FAQ

Internal or external tooth lock washer?
External teeth grip more surface and hold better. Internal teeth hide under the screw head for a neater look.

Do I need a washer?
A flat washer spreads the load, protects the surface and stops the nut or head from digging in. Use a stainless washer with stainless fasteners.

Will 410 stainless tooth washers rust?
410 stainless is hardened for spring and bite, but it is less corrosion resistant than 18-8. It can show light surface rust in wet or salty locations.
