Why Our Metal Cap Fasteners are the Professional’s Choice
- Ultimate Tear Resistance: The 1-inch galvanized steel cap provides a rigid surface that distributes pressure evenly, preventing material pull-through even in hurricane-force winds.
- High-Grip Ring Shank: Our 11 gauge nails feature deep annular rings that lock into the wood substrate, providing 2x more holding power than smooth shank nails.
- All-Weather Durability: Unlike plastic, the galvanized tin caps will not degrade under UV exposure or crack in freezing temperatures, ensuring 25+ years of performance.
- Watertight Protection: The wide cap design acts as a built-in washer, sealing the nail penetration point to prevent moisture infiltration into the roof deck.

Frequently Asked Questions (FAQ)
Q1: When should I choose Metal Cap Nails over Plastic Cap Nails?
