Standard 12J staples with 13.1mm / 1/2 inch crown are generally suitable for many manual, electric and pneumatic staple guns. Always confirm the tool accepts 20 gauge 12J staples and the required leg length.
Available materials include galvanized wire, stainless steel and aluminum. Galvanized wire is common for indoor use, while stainless steel is better for higher corrosion resistance requirements.
A chisel point staple has an angled sharp point that helps the staple penetrate material more accurately and easily. It is useful for wood, vinyl tile, linoleum, felt, foam and upholstery materials.
Each box contains 5,000 staples, and each stick contains 100 staples. Carton quantity depends on staple length, with common packing options of 20, 30 or 40 boxes per carton.
Electrogalvanized staples offer some corrosion resistance, but they are mainly recommended for indoor or protected use. For outdoor or humid applications, stainless steel staples are usually a better choice.
Choose length according to material thickness and required holding power. Shorter 6mm or 8mm staples are better for thin fabric and light materials, while longer 16mm, 19mm or 22mm staples are better for foam, felt, wood and layered materials.
