Chemical-Resistant Screws for Stable PCB Equipment Assembly In PCB wet-process machinery, screws must do more than fasten parts together. They must resist chemical corrosion, maintain clamping reliability, and allow repeatable maintenance without thread damage. QXY supplies PP, PVDF, PEEK, SUS, and titanium screws for etching, developing, cleaning, drying, and conveyor modules.
