Size: custom countersunk / drawing-based size
Description: This PP flat-head version is better described around clean surface clearance, especially where panels, covers, or operators pass near the fastening point.
Common Materials and Characteristics
Stainless Steel (SUS304/SUS316): Excellent corrosion resistance and high strength, suitable for chemical environments.
Titanium Alloy: Lightweight, high strength, and corrosion resistance, suitable for high-end equipment or specialized applications.
PP (Polypropylene): Lightweight, acid and alkali resistant, and chemically resistant, suitable for general corrosive environments and non-high-strength connections.
Common Types
Flat-head screws, round-head screws, and butterfly screws are available, depending on the equipment structure and assembly requirements.
General Parameters
Thread sizes range from M6 to M16, and lengths can be customized to meet installation requirements.

For PP Flat-Head Screw, the first selling point is fit control. It functions as flush PP fastener for sliding or exposed PCB equipment surfaces; suitable for exposed faces that should not have a tall screw head after assembly. Buyers comparing several similar products need this PP Flat-Head Screw distinction before they request price.
A small mismatch on PP Flat-Head Screw can create downtime even when the part looks correct in a photo. Using a round-head screw in this position may cause scraping, residue buildup, or poor cover seating. The expanded details for PP Flat-Head Screw move the inquiry from a vague product name to a confirmable spare-part request.
For PP Flat-Head Screw used as flush PP fastener for sliding or exposed PCB equipment surfaces, confidence comes from surface fit: the head profile, countersink area, and surrounding clearance decide whether the part is usable. QXY’s credibility comes from matching head style to installation environment, not selling every screw as the same product. The PP Flat-Head Screw quotation path for sliding-contact areas should collect countersink shape, thread length, head diameter, and cover or plate thickness.
