Detailed Product Overview

These self-drilling fasteners are manufactured from high-quality SUS410 stainless steel, a martensitic grade specifically selected for its unique ability to be heat-treated to an exceptionally high Rockwell hardness. Unlike standard 300-series stainless steel, which is too soft to pierce metal efficiently, our SUS410 screws feature a precision-forged drill point that cuts through steel plate and aluminum sheets smoothly and rapidly, reducing installation time and worker fatigue. The classic pan head design provides a low-profile, clean aesthetic with a flat under-head surface that maximizes surface contact and clamping pressure across the fastened material, preventing pulling or warping. Technically, the deep Phillips drive recess is engineered to resist cam-out under high torque, ensuring stable engagement with automated power drivers on busy production lines. Offering an optimal balance of structural strength, wear resistance, and reliable atmospheric corrosion protection, these customizable M2.9 to M6.3 fasteners provide a professional-grade fastening solution for metal-to-metal framing, HVAC installations, roofing, and general industrial assembly.

Key Features

• High-Hardness SUS410 Alloy: Heat-treated martensitic stainless steel provides the superior mechanical strength and hardness required to drill through metal sheets efficiently.

• Integrated Self-Drilling Point: Eliminates the need for separate drilling and tapping operations, streamlining construction workflows and lowering labor costs.

• Low-Profile Pan Head Design: Features a wide, rounded head with a flat bearing surface that distributes clamping load evenly without damaging the substrate.

• Precision Phillips Drive: Engineered deep recess ensures a secure fit with driver bits, minimizing slippage and protecting the screw head during high-speed installation.

• Extensive Size Matrix: Available in thread diameters ranging from M2.9 up to M6.3, accommodating diverse material thicknesses and structural requirements.
