Professional Applications & Engineering Value
This 8-32 x 1/4" passivated 18-8 stainless steel rounded head Phillips screw is engineered to address common industrial challenges such as corrosion-induced failure and inconsistent thread engagement. The passivated surface treatment significantly enhances the natural corrosion resistance of 18-8 stainless steel, making it a superior choice for applications exposed to moisture, chemicals, or outdoor elements. Its UNC coarse thread design facilitates quicker assembly and reduces cross-threading risks, while the Class 2A thread fit ensures reliable performance in a wide range of pre-tapped holes. Commonly specified in electronics enclosures, machinery panels, and assembly lines, this screw provides a durable, corrosion-resistant fastening solution that maintains integrity over time, reducing maintenance needs and lifecycle costs.
Specification Summary & Compliance
This screw features a Class 2A thread fit per the UNC coarse thread standard, ensuring dimensional accuracy and interchangeability. It is manufactured in compliance with Fed. Spec. FF-S-92, QQ-P-35, and MS51957-41, confirming adherence to strict governmental and industrial manufacturing standards. The product is fully RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting current environmental and safety regulations for hazardous substances.
