Diamond MDF Screw , Iran

The MDF Diamond screw features a unique thread geometry with a dual-pitch design for optimal performance. This screw incorporates sharp cutting threads with a 30-degree angle at its tip. Three diamond-shaped cutting grooves are positioned around the screw tip for clean material removal. These grooves cut through MDF particles without causing cracks or delamination. The first thread pitch is coarser than the second pitch for progressive engagement. The coarse pitch enables rapid entry into the MDF surface layer. The second finer pitch engages deeper within the material for secure holding. Threads continue along 80 percent of the screw shank length for maximum grip. The head type is a pan head with a four-lobed recess (Phillips or Pozidriv compatible).

The MDF Diamond screw is manufactured from medium carbon steel alloy with 0.35 to 0.45 percent carbon content. Heat treatment through hardening and tempering produces a surface hardness of 50 to 55 Rockwell C. A white or yellow chromate zinc coating with 8 to 12 microns thickness is applied as surface finish. This coating provides enhanced resistance against moisture from wood glues and adhesives. The 35-degree tip angle with 0.3 millimeter radius curvature prevents edge cracking of MDF panels. The maximum recommended installation torque for these screws ranges between 4 to 7 Newton meters. Primary applications include cabinet assembly, furniture front panels, and MDF frame construction.You can order and buy Diamond MDF Screw from Iran by contacting us through whatsaap and email.
