Service HotlineIn 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.
Knurled copper nut, the specification is M5X8X12, the outer circle is 8.0MM, and the height is 12MM. Material: C3604 (ROHS PASS) brass. The thread still guarantees 6H accuracy. This knurled copper nut is used in power tools. Unlike other knurled copper nuts, the diamond pattern of this knurled copper nut is located in the middle of the product, and the diamond-shaped mesh knurled wheel edge The large outer circular step surface is rolled out of diamond-shaped flowers.
Screw (English a screw) refers to the parts used in construction machinery. It is a kind of threaded parts with sharp ends such as nails, small cylindrical or conical metal rods, with grooved or dimpled heads, and used alone. . The detection of the screw should start from the wire of the screw. The quality of the precision screw is directly related to the wire that produces the screw. A good screw wire will open the screws more beautifully. What screw head burst, what thread is bad. Good screw wires generally do not find this situation.
Semi-round head plastic screws have high-quality characteristics such as insulation, non-magnetic, corrosion resistance, beautiful appearance, and never rust, and modified engineering plastics, its strength and impact resistance are comparable to those of metals. The plastic screws we often say are commonly known as nylon. After adding 30% glass fiber to the screw, its mechanical properties are far superior to ordinary nylon. The materials used for the dome head plastic screws are becoming more and more diverse, the performance is constantly improving, and the application fields are becoming wider and wider. 1. Medical equipment industry (insulation, non-magnetic, environmental protection, anti-interference, make medical equipment safer to use) 2. Wind power industry (isolation and insulation of chassis circuit PCB boards) 3. Aerospace industry (electronic equipment Insulation, anti-interference) 4. Office equipment industry (never rust, beautiful and practical) 5. Petrochemical industry (high temperature resistance, chemical resistance, corrosion resistance, prolong equipment life) 6. Electronics industry (insulation, anti-interference) , light weight) 7. Communication industry (insulation, non-magnetic, safety) 8. Ship industry (acid resistance, alkali resistance, corrosion resistance, extended service life), etc... .
The purpose of Guangdong Yueluo Hardware Industry Co., Ltd. is to overcome the above shortcomings and provide a limit screw. The technical scheme of Guangdong Yueluo Hardware Industry Co., Ltd. is realized in the following way. Its structure is composed of screws, hexagonal copper posts and limit necks. The left end of the limit neck is open, the hexagonal copper column is communicated with the inside of the limit neck, and the inside is provided with screw threads. The design length of the screw thread in the hexagonal copper column is 1/3-2/3 of its own length. The advantages of Guangdong Yueluo Hardware Industry Co., Ltd. are (10), which can effectively prevent the problem of poor memory contact caused by the increase of the deformation of the motherboard due to the warping and deformation of the motherboard during installation and fixation, and can effectively control the deformation. effect.
We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: building formwork pins, multi-tooth locking, GB873 rivets, internal tooth locking washers and other products, we can provide you with suitable fasteners Firmware Solutions.
