The JK694-9 heavy-wire staples are industrial-grade fasteners designed for heavy-duty stapling tasks — especially useful for carton closing, crate and pallet assembly, packaging, and other demanding fastening needs. With a 3/8" leg length and a 7/16" crown, these staples deliver strong penetration and a secure clinch for corrugated cardboard, multi-layer containers, crates, and thick materials.
Made from heavy-wire steel, the staples offer durability and resistance to bending or misfires, even under repeated, heavy use in warehouse, packaging, or manufacturing environments. Their robust construction makes them compatible with plier-style or pneumatic staplers that accept JK694-series heavy staples. The 5,000-staple pack provides ample supply for frequent or bulk stapling operations.
