Summary of information:We have more than ten years of production experience in the screw industry, the main products are: stud bolts, nylon rub...

Compared with the prior art, the beneficial effects of Guangdong Yueluo Hardware Industry Co., Ltd. are as follows: the square nut has a simple structure, strong practicability and good fastening effect, which changes the smooth plane design of the traditional square nut. There are circular protrusions, and strip protrusions and strip grooves are respectively provided at the two circular protrusions to increase the roughness of the contact surface of the nut, thereby effectively increasing the friction between the nut body and the fastener. , to achieve a good tightening effect.

Specification label broadcast representation format: Thread specification d=M12, nominal length L=80mm, and performance level 4.8 equal-length stud bolts are completely marked as: GB 901 M12×80 [1] Product example: Stud studs are generally required After surface treatment, there are many types of bolt surface treatment, commonly used are electroplating, blackening, oxidation, phosphating, electroless zinc flake coating treatment, etc. However, electroplated fasteners account for a large proportion of the actual use of fasteners. Especially in automobiles, tractors, home appliances, instrumentation, aerospace, communications and other industries and fields are more widely used. However, for threaded fasteners, not only a certain anti-corrosion capability is required in use, but also the interchangeability of threads must be ensured, which can also be called screwability here. In order to meet the dual-use performance of anti-corrosion and interchangeability required by threaded fasteners in use, it is very necessary to formulate special plating standards.

T-bolts are often used in conjunction with flange nuts, which are standard supporting connectors when installing corner fittings, and can be automatically positioned and locked during the installation process. At present, in the welding process of T-bolts, there is often a method of manual welding. Using such a method, the manufacturing cycle is long, the labor intensity is high, the production efficiency is low, and the welding quality is difficult to guarantee.

At present, there is an anti-theft T-bolt in the prior art, which is composed of a screw rod and a bolt head connected with the screw rod; the screw rod is composed of a polished rod and a threaded rod; a concave hole is provided at the bottom end of the screw rod; cylindrical, and the diameter of the cylindrical bolt head is larger than the diameter of the screw. When the above-mentioned anti-theft T-bolts are in use, the user usually hammers the concave hole at the bottom end of the screw with a hammer or other tool to deform it, destroy the thread structure on the screw, and fix the nut with a deformed object, so as to achieve anti-theft. Features

The main technical problem to be solved by Guangdong Yueluo Hardware Industry Co., Ltd. is to provide a rivet that can choose the breaking point, which can not only solve the bad effect caused by random shearing, but also can keep the mandrel in the hole to increase the strength after riveting, and also When the same type of rivet is riveted with different riveting thickness, changing the mandrel breakpoint can always make the mandrel breakpoint break at the required place, improve the tensile and shear strength of the rivet, increase the riveting quality of the product, and prolong the service life of the rivet.

We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: color plated square slant washers, GB6178 hexagon slotted nuts, round aluminum washers, U-shaped positioning pins and other products, we can help you Provide the right fastener solution for you.
