Maze Nails H526A050 Pole Barn Nail 20d 4 in 7 Gauge 50 Lb

Product Description

The MAZE NAILS H526A050 is a 20d, 4-inch, 7-gauge oil-quenched hardened ring shank nail designed for pole barn construction and heavy structural fastening. The oil-quench hardening process increases shank hardness, improving drive performance through dense or treated lumber. The ring shank profile provides superior withdrawal resistance compared to smooth-shank nails, making it well suited for applications where fastener pull-out is a critical concern. This bulk carton contains approximately 1750 nails and weighs 50 pounds. Installation is performed by framing carpenters and construction crews working on agricultural, commercial, and residential pole buildings.

These nails are intended for pole barn framing, post-frame construction, and heavy timber fastening where structural integrity and long-term holding power are required. The 20d penny size and 7-gauge wire diameter make them appropriate for through-nailing dimensional lumber, girts, and purlins to structural posts. The oil-quenched hardening helps the nail withstand the driving forces required when fastening into pressure-treated or hardwood framing members commonly found in agricultural and light commercial structures.

Key Features

• Oil-quenched hardened shank for increased hardness and drive performance through dense or treated lumber
• Ring shank profile for high withdrawal resistance in structural connections
• Complies with ASTM F1667 standard specification for driven fasteners
• 20d penny size, 4 inches in length, 7-gauge wire diameter
• Bulk carton of approximately 1750 nails at 50 pounds for high-volume jobsite use

Compatibility

Designed for use in pole barn framing, post-frame construction, and heavy structural lumber fastening applications requiring an ASTM F1667-compliant ring shank nail in 20d sizing.

Installation Notes

Installation is typically performed by framing crews following applicable building code requirements for structural fastening. Safety glasses are recommended when driving hardened nails, as the increased shank hardness raises the risk of nail or chip ejection on contact with knots or dense grain. Confirm fastener specifications meet local building code and engineered plan requirements before installation. Do not use damaged or bent nails, as hardened shanks are more brittle than standard wire nails.
