Tough 410 Stainless Steel Concrete Fasteners

Designed for demanding masonry and exterior fastening applications, these 1/4 in. x 1-1/4 in. concrete fasteners feature durable 410 stainless steel construction and a self-threading design. They are ideal for securing materials to concrete and masonry without relying on traditional anchors.

These fasteners are well suited for exposed exterior projects such as mounting signs, securing park benches, installing handrails, fastening bottom plates, and other concrete or masonry applications where dependable holding power is important. Unlike softer stainless steel grades, 410 stainless steel can be hardened, making it particularly well suited for concrete fasteners that need strength and durability.

410 stainless steel provides corrosion resistance for exterior use, although it is not as corrosion resistant as more common stainless steel grades. After prolonged outdoor exposure, a light red tint may develop on the surface. This characteristic does not detract from the fastener's suitability for many exterior masonry applications.

Benefits and Features

  • 410 stainless steel construction: Hardenable stainless steel provides the strength needed for concrete and masonry fastening.
  • Self-threading design: Fastener threads into the pilot hole to provide a secure connection without a conventional masonry anchor.
  • Exterior applications: Suitable for exposed outdoor projects including signs, benches, handrails, and bottom plates.
  • Hex head: The 5/16 in. hex head provides a practical drive surface for installation.
  • Concrete and masonry fastening: Designed specifically for securing materials to concrete and similar masonry surfaces.
  • Required pilot hole: Uses a non-standard 3/16 in. diameter pilot hole for proper installation.
  • Bulk quantity: Includes 100 fasteners for larger projects, repairs, and shop or jobsite inventory.
