Auveco 1061 #6 Shakeproof External Tooth Lock Washer 100-Pack

The Auveco 1061 is a #6 Shakeproof External Tooth Lock Washer, sold in a convenient 100-piece pack. Designed to prevent loosening caused by vibration and dynamic loads, these external star lock washers feature serrated teeth around the outer diameter that bite into both the mating surface and the fastener bearing face, creating a secure mechanical lock.

External tooth lock washers — also known as shakeproof washers or star washers — are widely used in automotive, electrical, and general industrial assembly applications where reliable fastener retention is critical. Their external tooth design provides maximum locking performance and is especially effective on soft materials.
