Stanley STHT71838 Heavy-duty Narrow Crown Staples 9/16in

Product Description

The STANLEY STHT71838 is a heavy-duty narrow crown staple designed for use with compatible pneumatic and manual staple guns in construction, insulation, sheathing, and general fastening applications. Each staple features a flat crown style with a 0.422-inch crown width and a 9/16-inch leg length, providing strong holding power in wood substrates and similar materials. Constructed from steel, these staples deliver consistent drive performance and resistance to deformation under load. The pack contains 1,250 staples, making it a practical supply quantity for ongoing job-site or shop use. Licensed contractors, framers, and general tradespeople rely on this staple style for repetitive fastening tasks where crown width and leg penetration must meet specific project requirements.

These staples are suited for residential and light commercial construction tasks, including subflooring, roof sheathing, housewrap attachment, insulation batts, and wood-to-wood fastening. The narrow crown profile limits surface damage and keeps fasteners low-profile in finish-sensitive applications. With a heavy duty rating, these staples are intended for use in powered staple guns rather than light-duty manual tools. They are a standard consumable on framing, roofing, and general carpentry job sites where high-volume fastening is routine.
