Quotation

• The fastener family (ANSI B18.3 Hex Socket Set Screws, Flat Point) plus the standard designation from your drawing — DIN / ISO / JIS / ASTM / ANSI, or a drawing for custom parts.
• Size (diameter and length), thread type (metric or inch), property class or grade, and coating or finish.
• Quantity per size and your target delivery date.

Flat point or cup point — how should the choice be made?

Decide on two questions: will the screw ever be re-tightened, and what does it press against. The cup point bites a sharp ring into the shaft — maximum holding for a set-once joint, but it scars the surface and loses bite every time it is re-seated on the same mark. The flat point presses a defined circular face (d p) — no bite, but no damage either, which is why it is the choice for adjustable stops, parts that get repositioned, and any surface harder than the screw itself, where a cup would simply skip. If the joint sees vibration with a flat point, plan for a thread locker or a key, because the screw holds by friction alone. Compare the d p and d z columns at the same size and they are nearly identical — the geometry differs at the very tip, so the decision is service, not size.

What is the MOQ and lead time for these screws?

Minimum order quantity is 10,000 pieces per item. Stocked sizes ship in 3–7 days; non-stock diameters, lengths or finishes are quoted with a confirmed schedule. Common sizes in this designation are widely stocked — confirm the exact schedule against quantity and size mix at quotation.
