Without a doubt, they are the oldest known method of metal joining, dating back as far as the earliest use of malleable metals, for example: the Bronze Age Egyptians used rivets to attach six wooden sectors to the outer lines of a slotted wheel Riveted and fastened together. After the Greeks successfully cast large statues in bronze, they then used rivets to rive the parts together. With the progress of the times, there are more and more types of rivets, but traditional rivets have connection strength. Insufficient problem, so a new rivet is needed to solve the above problem.
Screws can be divided into machine screws, self-tapping screws, drill-tail screws, wallboard screws, fiberboard screws, wood screws, hexagonal wood screws, non-prolapse screws, combination screws, miniature screws, furniture screws, and electronic screws. Divided into 1. Hexagon head (hexagon head) 2. Hexagon head with flange (hexagon head with flange) 3. Square head (square head) 4. T head (hammer head) 5. Oblate head mushroom head ( truss head) 6. cylindrical head (cheese head) 7. round head (round head) 8. pan head (pan head) 9. countersunk head (flat head) 10. raised countersunk head (oval according to the groove type) Can be divided into 1. Philip 2. Ten / one word 3. One word 4. Inner triangle 5. Inner corner square 6. Cross 7. Rice word 8. Flower shape 9. Plum shape 10. Flower shape one word 11. Special shape 12. Inside Hexagon
The core rivet is a new type of riveting fastener that is very convenient for riveting. It can show its unique advantages in a relatively small space or in an environment where there is no rivet gun or a rivet gun cannot be used. Two or more connected parts can be riveted successfully by hitting the mandrel on one side with a hammer or other utensils. Core rivets can be divided into oblate head core rivets and countersunk head core rivets according to the shape of the brim of the nail cap. According to different material combinations, they can be divided into all aluminum core rivets, aluminum steel core rivets, and all stainless steel core rivets. Rivets, steel rivets, aluminum stainless steel rivets, plastic rivets, etc. Core rivets do not have to be riveted with manual riveting guns or pneumatic riveting guns like blind rivets. They have better riveting and convenience, and can be widely used in the riveting of various connected parts.
Building aluminum alloy formwork is a new type of building formwork, which conforms to the four sections and one environmental protection policy. It is economical, fast, high-quality and environmentally friendly. Its application is of great significance to building energy conservation and environmental protection. The aluminum template is filled with aluminum template pins. However, the pins in the prior art have low connection strength during use, which is likely to cause the hole to be repaired weakly.
Guangdong Yueluo Hardware Industry Co., Ltd. provides a nut provided by Yueluo, which includes an internal thread. is an arc curve. Compared with the nut of the same type, the normal pressure and friction force of the nut are increased, the thread is not easy to loosen, and the bolt and nut are in surface contact, so it is not easy to cause stress concentration and local material yield, which effectively improves the tightening force of the bolt and nut. Stability, increase fastening reliability.
We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: B18.5 bolts, extended hexagon screws, motorcycle screws, sets of complete extended screw nuts and other products, we can provide you with suitable products for you Fastener Solutions.
