Most of the embedded parts are metal members, and steel plates and anchoring ribs are preliminarily left in the structure, which can be used to connect the structural members. It can be used as a connecting piece for fixing the post-process. Generally, the embedded parts should be processed according to the drawing, and then the…
Classification of T-bolts The T-bolt is literally known as the shape of the bolt like an uppercase English letter “T”, which is a good name. According to its use, it can be divided into the following types: 1. T-bolt for Hafen channel steel, the most commonly used is 45# steel, cast, quenched and tempered; also…
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…
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…
The nuts are fastener having an internal thread and used in conjunction with a bolt, a mechanical part having an internal thread and used in conjunction with the screw to transmit motion or power. The nut is a part that is screwed together with a bolt or a screw for fastening. All the original parts…
High strength structure bolts High strength structure bolts can be called high strength bolts. High strength bolts are mostly used to connect bridges, rails, high-pressure and ultra-high-pressure equipment. The fracture of these bolts is brittle fracture. High strength bolts are used in ultra-high pressure equipment. Bolts, in order to ensure the sealing of containers, need…
The high strength bolt is the load that can be endured is larger than the ordinary bolt of the same specification. Common bolts are made of Q235 (A3). The material of high strength bolt is 35 # steel or other high quality material, which is heat treated after being made to improve the strength. The…
Flange bolts Flange bolts consist of hexagonal head and flange disc (gasket under hexagonal and fixed hexagonal) and screw (cylindrical body with external threads). They need to be matched with nuts to fasten the parts connecting the two through holes. This connection form is called bolt connection. If the nut is screwed off from the…
A490 Hex Structural Bolt is a form of threaded fastener with an external male thread. Bolts are thus closely related to, and often confused with, screws. A hex cap screw is a cap screw with a hexagonal head, designed to be driven by a wrench (spanner). An ASME B18.2.1 compliant cap screw has somewhat tighter…
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…
