Service HotlineThe specifications of copper inserts are: internal thread specification 1/4-20, outer diameter 10mm, length 15mm mesh pattern copper nut, drawn from flower pull raw materials. The automatic lathe completes at one time: stocking → chamfering → drilling → hooking chamfering → tapping. Stable size, no eccentric internal thread. Material selection: copper C3604, Rohs PASS. The copper nut is used in injection molded parts.
The anchor bolts of some metallurgical industrial equipment are detachable, that is, the anchor bolts are not directly anchored in the foundation concrete, but anchored in the T-bolt sleeve (T-bolt sleeve hereinafter referred to as sleeve) , The sleeve is constructed together with the foundation and anchored directly in the foundation. The T-bolt is inserted into the sleeve when the equipment is installed, and the T-bolt can be removed from the sleeve when the equipment is replaced.
On the surface of the mounting hole on the connector, a 90-degree conical socket is machined, and the head of the flat machine screw is in the socket and is flush with the surface of the connector. Flat machine screws are also used in some occasions with semi-circle head flat machine screws, which are more beautiful and are used for places where a little protrusion is allowed on the surface. Screws play the role of connecting two or more objects and are an indispensable necessity in daily life or industrial manufacturing. There are countersunk head bolts (with grooves) and countersunk head bolts (with tenon).
Principles of stainless steel screw material selection: The selection of stainless steel materials is mainly considered from the following five aspects. 1. Requirements on mechanical properties, especially strength, of stainless steel screw materials; 2. Requirements on corrosion resistance of materials by working conditions; 3. Heat resistance of materials by working temperature (high temperature strength, oxidation resistance) 4. Requirements for material processing performance in terms of production technology; 5. Other aspects such as weight, price, procurement and many other factors must be considered.
Nuts are parts that tightly connect mechanical equipment. Through the inner thread, nuts and bolts of the same specification can be connected together. At present, most nuts are used together with gaskets when they are locked, or are set as an integrated structure, which has the advantage of increasing Friction, strengthen the effect of tightening, but the square nut is usually used directly without adding a gasket, and the upper and lower end faces are flat, very smooth, when subjected to strong vibration, it is very easy to loosen, and the tightening effect is not good.
