Serrated nut is a kind of lock nut with ridges on the surface of the nut, which can snap into the tightened surface. The splines are angled to prevent the nut from turning in the direction in which the nut loosens. Due to the grooves, they cannot be used with gaskets or on non-scratched surfaces….
Flange nut is a kind of nut with a wide flange at one end, which is used as a built-in washer. This is used to distribute the nut pressure on the fixed parts, reduce the possibility of damage to the parts, and make them less likely to loosen due to uneven clamping surfaces. These nuts…
DIN 934 nut is also called hexagonal nuts, with metric coarse and fine threads. Product grades are A and B. Class A is used for specifications less than or equal to M16, and Class B is used for specifications greater than M16. For grade 8, according to DIN standard, all hexagon nut sizes should use…

Classification of hex nuts：General purpose hex nuts, hex thick nuts, hex thin nuts, fine pitch hex nuts, hex flange nuts, nylon lock hex nuts, all metal…
Screw nut is a part of fasteners, it works together with screw bolts, thread rods, and the bolts or rods should be the same size and same threaded screw as the screw nuts. Threaded screw nut with different standards for different industry works. the main standards are DIN, ISO, JIS, ASTM/ANSI. Screw nut works for…
Grade 8 bolts refer to grade 8 high strength bolts, which are generally defined as grade 8.8 bolts. The first number represents 1 / 100 of the tensile strength, and the second number represents 10 times the ratio of yield to tensile strength. The tensile strength of Grade 8 bolts or grade 8.8 bolts is…
How to loosen the rusted screw and nut? Screws and nuts exposed to the air, a long time will rust, so for safety and aesthetic considerations, we need to remove these rusty fasteners and replace them with new ones. So this is a problem we need to help users solve as a supplier of fasteners….
Bolts break and its causes, This problem occurs in the process of bolt installation and the use of engineering and machinery, because the bolt fracture will stop our further production work. Therefore, it is necessary to analyze the causes of bolt fracture and how to avoid this situation. Reasons for bolts broken: Bolts break and…
