Secure sheet metal, plastics, and timber with a classic, flush finish using our Slotted Countersunk Self-Tapping Screws. Supplied in a trade-ready pack of 100, these fasteners feature a traditional single-slot drive and a sharp Type AB point that easily cuts its own precise thread. Finished in Bright Zinc Plating (BZP) for reliable indoor corrosion resistance, they are the definitive choice for architectural ironmongery, vintage restoration projects, and general fabrication where a clean, unobtrusive look is essential.

Completely Flush Finish: The countersunk head is designed to sit perfectly level with your material surface, preventing snags and ensuring a professional appearance.

Traditional Slotted Drive: Features a classic flathead recess, making it universally accessible and ideal for period-correct restoration work.

Rapid Thread Cutting: The sharp Type AB point is specifically engineered to catch instantly and tap its own secure thread into pre-drilled holes.

A Flush, Professional Finish

When installing hinges, brackets, or decorative faceplates, a protruding screw head can ruin the aesthetic and interfere with moving parts. The countersunk design of these self-tapping screws solves this issue entirely. When driven into a pre-countersunk hole, the angled underside of the head allows the screw to sink perfectly flush with the surface of your workpiece. This leaves a smooth, safe, and highly professional finish that won't catch on clothing or obstruct adjoining hardware.

The Classic Utility of the Slotted Drive

While modern drive types are common in heavy construction, the traditional slotted (flathead) screw remains an absolute necessity for specific trades. It is universally accessible—requiring only a standard flat-blade screwdriver—making it highly convenient for quick maintenance. More importantly, the slotted drive is the industry standard for restoration work. If you are refurbishing antique furniture, classic cars, or fitting traditional architectural ironmongery, a slotted screw maintains the period-correct, authentic visual appeal that modern cross-head screws disrupt.

Efficient Blind Fastening

Dealing with enclosed box sections or blind holes where you cannot reach behind to attach a nut can be frustrating. These self-tapping screws are engineered exactly for this scenario. After drilling a suitably sized pilot hole, the sharp Type AB point catches the edge of the material immediately. As you turn the screwdriver, the hardened, closely spaced threads carve a perfectly matched mating path directly into the sheet metal or plastic. This provides exceptional pull-out resistance and grip using only front-facing access.

Key Features

Type AB Point: Combines a sharp locating point with fine threads, making it highly effective for joining thin sheet metal, resin, and plastics.
Single-Sided Assembly: Creates a secure, vibration-resistant friction fit without the need to access the back of the material to attach a nut.
Bright Zinc Plated (BZP): The clear zinc coating protects the hardened steel core from oxidation and rust in dry or sheltered environments.
Classic Aesthetic: The traditional slotted head provides a vintage, authentic look often required for antique furniture repair or classic car maintenance.
Convenient Trade Pack: Supplied in a box of 100 pieces, providing excellent value for busy workshops and frequent fabricators.

Frequently Asked Questions

What is the difference between a Type A and a Type AB point?

Both have a sharp point, but a Type A screw has wider, coarser threads, whereas a Type AB screw has finer, more closely spaced threads. Type AB is generally preferred for thin sheet metals and brittle plastics where a finer thread provides better grip without tearing the material.

Do I need to drill a pilot hole first?

Yes. While the AB point is sharp enough to catch easily, it is not a drill bit. You must pre-drill a pilot hole (and ideally a countersink recess) into your material before driving the screw.

Can I use these screws for outdoor projects?

The BZP (Bright Zinc Plating) provides moderate corrosion resistance suited for indoor, dry, or sheltered environments. For fully exposed outdoor projects, we highly recommend using stainless steel self-tapping screws to prevent rust.
