Size: custom countersunk / drawing-based size
Description: PP flat-head screw for covers, plates, or sliding-contact areas where a raised head would interfere with movement or cleaning.
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.

PP Flat-Head Screw serves a specific maintenance problem rather than a generic accessory need. It is used as low-profile PP screw for surfaces that should remain flush, and the key selection condition is that use it when the screw head needs to sit close to the equipment surface after tightening.
The product works in PCB/FPC/LCD wet-process equipment where moisture, chemical mist, and long running cycles create strict fit requirements for flat-head screw components. A protruding screw head can catch panels, collect residue, or interfere with nearby moving parts. The PP Flat-Head Screw content should therefore keep model, material, and installation logic connected.
For PP Flat-Head Screw used as low-profile PP screw for surfaces that should remain flush, confidence comes from surface fit: the head profile, countersink area, and surrounding clearance decide whether the part is usable. QXY invites buyers to confirm countersink angle, thread, and head diameter because flat-head fit depends on the mating surface. The PP Flat-Head Screw quotation path for flush equipment covers should collect countersink shape, thread length, head diameter, and cover or plate thickness.
To provide high-precision, high-performance PCB equipment accessories, empowering the global electronics manufacturing industry to achieve efficient production.
