Custom Drill-Point Screws with Serrated Underside | Hetai
Precision Custom Fasteners for Wood, Metal & Industrial Applications
Hetai manufactures Custom Drill-Point Screws with Serrated Underside, combining a precision drill-point tip with specially engineered serrations beneath the screw head. Designed for demanding fastening applications, these screws offer efficient drilling performance together with enhanced holding power and secure head seating.
As a professional custom fastener manufacturer in China, Hetai produces non-standard drill-point screws according to customer drawings, samples, and OEM/ODM specifications for furniture, woodworking, sheet metal, construction, automotive, and industrial equipment.
What Are Drill-Point Screws with Serrated Underside?
A drill-point screw features a drill-shaped tip that can drill and tap into the workpiece during installation, reducing or eliminating the need for pre-drilling in many applications.
The serrated underside consists of precision-cut serrations beneath the screw head. These serrations bite into the surface material during tightening, helping improve grip and reduce loosening caused by vibration or movement.
This combination provides both fast installation and strong, reliable fastening performance.
