Service Hotlineself-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.
Stud, also known as double-ended screw or double-ended stud. It is used to connect the fixed link function of the machine. The stud bolt has threads at both ends, and the screw in the middle is thick or thin. Generally used in mining machinery, bridges, automobiles, motorcycles, boiler steel structures, pendant towers, long-span steel structures and large buildings.
In order to achieve the above purpose, Guangdong Yueluo Hardware Industry Co., Ltd. discloses a tamper-proof nut, which includes an upper part, a lower part, and an inner threaded hole penetrating the upper part and the lower part. The cross section of the inner threaded hole is circular, so the The lower part is an equilateral triangle cylinder, and the apex of the equilateral triangle cylinder has an arc structure, and the arc structure includes a left arc part and a right arc part with the angle bisector as the center of symmetry, and the lower part has an arc structure. A tamper-proof portion protruding from the lower surface is formed, and the tamper-proof portion is arranged at the left arc portion or the right arc portion.
Wire cutters are widely used tools in electromechanical and other industries, and rivets are widely used standard parts, especially in the manufacturing or maintenance process of the electromechanical industry. Because the currently used wire cutters are mostly used to cut finer steel wires or various wires and twist small screws and nuts. In the process of work, rivets of various specifications are often encountered temporarily. For example, suitable rivets cannot be found at the scene, or other replacements will cause inconvenience to the work, which not only affects the output, but also affects the quality.
Plastic tree rivets are also called inverted tooth plastic rivets, also known as Christmas tree plastic rivets. The toothed flakes have good elasticity and can be directly manually pressed and installed in the round holes of the interference assembly. The toothed flakes can be installed according to the actual thickness and size. It can be fixed by self-adjustment. The design of the inverted tooth type is that the rivet is firmly fixed to the installation surface after installation, and it is not easy to be pulled out. It is suitable for fixing between soft materials such as foam, wood, rubber, and automobile interiors. Plastic tree rivets have excellent insulation, fire resistance, non-magnetic, heat insulation, light weight, high temperature resistance, high strength, corrosion resistance, and are widely used in various industrial fields.
