Engineered to withstand extreme environments, low temperatures, chemical exposure, and high mechanical stress
In structural design, mechanical fastening systems represent the primary point of force transfer. Among these, Custom Self-Tapping Tek Screws (also referred to as self-drilling screws) are critical components that merge three distinct manufacturing phases into a single application step: drilling, thread-forming, and securing. Unlike standard fasteners that require pre-drilled pilot holes, Tek screws incorporate a specialized drill point designed to displace, drill, and tap parent metal elements ranging from cold-rolled steel framing to heavy-duty structural structural structural steel columns.
As a premier global exporter, Beiersdorf Industrial Technology integrates high-level material science and mechanical optimization to address the exact demands of heavy industries. Selecting the correct Tek screw requires a deep understanding of drill point geology (Tek 1 to Tek 5), metallurgical composition, and surface plating properties.
Utilizing high-grade carbon steel, specialized alloy configurations, titanium blends, and friction-welded bi-metal structures (Grade 304/316 + SAE 1022) to handle heavy-duty steel penetrations up to 15mm thick.
Precisely calibrated Tek 1, Tek 3, Tek 4, and Tek 5 drilling flutes designed to manage thermal energy accumulation, clear metal chips efficiently, and prevent point fracture under high RPM loads.
Engineered protective layers, including mechanical zinc platings, multi-layer Ruspert finishes, and Zinc-Nickel coatings, rated to withstand over 1,500 hours of ASTM B117 salt spray exposure.
Understanding mechanical limit states is critical to preventing joint failure, shear rupture, and thread stripping. The following reference table outlines typical engineering configurations for high-strength custom self-drilling Tek screws:
| Screw Designation | Point Type | Material Core | Max Drilling Capacity (Steel) | Recommended Installation Speed | Ultimate Shear Strength (kN) | Tensile Pull-out Strength (kN) |
|---|---|---|---|---|---|---|
| M4.8 (No. 10) Tek 3 | Tek 3 Standard | SAE 1022 / Bi-Metal 304 | 1.5 mm - 3.5 mm | 1,800 - 2,500 RPM | 7.2 kN | 9.5 kN |
| M5.5 (No. 12) Tek 3 | Tek 3 Standard | SAE 1022 / Bi-Metal 316 | 1.75 mm - 4.5 mm | 1,500 - 2,000 RPM | 10.8 kN | 12.4 kN |
| M5.5 (No. 12) Tek 5 | Heavy Duty Tek 5 | Carbon Steel (Heat Treated) | 4.0 mm - 12.5 mm | 1,000 - 1,500 RPM | 12.1 kN | 15.6 kN |
| M6.3 (No. 14) Tek 5 | Heavy Duty Tek 5 | Carbon Steel / Bi-Metal 304 | 4.0 mm - 15.0 mm | 800 - 1,200 RPM | 16.5 kN | 19.8 kN |
