Cross Recessed Pan Head Self-Drilling Screws

Product  introduction

Made of carbon steel or stainless steel, cross recessed pan head self-drilling screws feature a flat and aesthetic pan head after installation. The cross recess fits common screwdrivers and power tools for easy operation. The self-drilling tail can penetrate metal, wood, etc. without pre-drilling, greatly improving installation efficiency, ideal for rapid on-site construction.

Carbon steel types, treated with galvanizing or Dacromet, are high-strength and cost-effective, suitable for general construction and industry. Stainless steel types (304/316, etc.) resist corrosion, ensuring stable use in humid, acidic/alkaline environments, often applied in outdoor projects and food equipment. Thread sizes range from ST2.9 to ST6.3, with lengths of 10 – 50mm, fitting various plate thicknesses. Widely used in steel structure construction, appliance assembly, automotive parts fixing, etc., they are produced according to GB standards, with professional selection services for reliable fastening.
