Selection and installation notes
- The teeth leave marks on the surface; keep this in mind before using it on painted, coated or visible surfaces.
- The teeth become dull after removal; fit a new washer instead of reusing it.
- Choose the bolt, nut and washer in the same grade; mixing grades upsets the corrosion balance of the joint.
- AISI 304 is intended for general use; choose AISI 316 for chloride media, sea water and swimming pool applications.
- Direct contact between stainless steel and galvanized or carbon steel can cause galvanic corrosion; use insulation (washers, unions) between different metals.
