SupplyApp has heavy-duty staples and brad nails to ensure you don't run out when it's time to refill your staple or nail gun. Galvanized steel construction provides strength and longevity to power crown and flat crown staples. Select a leg length that is appropriate for your staple gun and the jobs you perform. With legs that veer in different directions, divergent point staples can provide increased holding power. Fill your nail gun with the appropriate size of 18-gauge steel brads.
