How to choose
- USS vs. SAE: USS flat washers have a larger outside diameter and are thicker, for wood and soft surfaces; SAE washers are smaller and fit tighter around the bolt for machinery
- Fender washers: a much larger outside diameter (for example 1-1/4 in. on a 1/4 in. bolt) spreads the load on sheet metal, plastic and thin panels
- Split lock washers: go under the nut or bolt head to resist loosening from vibration
- Match the finish: use zinc washers with zinc bolts and stainless with stainless to avoid galvanic corrosion
