Maze Hardened RS Polebarn Nails, 20D (4")

Maze Hardened RS Polebarn Nails, 20D (4")

The H-526-A Maze Hardened RS Polebarn Nails (20D, 4") are oil-quenched, hardened ring shank nails made for serious holding power in post-frame construction. Built to comply with ASTM F1667 Type 1, Style 30 for post-frame ring shank nails, they feature sharp ring shanks that bite hard into posts, trusses, and timbers. These are the “stay put” nails—just remember: hardened nails require safety glasses when driving, because flying metal is a terrible surprise.
