Cup point or flat point — which set screw should I use?

Decide by what the tip is allowed to do to the mating surface. The cup point (DIN 916) bites a shallow ring into the shaft and holds hardest against torque and reversal — the default for locking hubs, collars and gears on unhardened shafts. The flat point (DIN 913) spreads its clamp over a small flat ring face and leaves the surface nearly untouched — the choice for hardened shafts, adjusted positions or parts that are repositioned in service. Both run in the same 45H steel or A2/A4 stainless makings over the same M1.4–M24 thread range, so the point style, not the strength class, is the selection decision.

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.

What should an RFQ for these screws state?

State the standard designation (for example DIN 7991, DIN 916 or DIN 7985 — or the ISO designation your drawing prints), thread size and pitch, length or head dimension, strength class or material (such as 12.9, 45H, 4.8, A2-70, A4-80 or brass), finish (black oxide, zinc plated, or plain), required certificates such as a mill test report per EN 10204 3.1, and quantity per size — plus destination country.
