Secure your hardware, sheet metal, and plastic components with a sleek, low-profile finish using our Black Pozi Countersunk Self-Tapping Screws. Supplied in a convenient pack of 100, these fasteners combine the rapid thread-cutting efficiency of a Type AB point with the superior torque transfer of a Pozi drive. Finished in a specialized black coating for enhanced corrosion resistance, they are the perfect choice for automotive interiors, stage set construction, audio equipment, and any project where an unobtrusive, dark aesthetic is essential.

Feature Icon
Sleek Flush Finish: The countersunk head sits completely level with the surface of your material, providing a smooth, professional, and snag-free result.
Feature Icon
Corrosion Resistant Black Coating: The durable black finish not only looks great but acts as a protective barrier against rust and oxidation in damp environments.
Feature Icon
Precision Pozi Drive: The cross-recessed Pozi drive ensures deep bit engagement, drastically reducing the risk of slipping (cam-out) and protecting the black finish from scratches.

Unobtrusive, Professional Aesthetics

Standard bright zinc or silver screws can easily ruin the look of a dark workpiece, drawing the eye away from the craftsmanship. Whether you are building custom audio enclosures, restoring a classic car interior, or fitting black architectural hardware, these screws are designed to disappear. The dark finish blends perfectly into black or dark-stained materials, while the countersunk head drops entirely flush with the surface, leaving a smooth, uninterrupted finish that looks highly professional.

Superior Pozi Drive Power

Driving screws into metal or dense plastic requires a lot of rotational force. Standard Phillips or slotted screws can often "cam out" (slip out of the recess) under high torque, which not only damages the screw head but can cause your drill to skid across your workpiece, scratching the black finish. The Pozi drive design solves this by featuring four additional structural lines radiating from the center. This gives your screwdriver bit a much tighter, more positive grip, allowing you to apply heavier pressure safely and efficiently.

Precision Tapping with AB Points

When you are working with enclosed box sections or attaching components to a panel where you can't reach behind it, you need a fastener you can trust. The Type AB point is engineered specifically for these "blind" fastenings. Once you have drilled a pilot hole, the sharp tip catches the material instantly. As it drives, the hardened steel threads act like a mechanical tap, carving a tight, custom-fit thread directly into the sheet metal or plastic substrate. This creates a secure, vibration-resistant hold using only front-facing access.

Key Features

  • Type AB Point: Features a sharp locating point and closely spaced, fine threads for excellent grip in thin sheet metal, plastics, and wood.
  • Single-Sided Assembly: Taps its own highly secure mating thread into pre-drilled holes, eliminating the need for a backing nut in blind assemblies.
  • Aesthetic Integration: Designed to blend seamlessly with dark timber, black powder-coated hinges, brackets, and automotive trims.
  • Hardened Steel Core: Built to withstand high driving torque without shearing or stripping the threads.
  • Trade Pack: Supplied in a cost-effective box of 100 pieces, ideal for high-volume manufacturing or stocking the workshop.

Frequently Asked Questions

Will I need a special screwdriver bit for these?

Yes, you should use a Pozi (PZ) driver bit, not a standard Phillips (PH) bit. Using a Phillips bit in a Pozi screw will result in a loose fit and can strip the black coating off the head of the screw.

Do I need to drill a pilot hole first?

Yes. The AB point is sharp enough to catch the material easily, but it is not a drill bit. You must pre-drill a pilot hole, and ideally use a countersink bit to create a recess so the head can sit perfectly flush.

Is the black finish durable enough for outdoor use?

The black finish provides a good level of corrosion resistance, making it suitable for damp indoor areas, automotive interiors, or sheltered outdoor use. However, for fully exposed, harsh outdoor weather, stainless steel fasteners are always the best choice.
