Screw Specifications

Screw head table

self-locking screw comprises a screw main body, a metal screw head is arranged on the upper part of the screw main body, a thread is arranged in the middle part of the screw main body, an interference groove is arranged on both sides of the upper part of the screw main body, and the line of the interference groove is arranged. The included angle is 280-364° with the horizontal line. The bottom of the screw body is provided with an elastic chuck, and the elastic chuck includes an optical axis and a conical head. Guangdong Yueluo Hardware Industry Co., Ltd. Guangdong Yueluo Hardware Industry Co., Ltd. adopts the design of elastic collet, and the screw is provided with threaded segments and interference grooves, so that during the screwing process, the interference groove of the optical axis between the two threaded segments is formed along the screw. The axial elastic force achieves the effect of reliable self-locking, which is easy to use and has high tuning efficiency.

The t-bolt can be directly put into the groove of the aluminum profile. It can be automatically positioned and locked during the installation process. It is often used in conjunction with the flange nut. profiles to choose from. T-bolts are movable anchor bolts. Bolt: A mechanical part, a cylindrical threaded fastener with a nut. A type of fastener consisting of a head and a screw (a cylinder with an external thread) that needs to be matched with a nut to fasten and connect two parts with through holes. This form of connection is called a bolted connection. If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection. There are hexagonal head, round head, square head, countersunk head and so on. Among them, the hexagonal head is commonly used. Generally, the countersunk head is used in places where the surface is required to be smooth without protrusions, because the countersunk head can be screwed into the part. Round heads can also be screwed into parts. The tightening force of the square head can be larger, but the size is large.

Hexagon head does not come out

Equipment that needs to be maintained at high altitude or under complex working conditions requires screw loss prevention design. Although traditional captive screws can achieve the purpose of preventing falling off, because the diameter of the screw is smaller than the major diameter of the thread, it is difficult to match the gasket, and the gasket will be eccentric, which is easy to install. Scratch the surface of the product, affecting the corrosion resistance and appearance of the product.
