Price is for one pack of 10 washers. Save yourself over 10% on buying them individually.

What is Chamfered? Washers used for high torque applications have an internal chamfer which prevents the very small radius under the bolt head from 'galling' as it allows the bolt to sit fully and correctly in the washer.
