a) A self-tapping screw for thermoplastics is a specialized fastener designed to create its own threads as it is driven into plastic materials.

b) These screws have wider, sharp, and deep threads, which allow them to cut into the softer thermoplastic material efficiently, creating a secure, long-lasting hold.

a) This bolt features an external hexalobular socket with a small flange, and is designed for applications requiring a high torque transfer with reduced risk of cam-out. 

b) The star-shaped head allows for great torque transfer by distributing the load more evenly across the drive, compared to traditional drive systems like Phillips, Pozi or slotted.

a) A ribbed neck screw is a type of fastener designed with a special feature on its shank or neck. Instead of a smooth or threaded surface, the neck of the screw has ribbed, serrated, or knurled features. These ribs or serrations provide additional grip and resistance when the screw is driven into a material, preventing it from rotating or loosening.
