Introduce

The hex head of the hex washer head self-drilling screw is designed to be driven by a wrench or socket. However, these screws use their self-drilling (TEK) tips to penetrate their own holes and can pierce 20 to 14 types of metal at the same time. So their threads are also cut into the material for better retention, especially in wood.

Hex washer head from Huazhen Fasteners are used for sheet metal to sheet metal fastening. These screws come with features which help them in tackling the constraints of metal to metal fastening.  Since the hexagonal washer head self-drilling screw is heat-treated, its strength and retention capacity can be doubled. It is available in stainless steel, carbon steel, and alloy steel to bear more wear and tear while also making it more corrosion resistant. Since these screws are self-tapping, there is no need to drill a pilot hole before using them.

Hex Head Washer Self Drilling Screw

Feature

• The hexagon washer head screw is a self-piercing screw with a built-in washer at the screw head.
• Hex Head Washer Self Drilling Screw type can be easily identified by the point that imitates the appearance and function of the drill bit, so the tip allows the screw to be carved into metal and wood surfaces easily and smoothly without having to drill a separate pilot hole.
• The screw structure with full thread ensures that the screw can better distribute the tension and withstand greater force in a longer period of time.

Application Scenarios

• Solar panel installation
• Metal-to-metal fastening
• Metal and light steel framing
• Heavier gauge metal fastening applications
