Roberts 3/8" Divergent Point Staples (5000 Pack) are heavy-duty staples designed for use with staple hammers, particularly the Roberts 10-109 Staple Hammer. These staples feature a 60° point angle that allows for easy penetration through materials like vinyl tile, linoleum, felt, and wood—including hardwoods. Their unique divergent point design causes the legs to veer in opposite directions upon impact, providing enhanced holding power and security.
