The Bostitch STCR50191/4-6M staples are fine-gauge PowerCrown staples built for light- to medium-duty stapling jobs. With a 1/4" leg length and a 7/16" crown, they deliver a clean, reliable clinch — ideal for tasks such as document binding, mailers, light packaging, brochure assembly, paper bundles, light-cardboard work, insulation backing, sheathing paper, or house-wrap fastening.
These staples are constructed from galvanized heavy-gauge wire (approx. .050" × .019") for durability, corrosion resistance, and consistent performance even under repeated use. The PowerCrown design helps improve driving force and reduces misfires or staple buckling, giving a secure hold on lighter materials while keeping staple intrusion minimal. Supplied in a large 6,000-staple pack, they are a cost-effective solution for offices, mailrooms, packaging stations, print shops, or general-purpose stapling needs.
