Bostitch stcr50199/16-4m Heavy Duty Staples 9/16 in 4000PK

Product Description

The BOSTITCH stcr50199/16-4m is a heavy-duty steel staple designed for securing thick or tough materials that standard staples cannot handle. With a 9/16-inch leg length, a 7/16-inch Power Crown width, and a wire gauge of 0.050 x 0.019 inches, this staple delivers the holding strength required in construction, upholstery, and industrial fastening applications. The Power Crown style distributes clamping force across a wider footprint, reducing material tear-out and improving retention in demanding substrates. Each pack contains 4,000 staples, making it a practical supply for high-volume jobs or stocking a service vehicle.

These staples are suited for use in heavy-duty pneumatic and electric staplers where deeper penetration and higher pull-out resistance are required. Typical applications include wood framing, subfloor attachment, sheathing, upholstery work, and industrial assembly operations. They are specifically designed for use with the PC4000-OC2 stapler. The steel construction and silver finish hold up to job-site conditions, including repeated loading cycles and moderate environmental exposure.
