pretreatment process, including pre-plating precision and appearance inspection of high strength bolts, manual degreasing, soaking degreasing, pickling, electroactivation and flash nickel plating. The second part is the process of electroless nickel [...]
