Need Tapping Screws That Won't Strip Threads in Metal Building Materials?

Our 316 stainless steel bugle head tapping screws feature Type 17 thread cutting technology with four wings under the head for superior load distribution and vibration resistance. The hex socket drive prevents cam-out during high-torque installation, while the slotted tail ensures precise thread engagement in metal substrates. Contact us for custom specifications tailored to your construction hardware assembly requirements with full ISO compliance documentation.

Every fastener undergoes rigorous inspection protocols complying with ISO Working Instructions throughout the manufacturing process and before shipment. Our comprehensive quality control measures employ advanced inspection tools including calipers, protrusion-height gauges, micrometers, and 2.5D/2D projectors to verify critical dimensions such as head diameter, head height, hex slot depth, hex plug gauge specifications, thread length, major and minor diameters, thread angle, pitch, and the length of both pointed and slotted tails. With 45 years of manufacturing expertise and over 10,000 fastener products in our portfolio, we provide customized tapping screw solutions that meet the exacting standards of OEM manufacturers and aftermarket customers across diverse industrial sectors.
