Frequently Asked Questions
Q: Do self-tapping screws require a pre-drilled pilot hole?
A: Yes, in most metal and hard plastic applications, a pre-drilled pilot hole is required. The hole size should be slightly smaller than the screw's outer thread diameter to allow the threads to engage securely.
Q: What is the difference between self-tapping and self-drilling screws?
A: Self-tapping screws tap their own threads but typically require a pre-drilled pilot hole. Self-drilling screws feature a drill-bit-shaped point that drills its own hole and cuts threads in a single operation, eliminating the need for prep work.
Q: What materials are your self-tapping screws made of?
A: We offer self-tapping screws made from high-tensile Carbon Steel (hardened C1022A) and premium Stainless Steel grades (SS304, SS316, and SS201) to suit different environmental requirements.
Q: Can I customize the head shape, drive type, and surface treatment?
A: Absolutely. We offer fully customizable solutions, including Pan, Flat, Truss, Hex, and Oval head types, along with standard surface finishes like Zinc Plated, Black Oxide, Nickel Plated, Ruspert, and Dacromet.
Q: What is the standard packaging and lead time for bulk orders?
A: We offer bulk cartons and small box packaging, with OEM options for custom logos. Our standard manufacturing lead time is 7 to 25 days depending on specifications, shipping out from Tianjin Port, China.
