Wood Screws

Wood Screws are specially designed fasteners with a coarse thread and sharp point, intended for joining wood to wood or attaching wood to other soft materials. Unlike machine screws, wood screws feature a partially threaded shank, which allows for a tight grip and strong hold as the unthreaded portion pulls materials together during installation.

These screws are commonly used in carpentry, cabinetry, furniture making, and general construction. Their coarser thread pitch provides better bite and holding power in wooden substrates, reducing the chances of splitting or loosening over time.

Wood screws are available in a variety of head styles and drive types, including:

  • Slotted Head

  • Phillips Head

  • Star Drive (Torx) Head

Adfast Component manufactures wood screws in a wide range of durable and corrosion-resistant materials, such as:

  • Stainless Steel 18-8, 304, and 316

  • Zinc-Plated Steel with Black Oxide Finish

  • Cadmium or Nickel-Plated Finishes

These options make our wood screws ideal for both indoor and outdoor applications, offering strength, longevity, and ease of installation across a variety of woodworking projects.
