Self threading metal screws are a type of screws with the ability to cut grooves by themselves. Their structural feature is that they integrate the thread forming function and the tightening function into a single component. This product revolutionizes the traditional tightening process through the synergy of geometric deformation and material mechanics.
Its cutting edge is precisely ground with hardened steel, and the tapered lead-in section guides the screw to accurately position. The progressive thread profile continuously squeezes the parent material during the screwing process, and the cold work hardening effect strengthens the newly formed thread groove. However, ordinary screws rely on pre-processed thread matching, and the assembly process is prone to slippage or positioning deviation.
The dual-lead thread layout of self threading metal screws is conducive to reducing the attack torque, and the spiral chip groove design avoids chip clogging. The full arc treatment of the tooth top reduces the stress concentration of the parent material, and the special angle of the tooth side balances the cutting efficiency and connection strength. Traditional self-cutting screws lack chip management capabilities and are prone to jamming in blind hole scenarios.
