PP butterfly screw for wet-process covers and adjustment points that operators need to open or tighten by hand.
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 Butterfly Screw is built around tool-free PP screw for low-load covers and adjustment points. In practical use, best for low-load positions where fast manual access matters more than high torque. PP Butterfly Screw selection for tool-free PP screw for low-load covers and adjustment points 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 Butterfly Screw fail earlier than buyers expect when fit is wrong. Using a tool-tightened screw here can slow inspection work and make routine adjustment less convenient. For PP Butterfly Screw, the detail page therefore needs to make the exact use position and confirmation method clear.
For PP Butterfly Screw, trust starts with general tool-free fastening: the product is useful when a cover or fixture must be opened quickly without sacrificing PP corrosion resistance. QXY shows it can supply hand screws in sizes that match the customer’s existing equipment layout. Inquiry details should include thread size, grip clearance, removal frequency, and the chemical area where the screw will work.
