FAQ
Does a 3/8 washer have an exact 3/8 inside diameter?
No. The nominal size identifies the mating fastener. The actual opening includes clearance; check the listed dimensions before ordering.
Which side faces the joint?
Flat washers can generally be installed either way unless the product drawing or application specifies otherwise. Split lock washers should sit beneath the turning fastener component.
Can I use these outdoors?
304 stainless steel suits many general outdoor uses but is not a blanket recommendation for saltwater, pool chemicals, or highly corrosive exposure.
Are bolts or nuts included?
No, unless package contents explicitly state otherwise.
