Metallics JWW80G – Frequently Asked Questions
1) Are these galvanized washers OK for outdoor or damp locations?
These are galvanized steel with a galvanized finish, grey in color, so they hold up in damp interior spaces and general exterior use far better than plain steel. Note that galvanized is not stainless: for coastal exposure, chemical environments, or continuous wet service, specify stainless washers instead. Also avoid pairing galvanized washers with stainless or aluminum hardware where dissimilar metal corrosion is a concern.
2) How many washers come in the Metallics JWW80G jar?
One hundred 1/4 inch USS flat washers per jar, packaged in a screw-top jar rather than a bag or box, which is why it stays upright on a van shelf and pours without spilling. Shipping weight on the jar is 0.7 lbs.
3) Will a flat washer keep a bolted connection from loosening under vibration?
No. A USS flat washer like the JWW80G is for distributing load and stress across the bearing surface, not for locking. If the joint sees vibration, add a split lock washer, a serrated flange nut, or a nylon-insert lock nut in 1/4-20 along with the flat washer.
