Efficient and secure fastening is crucial when installing protective layers on roofs and walls. A11 Staples – 20 Gauge, 3/8″ Leg x 3/8″ Crown (5,000 Count), available through A1A Wholesale Supply, provide the consistent performance needed for these tasks. These are a standard type of staple widely used in the construction industry, particularly compatible with tools designed for A11 or T50 series staples, including many popular hammer tackers and hand staplers from various manufacturers.
These staples are constructed from 20 gauge steel wire, offering a balance of strength and flexibility for penetrating various building materials. They feature a 3/8-inch leg length, which is a common size suitable for securing thinner materials without being excessively long. The 3/8-inch crown is the standard width for A11/T50 style staples, providing a good surface area for holding down materials like roofing felt or house wrap.
A common feature of these staples is a chisel point, designed for efficient penetration into wood sheathing and other building substrates. The steel is typically finished with electro-galvanization, providing a level of corrosion resistance suitable for many interior and exterior construction applications where extreme moisture exposure is not the primary concern.
These A11 staples in the 3/8″ x 3/8″ size are widely used by roofing contractors for fastening roofing felt (asphalt felt or synthetic underlayment) to the roof deck prior to shingle installation. They are also commonly used for installing house wrap on exterior walls, as well as for attaching vapor barriers, insulation facings, and other thin sheeting materials. Their ease of use with compatible tools makes them a fast and efficient fastening method for these applications.
The staples are conveniently packaged in boxes containing 5,000 staples (5M), a standard quantity that is practical for professional use on various job sizes. The staples are typically collated in sticks within the box for easy loading into stapler magazines.
