Frequently Asked Questions (FAQ)
-
What makes 410 stainless steel different from 304 or 316?
410 is a martensitic stainless steel that can be heat-treated to achieve higher hardness, making it more suitable for cutting and drilling applications. It has moderate corrosion resistance, less than 304/316, but adequate for many indoor and sheltered outdoor uses. -
Do these screws require pre-drilling?
No. They are self-drilling, meaning the tip acts as a drill bit and creates its own pilot hole as you drive the screw. However, for very thick or hard materials, pre-drilling a small pilot hole may be recommended. -
What is the maximum thickness of metal these screws can penetrate?
It depends on the screw size. For example, #12 size can typically drill through up to 5mm (0.2") of mild steel. Larger sizes can drill thicker material. Contact us for specific recommendations. -
Is the 1-year warranty covering all defects?
The warranty covers manufacturing defects such as cracks, improper heat treatment, or thread imperfections. It does not cover damage from misuse or improper installation. A mill test report can be provided for material verification. -
Can I get a mill test report for my order?
Yes, mill test reports are available upon request. Please mention this requirement when placing your order. Additional lead time may be needed for testing and documentation. -
Do you offer custom sizes or packaging?
Absolutely. We can customize lengths, diameters, and packaging (private label, specific box sizes). Minimum order quantities may apply. -
What is the typical lead time?
For standard sizes in stock, we can ship within 7-15 days after order confirmation. Custom orders may take 20-30 days depending on quantity and specifications. -
How are these screws packed for export?
Generally in sturdy cartons or wooden pallets, with inner protection to prevent damage during transit. We follow your shipping requirements (FOB, CIF, etc.).
