The Freeman 21° .120" x 3" Plastic Collated Stainless Steel Ring Shank Full Round Head Framing Nails are engineered for strength and long-term durability in harsh environments. Made from 304 stainless steel, these nails resist rust, corrosion, and staining, making them ideal for natural wood and pressure-treated lumber. Built for framing, subfloors, roof decking, pallet and shipping crate assembly, decks, and docks, the ring shank design ensures superior withdrawal resistance, keeping structures secure even under heavy use. Each contractor-size box includes 2,500 stainless steel framing nails, minimizing reloads and boosting efficiency on large projects. The 21° plastic collated strips ensure consistent feeding and jam-free firing in most 21° framing nailers, including Freeman's PE20V2183, G2FR2190, G22183CLW, PFR2190, and other industry-standard models.
