Hex Thin Nut

四角焊接螺帽 

a) This metallic nut features a flanged base with serrated grooves encircling its body.

b) This part is used for secure fastening in mechanical assemblies, with features designed to resist loosening under vibration.

c) The external structure, the serrated grooves or knurls, enhances grip for improved stability. 

Steel two pieces hex collar cap nut

a). Prevailing torque type hexagon nuts feature a design where increased friction within the threads prevents the nut from loosening on its own. This friction is generated by the prevailing torque element integrated into the nut, which induces axial and/or radial clamping in the bolted connection.

b). DIN 980 (Type V) prevailing torque type hexagon nuts. Single-piece metal nut without an insert, in which increased friction is generated through the deliberate deformation of the prevailing toruqe element of the nut.

Carbon steel hex collar weld nut heat treated

a) A square weld nut with prongs or projections is a type of fastener designed for welding to a metal surface. It is a square-shaped nut with four prongs on one side, which assist in the welding process and provide additional stability during installation.

b) Nycote prevents adhesion of weld spatter. This protective coating also improves lubricity and reduces installation drive friction.
