Flat Head UNC Screws – The Comprehensive Range for Every Application

Flat head UNC screws are the first choice for flush and visually appealing connections in the American standard. With a special 82° countersunk angle (as opposed to 90° for metric screws), they can be fully recessed into the material, ensuring a perfectly flat surface without protruding heads. This is not only a crucial advantage for aesthetics and aerodynamics but also minimizes the risk of injury and protects against snagging in dynamic applications.

Our range covers all common surface finishes and materials:

  • Stainless Steel (Inox): Offers maximum corrosion resistance, ideal for outdoor use, marine environments, and the food industry.

  • Zinc-Plated Steel: The zinc plating provides reliable protection against corrosion and gives the screw a shiny, decorative surface.

  • Plain Steel (unfinished): For industrial applications where the surface will be further processed after assembly (e.g., painting).

We offer these high-quality flat head screws with a variety of drives:

  • Hex Socket: For high torque transmission and a classic, secure fit.

  • Torx: The Torx profile enables optimal power transmission and minimizes the risk of cam-out, which is particularly beneficial for high-torque applications.

  • Phillips: The universal standard for quick and easy assembly, widely used in industry and crafts.

  • Slotted: The classic drive for traditional applications and restorations.

The versatile applications of these screws make them an indispensable range:

  • Vehicles & Motorcycles: Specifically for US cars, vintage cars, and American motorcycles that are manufactured to inch standards.

  • Industry & Mechanical Engineering: Suitable for US machinery and equipment where UNC threads are standard.

  • Agricultural Machinery & Road Construction: Robust connections for heavy-duty outdoor use.

  • Trax & Archery: For special fixings on off-road vehicles, trailers, and precision sports equipment.
