The 304 Stainless Steel Internal Tooth Lock Washer and an External Tooth Lock Washer are both types of lock washers designed to prevent bolted joints from loosening due to vibration or expansion/contraction. Both internal and external tooth lock washers are essential for maintaining the integrity of fastened joints, ensuring they remain secure even in high-vibration conditions or extreme environmental settings. Both types of tooth lock washers leverage their serrated teeth to mechanically lock a fastener in place, with the choice between internal and external depending on the specific fastener size, aesthetic requirements, and the desired level of locking force. The 304 stainless steel material ensures good corrosion resistance for the application.
