0173339 1/2 In Bonded Washer 18-8 Stainless Steel / Neoprene

1/2″ bonded washer. 18-8 stainless steel construction with a neoprene bonding helps seal the joint and prevent leakage. Disperses the surface pressure of the screw to prevent friction and reduce the risk of the bearing surface sinking, leading to looseness.
