Size: custom thread / drawing-based size
Description: Round-head PP screw for protective covers where the buyer wants a neat exposed finish and resistance to wet-process chemicals.
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 is built around PP cover screw for protective housings and light fixtures. In practical use, best used on covers that are opened occasionally and should remain easy to identify during maintenance. PP Round-Head Screw selection for PP cover screw for protective housings and light fixtures depends on custom thread / drawing-based size, material choice, mounting position, and the buyer’s real equipment environment rather than product appearance alone.
For PCB wet-process equipment, chemical exposure, humidity, and repeated maintenance can make PP Round-Head Screw fail earlier than buyers expect when fit is wrong. Generic fastener copy will not explain why this product fits cover work better than flat or external-hex alternatives. For PP Round-Head Screw, the detail page therefore needs to make the exact use position and confirmation method clear.
For PP Round-Head Screw applied as PP cover screw for protective housings and light fixtures, 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 make the page more convincing by showing how screw head selection follows actual equipment use. The PP Round-Head Screw inquiry for protective cover fastening 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.
