1/4 in. x 5/8 in. O.D. Galvanized Bonded Sealing Washers

Master Seal Washers are perfect for attaching sheet metal or even fiberglass panels for exterior applications

FEATURES:

• EPDM gasket bonded to washer for water-tight seal
• Ideal for most applications where the primary concerns are ultraviolet light degradation, temperature extremes, and ozone attack.
• Installation is simple. Just thread the washer onto a galvanized Pan Head, or Round Washer Head screw

INSTALLATION INSTRUCTION:

• Fasten with sufficient force to flatten the washer
• Do not over-tighten the screw so that the metal part of the washer embeds into the rubber.

Check local building requirements for the code on fasteners before building.

Warning: Do not mix metals like Galvanized and Stainless Steel. The mixing of dissimilar metals will cause Galvanic Corrosion. Please see our information in McFeely's University on Corrosion in Fasteners.
