FAQ
Flanged or plain cup washer?
The flanged style has a wider rim that spreads the load further and covers the edge of the hole.
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.
Should I use 18-8 or 316 stainless?
18-8 is fine for most outdoor and wet jobs. 316 stainless adds molybdenum for better resistance to salt water, chlorides and many chemicals, so it is the better choice for boats, docks, pools and coastal sites. Contact us for 316 stainless.
