Bulk Pack Of Thirty Thousand Number Four Tooth Lock Washers With Sharp Internal External Teeth For Heavy Duty No Slack Retention And Rock Solid Electric Grounding On Aluminum Or Plastic

#4 Inch Tooth Lock Washers Bulk Pack Of Thirty Thousand
✔️ Zn coated spring steel, firm torque lock and steady grounding surface

This mass lot ships thirty thousand number four tooth lock washers built to clamp down fasteners without backing off when engines or motors shake hard. Workers drop them onto aluminum brackets, plastic housings, and steel frames where standard ring washers just slide around. The sharp twisted teeth dig right into softer mounting materials to eliminate back and forth play.

✅ Internal and external serrated teeth bite into soft materials to stop turning
✅ Clear zinc plating keeps steel corrosion free during outdoor or damp storage
✅ Rockwell hardness rating sits between C40 to C50 for lasting structural strength
✅ Inch profile aligns perfectly with standard #4 hardware for fast project builds

💡 Why do industrial fabricators find serrated lock washers handy for fighting fastener fatigue on moving equipment? Tooth lock washers solve slipping problems by driving their jagged teeth straight into the base material to kill rotation. Crews on the job site call this setup a no nonsense way to maintain clamp force without carrying extra locking nuts. - Jagged ring cuts into sheet metal to lock bolt position under continuous rumble - Continuous conductive edge links separate wires for reliable static discharge routing - Spring tempered core flexes slightly to absorb impact loads without losing grip strength
