Frequently Asked Questions (FAQ)
-
Q: What is C1022A carbon steel?
A: C1022A is a low-carbon steel grade with about 0.22% carbon content, often case-hardened to provide a tough exterior while maintaining core ductility. It is commonly used for drilling screws due to its improved strength after heat treatment. -
Q: Are these screws suitable for stainless steel or aluminum?
A: These carbon steel screws work well with most steel substrates. For aluminum or softer metals, we recommend a compatible coating to prevent galvanic corrosion. Optional surface finishes are available. -
Q: Do you offer custom sizes?
A: Yes, we can produce full-size ranges, including custom lengths and diameters. Please provide your specifications for a quotation. -
Q: What does “No Snapping” mean?
A: It means the screws are engineered to resist head separation or shank fracture under typical torque and load conditions. While no product is indestructible, our heat treatment process reduces the risk significantly. -
Q: Is the warranty applicable to all orders?
A: Warranty terms are available for bulk orders. Please contact our sales team for details on coverage and claim procedures. -
Q: How are the screws packaged for international shipment?
A: Bulk packing is standard – screws are packed in cartons then on pallets. We can also arrange small retail packaging if required (MOQ may apply). -
Q: What is the lead time for large orders?
A: Typical lead time is 15–30 days depending on size and quantity. Rush orders may be expedited upon request.
