SAE J 891(Figure7)-2016 ShapeWide-range Design Spring NutsWith OrWithout Retaining Extrusion

Reed Nuts U-type Insert Nuts, Cleat Nuts , Shrapnel Nuts M12 M10 M8 M6 M5 M4 M3,Use these light-duty clip-on nuts in low-clearance applications. Also known as U-style clip-on nuts, they firmly clip onto the edge of panels and stay secure. Zinc-plated steel clip-on nuts are corrosion-resistant in wet environments. Black-phosphate steel clip-on nuts are mildly corrosion-resistant in dry environments.    

Self-Tapping Screws + Reed Nuts or Plate Spring Nuts
Self-tapping screws are in metal or non-metallic materials in the pre-drilled holes tapped out of their own with the internal threads of a fastener, self-tapping screws are generally metal materials, prefabricated mounting holes in the threads are extruded by the rotating self-tapping screws or cut out. Self-tapping screws in accordance with the screw head shape are divided into: pan head, countersunk head, large round head, flange head, and hex head, etc., in accordance with the screw tooth angle divided into ST threads and TP threads. ST tooth angle of 60 °, TP tooth angle of 30 °, in general, 30 ° of the tooth angle, radial stress can be reduced, to improve the fluidity of the material, and at the same time, the pitch of TP threads is greater than the ST threads, which can allow for a deeper thread engagement in the plastic and the load between the screws. The load ratio between the plastic and the screw is more equal. Therefore, it is currently recommended that TP thread tapping screws be preferred for self-tapping screws screwed into plastic parts.Self-tapping screws matched with multi-threaded reed nuts or single-threaded leaf spring nuts are mainly used in the connection between the instrument panel and the crossbeam, and this type of connection is the connection between the metal self-tapping nail and the metal nut, and its main advantages are that there is no need to pre-process the internal threads of the connected parts, it is easy to realize the rapid automation of the assembly, and it has a high tightening torque, and it has high connecting strength, good firmness, and low cost.
