Meridyen YHB Self-Drilling Screw 3.9×16 mm (Pack of 1000)
High Performance in Medium-Depth Thin Metal Fastening
The Meridyen YHB (Countersunk Head) Self-Drilling Screw 3.9×16 mm is a medium-sized and versatile fastener designed for securing materials such as thin metal sheets, sheet metal panels, and light steel profiles to each other or to thicker metal surfaces. Its 3.9 diameter ensures a strong hold with a quick and minimal pilot hole, while its 16 length is ideal for medium connection depths, such as joining two sheet metal panels, mounting accessories, or fastening metal to a wooden frame. Its self-drilling (smart screw) design completely eliminates the need for pre-drilling.
Purpose and Key Features
The primary purpose of the Meridyen YHB Self-Drilling Screw is to firmly join two thin metal pieces, or one thin metal piece to a medium-thickness metal frame, with high speed and minimal effort.
Drill Point: The drill point at the end of the screws allows for easy penetration through metal sheets and profiles up to 2-3 mm thick without the need for pre-drilling.
Countersunk Head (YHB): The underside of the head is flat, but the top surface is slightly domed. This design ensures that the head sits flush and aesthetically pleasing on the surface after fastening, and it fully seats into the mounting surface.
Size and Application Area:
3.9 Diameter x 16 Length: The 3.9 diameter provides sufficient holding strength, while the 16 length is ideal for applications requiring the most commonly used medium connection depth.
Thread Structure:
The fine and sharp thread structure ensures a tight grip on the surface and prevents loosening.
Surface Coating:
Typically zinc-coated to provide protection against rust and corrosion.
Areas of Use and Industries
This screw is used in all metalworking and assembly applications requiring quick fastening, strong hold, and medium connection depth.
