Round Head Self Drilling Screw | Custom OEM Fasteners

Round Head Self Drilling Screw technology has become essential for modern assembly because it combines drilling, tapping, and fastening in a single step. The round head design distributes clamping force evenly, reduces surface damage, and offers a finished appearance on panels, brackets, and housings. The self-drilling point is precisely milled so the screw penetrates metal sheets, wood, and composite materials without pre-drilling, improving productivity and reducing tool changes. For international customers, consistency is critical. Small variations in point geometry, thread pitch, or hardness can cause stripping, cam-out, or joint failure. Our production system integrates forging, cold heading, CNC machining, and stamping to maintain tight tolerances. The 630T and 300T forging machines form strong, defect-free heads, while multi-station cold heading machines shape threads and shanks efficiently. CNC lathes and machining centers refine critical dimensions, and turning-milling composite machines handle complex features. Surface treatment also affects performance. Zinc plating, black oxide, and passivation can improve corrosion resistance for outdoor or humid environments. We verify hardness, torque, and coating thickness to ensure the Round Head Self Drilling Screw performs reliably in construction, automotive, electronics, and general industrial applications. Whether you need a standard size or a fully customized non-standard fastener, our engineering team works with your drawings and samples to deliver the right solution.
