Meridyen YHB Self-Drilling Screw 4.2×13 mm (Pack of 1000)
Increased Strength and Speed in Thin Metal Assembly
The Meridyen YHB (Half Countersunk Head) Self-Drilling Screw 4.2×13 mm is a short but reinforced diameter 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. The 4.2 diameter offers higher tensile and shear strength compared to the standard 3.9 diameter, ensuring a strong hold. The 13 mm length is ideal for short connection depths, especially at overlapping points of very thin sheets, accessory mounting, or wherever thickness is minimal. Its self-drilling (smart screw) design completely eliminates the need for pre-drilling.
Purpose and Key Features
The main purpose of the Meridyen YHB Self-Drilling Screw is to join two thin metal parts or a thin metal part to a thick metal frame, with increased strength, at high speed and with minimal effort.
Drill Point: The drill point at the tip of the screws allows for easy penetration through metal sheets and profiles up to 2-3 mm thick without the need for pre-drilling.
Half Countersunk Head (YHB): The underside of the head is flat, but its top surface is slightly domed. This design ensures the head sits aesthetically and flush on the surface after connection.
Reinforced Diameter (4.2): The 4.2 diameter can withstand higher torque values and provides a stronger connection compared to 3.9.
Size and Application Area:
4.2 Diameter x 13 Length: The 4.2 diameter ensures a strong hold, while the 13 mm length is designed for applications requiring the shortest connection depth. This avoids unnecessary length.
Surface Coating:
Typically zinc-coated to provide protection against rust and corrosion.
Areas of Use and Sectors
This screw is used in all metalworking and assembly applications requiring fast fastening, strong hold, and short connection depths.
