Upgrade your fastening solutions with Hard-to-Find Fastener Combination Truss Head Machine Screws. Crafted from high-quality zinc-plated steel, these screws offer exceptional strength and corrosion resistance for reliable performance. The combination drive design allows flexibility with Phillips or slotted tools, while the wide truss head provides a secure grip without damaging surfaces. Perfect for metal, wood, and plastic applications, these screws are ideal for DIY projects, home repairs, and industrial use. Not all fasteners are applicable for all applications so be certain to test thoroughly and get the opinion of a licensed building or certified building or structural engineer before relying on these fasteners for any situations where failure would result in damage to property or person.

  • Truss Head Machine Screws: The wider diameter heads make them ideal for load-bearing joints and low-profile connections. Provides a large bearing surface for secure fastening without damaging materials.
  • Combination Head Screw: The versatile heads are compatible with multiple screwdriver bits for convenience. Features both Phillips and slotted drive options for easy installation with standard tools.
  • Thread Design: The threading provides higher shear resistance for secure fastening in joints. Designed for smooth engagement and strong hold in pre-tapped holes or with nuts.
  • Durable Zinc Plated Steel: Corrosion-resistant finish ensures long-lasting performance and a clean, bright appearance—perfect for indoor and light outdoor environments
  • Versatile Use: Suitable for cleaner, smoother joins in simple construction including framing, sheathing, and decking. Available in various lengths and diameters to suit different project needs.
