Size: custom thread / drawing-based size
Description: PP round-head screw for general wet-process fixing points where a smooth exposed head is safer than a sharp or raised metal fastener.
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 Round-Head Screw belongs in the Gears and Screws category because it supports machine stability at a very specific point: smooth exposed-head fastener for light-duty chemical-resistant assembly. Use around light-duty brackets, guards, and covers that need corrosion resistance but not heavy clamping force. The copy for PP Round-Head Screw should keep that real equipment role visible.
PCB horizontal lines often run in humid, chemically active environments, so dimensional matching and material selection for PP Round-Head Screw matter as much as the product name. A poor head choice can make maintenance awkward or leave an exposed point that catches gloves and cleaning cloths. This gives the PP Round-Head Screw page a stronger B2B purchasing angle.
For PP Round-Head Screw applied as smooth exposed-head fastener for light-duty chemical-resistant assembly, the useful trust point is safe exposed fastening, where the rounded head, PP material, and low-load use case match the cover or bracket. QXY focuses on head-style selection, chemical resistance, and custom size confirmation for existing machine positions. The PP Round-Head Screw inquiry for light-duty guard fixing should ask for thread size, head diameter, replacement quantity, and whether the screw sits in an operator-contact area.
To provide high-precision, high-performance PCB equipment accessories, empowering the global electronics manufacturing industry to achieve efficient production.
