Key Features

  • Self-Tapping Design: Engineered to create its own mating threads upon installation, streamlining assembly and reducing the need for pre-drilled holes in thin materials.
  • Integrated Washer Head: The 5/8" washer diameter beneath the 5/16" hex head increases the bearing surface, enhancing load distribution and preventing pull-through on softer or thinner materials.
  • Durable Construction: Manufactured from hardened steel, these screws offer superior strength and resistance to stripping, ensuring a secure and lasting connection.
  • Corrosion Resistance: Typically zinc-plated, providing a protective barrier against rust and corrosion, crucial for longevity in exposed or harsh conditions.
  • Dual Drive Capability: The hex washer head often incorporates a slotted drive, allowing for versatile installation with either a hex driver/wrench or a flathead screwdriver.
