S-92929A123 2-56 x 1" ASME B18.6.3 Plastic Slotted Flat Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance eliminates rust concerns in humid or chemical environments, extending service life
• Excellent electrical insulation properties prevent current leakage in electrical assemblies and sensitive equipment
• Wide operating temperature range from -40°F to 185°F ensures reliable performance in both freezing and elevated temperature conditions
• Class 2A thread fit with UNC coarse threading provides smooth, secure fastening with excellent engagement in plastic and soft materials
• Standard 100° countersink angle allows for flush mounting with minimal protrusion in streamlined assemblies
• RoHS 3 compliance ensures environmental safety and meets international regulatory requirements
• Full threading along 1" length offers maximum grip and adjustment flexibility throughout the fastener engagement

Professional Applications & Engineering Value

These nylon plastic flat head screws with UNC coarse threading solve critical engineering challenges in applications where metal fasteners would cause galvanic corrosion or electrical short circuits. The non-conductive properties make them ideal for electrical enclosures, control panels, and electronic assemblies where insulation is paramount. The 100° countersink design provides a clean, flush finish that prevents snagging in moving parts while maintaining structural integrity. With their exceptional chemical resistance, these screws perform reliably in harsh environments exposed to moisture, solvents, and industrial chemicals, making them perfect for marine equipment, chemical processing installations, and outdoor applications where traditional metal fasteners would deteriorate rapidly.

Specification Summary & Compliance

Manufactured to precise inch system dimensions with Class 2A thread fit tolerance ensuring consistent performance and interchangeability. These screws conform to ASME B18.6.3 specifications for dimensional accuracy and mechanical requirements. The UNC coarse thread profile (2-56) provides optimal performance in plastic and soft substrate applications. Compliance with RoHS 3 (2015/863/EU) confirms environmental responsibility and regulatory adherence for global manufacturing standards.
