What is the national standard for hexagonal thin nuts?
The national standard for hexagonal thin nuts refers to the standard hexagonal thin nuts specified in Chinese national standards such as GB/T127. Compared with ordinary nuts, its characteristics are that the external dimensions of the nut are thinner and the weight is lighter.
What are the materials for hexagonal thin nuts according to the national standard?
The national standard for hexagonal thin nuts is generally made of materials such as ordinary steel (35 #, 45 # nuts), carbon steel, stainless steel (304, 316), tin, zinc, nickel, etc., to meet the various requirements of users under different working conditions.
What are the external dimensions of hexagonal thin nuts according to the national standard?
According to the GB/T127 standard, hexagonal thin nuts are divided into M-type, W-type, and G-type. The outer diameter of M-type is generally 3mm-20mm, W-type is generally 10mm-20mm, and G-type is generally 14mm-20mm.
What are the characteristics of using hexagonal thin nuts according to the national standard?
(1) When tightening the loose screw, the locking force is strong, and the tightening is concentrated, with good adhesion;
(2) Has high resistance to tightening and twisting, able to withstand heavy loads;
(3) After tightening, it is not easy to loosen, and the lock groove design is more secure when disassembling;
(4) Lightweight, efficient disassembly and installation, high tensile strength, small area, and small installation space.
What are the installation methods for hexagonal thin nuts according to the national standard?
(1) Nut fixed installation: fix the nut on the machine or equipment and connect it with bolts;
(2) Convex end nut installation: Connect the bolt and product thread together through a convex end nut;
(3) Side nut installation: Connect the end face of the nut to the pitch bolt through a screw to support the bolt installed on the pitch;
(4) Bearing installation: The nut shaft end will be fixed to the machine to maintain the positioning of the shaft.
