Grip-Rite Cap Nails GCB134 1-3/4 Inch 12 Gauge (Ring Shank Electrogalvanized Steel 1 Inch Round Plastic Head 2000-Count Roofing Fastener Set)

Grip-Rite GCB134 1-3/4" x 12-Gauge Ring Shank Plastic Cap Roofing Nails 2000-Pack

The Grip-Rite GCB134 2,000-count box of 1-3/4-inch 12-gauge plastic round cap roofing nails fastens roofing felt underlayment, weather-resistant house wrap, and foam board sheathing securely to wood decking. Engineered with high-holding annular ring shanks and a rust-resistant electrogalvanized zinc coating, these durable steel fasteners prevent blow-offs, pull-throughs, and tear-outs across plywood and OSB roof decks. Outfitted with 1-inch diameter high-visibility round plastic caps that seal moisture out and distribute holding pressure broadly, this bulk fastener pack equips roofing crews, siding installers, and residential carpenters with reliable, weather-tight installation performance.

Best Used For:

• Roofing Felt and Synthetic Underlayment Attachment: Securing asphalt-saturated felt, fiberglass paper, and synthetic roofing membranes to roof decking without tearing the sheet.
• Building House Wrap and Vapor Barrier Installation: Fastening weather-resistive building wraps and poly vapor barriers firmly across exterior wall sheathing.
• Rigid Foam Board and Sheathing Fastening: Affixing exterior foam insulation panels and soundproofing boards firmly against underlying wooden wall studs.

Key Performance & Safety Features

• 1-Inch Wide Round Plastic Caps: Large flexible round caps distribute clamping pressure over a wide surface area to eliminate fastener pull-through in windy conditions.
• Annular Ring Shank Geometry: Concentric rings lock directly into wood grain fibers to provide superior withdrawal resistance compared to smooth shanks.
• Electrogalvanized Zinc Coating: Protective zinc plating shields steel wire against rust, oxidation, and surface staining in humid exterior environments.
• 12-Gauge High-Tensile Steel Wire: Heavy-duty shank wire resists bending upon hammer impact when driving into dense plywood and framing lumber.
• High-Volume 2,000-Count Packaging: Bulk contractor pack provides ample fasteners for complete residential roofing and siding projects without frequent supply runs.

Technical Specifications

Pro-Tip: When installing synthetic roofing underlayment or house wrap, space plastic cap nails approximately 12 to 18 inches apart along seams; drive them flush without over-striking so the plastic washer creates a watertight seal without cracking the rim.
