Speed up your metal-to-metal and plastic assemblies with our Hex Head Self-Tapping Screws. Supplied in a convenient trade pack of 100, these robust fasteners feature a sharp Type AB point to effortlessly cut its own mating thread and a solid hexagon head for slip-free, high-torque driving. Finished in Bright Zinc Plating (BZP) for excellent indoor corrosion resistance, they are an absolute staple for HVAC installation, automotive bodywork, and general sheet metal fabrication where a secure, vibration-resistant hold is required

Feature Icon
High-Torque Hex Head: Allows for maximum driving force using a socket or magnetic nut setter without the risk of driver cam-out or stripping.

Sharp AB Point: Specially designed to catch instantly and tap its own precise, fine thread into pre-drilled sheet metal and plastics
Feature Icon
Corrosion Resistance: Finished in Bright Zinc Plating (BZP) to protect against oxidation and rust in dry and indoor environments.

Maximum Torque, Zero Slip

When driving fasteners into tough sheet metal, standard Phillips or slotted drives can easily slip out (cam-out) under heavy pressure, damaging the screw head or scratching your workpiece. The solid hexagon head on these self-tapping screws solves that problem entirely. By using a standard hex socket or a magnetic nut setter, your tool grips the outside of the fastener, providing a massive surface area for torque transfer. You can safely apply significantly more rotational force, making these screws ideal for heavy-duty structural assemblies and high-speed manufacturing.

Precision Tapping with AB Points

The Type AB point is the industry standard for joining thin sheet metal, resin, and brittle plastics. It combines a sharp, gimlet point with fine, closely spaced threads. After drilling a suitably sized pilot hole, the sharp tip catches the edge of the material instantly. As the screw is driven home, the hardened steel threads act like a mechanical tap, carving a perfectly matched mating path directly into the substrate. This creates a secure, custom-fit friction lock that won't easily vibrate loose over time.

Reliable BZP Protection

Manufactured from high-strength hardened steel, these screws are built to handle the rigorous demands of professional fabrication. To protect the core material, they are coated in a Bright Zinc Plating (BZP). This clean, silver-coloured finish acts as a sacrificial barrier against oxidation, keeping your indoor assemblies, HVAC ducting, and internal automotive panels rust-free and structurally sound for years to come.

Key Features

  • Single-Sided Assembly: Perfect for blind holes or enclosed box sections where you cannot access the back of the material to fit a nut.
  • Slip-Free Driving: The six flat sides of the hex head ensure a secure tool grip, making them highly preferred for automated or high-speed impact driving.
  • Type AB Thread: Features a sharp locating point and finer threads compared to standard Type A screws, providing superior grip and reducing the risk of tearing thin materials.
  • Durable Steel Core: Hardened construction ensures the screw can withstand the intense friction and torque required to tap directly into metal substrates.
  • Trade Pack Size: Supplied in heavy-duty boxes of 100 pieces, perfect for keeping your work van or workshop fully stocked for the week ahead.

Frequently Asked Questions

Do I need to drill a pilot hole first?

Yes. While the AB point is very sharp to help it start tapping easily, it is not a drill bit. You must pre-drill a correctly sized pilot hole into your sheet metal or plastic before driving the screw.

Do these screws come with an attached washer?

No, these are standard hex head screws without an integrated washer. If you need a built-in washer to help spread the clamping load over thin materials, you should look for our "Hex SEMS" self-tapping screws instead.

Can I use BZP screws for outdoor projects?

Bright Zinc Plating (BZP) offers moderate corrosion resistance suited for indoor, dry, or sheltered environments. If your project will be fully exposed to outdoor weather and rain, we highly recommend upgrading to stainless steel self-tapping screws to prevent rust.
