Superior 34° cold-dip galvanized spiral (auger) paper strip nails designed for exterior applications demanding maximum withdrawal resistance and corrosion protection. JLHY's 33-year manufacturing capability includes in-house cold-dip galvanizing lines that apply a thick, uniform zinc coating meeting ASTM A153 standards — far superior to standard electroplating. The spiral shank design bites into wood fibers and locks permanently, eliminating the common problem of nail pops and back-out in exterior decking and fencing. Our automated spiral-threading machines ensure consistent thread pitch and depth on every nail for predictable holding power.

These CDG (cold-dip galvanized) collated nails are the contractor's choice for pressure-treated deck boards, CCA-treated lumber, and exterior fencing where hot-dip galvanized may be overkill but electro galvanized lacks durability. JLHY exports these nails globally to distributors in North America, Europe, and Australasia with full container loads, FOB pricing, and quality documentation including mill test certificates.
