KYA 20 Gauge 4J Series 5.2mm Crown Fine Wire Staples are precision fasteners designed for upholstery, furniture trim, screening, crafts, insulation, roofing felt, house wrap, picture frames, bedding, automotive vinyl, and light fastening applications. These 4J series staples use a 5.2mm crown, 20 gauge wire, chisel point, and glue collation for stable feeding and clean penetration.
Made from galvanized wire, stainless steel, or aluminum, these fine wire staples are available in lengths from 4mm to 25mm. The zinc plated finish helps improve rust resistance for interior and selected light-duty applications, while the fine wire design helps reduce visible marks on upholstery, fabric, trim, and decorative materials.
The following specifications help upholstery manufacturers, furniture factories, insulation suppliers, construction material distributors, tool dealers, and fastener importers confirm staple size, material, finish, tool compatibility, and packing details before ordering.

When selecting 4J series fine wire staples, buyers should confirm stapler compatibility, gauge, crown width, leg length, wire material, surface finish, point type, packing quantity, and application material. Shorter lengths such as 4mm, 6mm, and 8mm are suitable for thinner materials, while longer lengths such as 16mm, 19mm, 22mm, and 25mm provide deeper penetration for thicker substrates.
For upholstery and trim applications, galvanized fine wire staples are commonly used for clean fastening and basic corrosion resistance. For more demanding environments or special material requirements, stainless steel or aluminum options can be selected according to buyer specifications.
