The Fasco ESBNK4023-14 staples are fine-wire staples built for light- to medium-duty stapling tasks — ideal for applications such as upholstery, furniture backing, sheathing, insulation securing, light wood paneling, and other jobs needing a strong but subtle hold. Their 9/16" leg length and 1/2" crown provide enough penetration for medium-thickness materials while maintaining a low profile and minimizing surface damage.
Constructed from 21-gauge galvanized wire, these staples offer good corrosion resistance, smooth driving, and reliable clinch without over-penetration — making them well-suited for indoor, construction-adjacent, or finishing tasks. Supplied in a 10,000-staple pack, they offer excellent value and are ideal for repeated staple use in workshops, upholstery shops, or packaging environments.
