Service HotlineWhen using ordinary hexagon head bolts or ordinary T-bolts with the oval groove structure, the bolts need to be inserted from the back of the groove. When the bolts cannot be inserted from the back of the groove due to the structural limitations of the steel base or the platform itself, it is often necessary to open the installation surface. Large diameter hand holes allow for easy mounting of bolts, which weakens the inherent strength and rigidity of a steel base or platform.
Cylindrical pins are widely used, and they are usually provided with matching pin holes. For the tails of cylindrical pins exposed outside the pin holes, they usually do not have a guiding function, which cannot meet the needs of quick installation of workpieces.
Fasteners include: bolts, studs, screws, nuts, washers, pins. Locking or seizure often occurs on fasteners of stainless steel, aluminum alloy and titanium alloy materials. These metal alloys themselves have anti-corrosion properties. When the surface is damaged, a thin oxide layer will be formed on the metal surface to prevent further rust. When the stainless steel fastener is locked, the pressure and heat generated between the teeth will destroy the oxide layer, causing blockage or shearing between the metal threads, and then the phenomenon of adhesion occurs. When this phenomenon persists, the stainless steel fasteners will be completely locked and can no longer be removed or continued to lock. Usually this series of blocking_shear_adhesion_locking takes place in just a few seconds, so the correct understanding of the use of this type of fasteners can prevent this phenomenon.
double-headed pin puller includes a slider hammer and a sliding rod, two ends of the sliding rod are respectively provided with different types of pin-pulling parts, the pin-pulling parts are threadedly connected with the sliding rod, and the sliding rod is also provided with There is a sliding rod limit block, and the sliding rod is slidably connected with the slider hammer. The double-headed pin puller can install two types of pin-pulling heads at the same time, and can pull out two different types of pins. It is easy to use and has high work efficiency. Disadvantage: Single function, cannot be used to install pins.
nut is a connecting nut, a part that is screwed together with a bolt or connecting screw for fastening, and a component that must be used in all production and manufacturing machinery. There are many kinds of nuts, we commonly have standard, German standard, British standard, American standard, Japanese standard nuts. According to different materials, nuts are divided into carbon steel, high strength, stainless steel, plastic steel and other types. According to the product attributes, the corresponding standard numbers are divided into ordinary, non-standard, standard, new standard, American system, British system, and German standard. Different sizes, unequal threads are divided into different specifications. The general standard and German standard are represented by M, and the American system and the British system are represented by fractions or #. The specification nut is a part that tightly connects the mechanical equipment. Only through the inner thread, the same specification nut and screw can be connected together. The anti-loosening of the screw has always been the intersection of people's attention. The anti-loosening of the nut is of great significance to the current life, because it directly affects the service life of the machine. Therefore, it is also very important for people's life safety. Technicians can achieve the anti-feeding of the nut by changing the material of the nut and increasing the method of tightening the nut, but these methods cannot fundamentally solve the problem, and increase the tightening nut while taking up more space.
We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: brass nuts, roller round head pins, non-knurled 304 stainless steel screws, GB93 anti-loose washers and other products, we can provide you with The right fastener solution for you.
