Frequently Asked Questions
Q1: Are the free samples really free, including shipping?
A: Yes, we provide free samples for evaluation (usually 30-50 screws). Shipping costs may apply depending on your location; please contact our sales team for details.
Q2: What is the minimum order quantity (MOQ) for bulk purchases?
A: The MOQ for standard sizes is 500 boxes (each box contains 1,000 screws). For custom lengths or packaging, MOQ can be negotiated.
Q3: How long does delivery take?
A: For in-stock items, we ship within 7-15 days after payment. For custom orders, lead time is 20-30 days.
Q4: Can these screws be used with a manual screwdriver?
A: They are designed for collated screw guns. While manual use is possible, it is not recommended due to the strip format.
Q5: What is the advantage of black phosphate over other coatings?
A: Black phosphate provides good corrosion resistance and reduces driving torque compared to plain steel, making it suitable for indoor drywall applications.
Q6: Do you offer custom lengths or head types?
A: Yes, we offer customization for length, head type, and strip count. Please inquire with your requirements.
Q7: Are these screws compatible with drywall in high-humidity environments?
A: While black phosphate offers moderate protection, for extreme humidity we recommend our zinc-plated or stainless steel options (available upon request).
Q8: Can I get a certificate of analysis (COA) with each shipment?
A: Yes, a COA is provided upon request, detailing material hardness, coating thickness, and tensile strength.
