S-94701A199 8-32 x 1" ASME B18.6.3 Plastic Slotted Flat Head Screws

Key Features & Benefits at a Glance

• Exceptional temperature resistance from -100°F to 500°F, ideal for extreme thermal cycling environments without performance degradation
• Superior chemical and corrosion resistance due to PTFE construction, ensuring long-term reliability in harsh industrial applications
• Precise Class 2A thread fit for smooth installation and secure fastening in UNC coarse threaded assemblies
• Standard 82° countersink angle enables flush mounting with common chamfered holes, improving aesthetics and safety
• Fully threaded design provides maximum grip length and uniform load distribution across the entire fastener
• Slotted drive compatibility allows installation with standard screwdrivers, reducing tooling requirements
• Regulatory compliance assurance with RoHS 3, REACH, and ASME B18.6.3 standards for global market acceptance

Professional Applications & Engineering Value

These PTFE plastic flat head screws deliver critical performance advantages in demanding industrial settings where metal fasteners fail. The white PTFE material provides inherent chemical resistance against aggressive solvents, acids, and bases while maintaining dimensional stability across the -100° to 500° F temperature range. The 8-32 UNC coarse thread configuration with Class 2A fit ensures reliable engagement in plastic and soft metal substrates, preventing stripping during assembly. The slotted drive design accommodates standard installation tools while the 82° countersink angle creates seamless flush finishes. These fully threaded screws are engineered for applications requiring non-conductive, non-corrosive fastening solutions in electrical enclosures, chemical processing equipment, food machinery, and laboratory instrumentation where material purity and temperature extremes are critical concerns.

Specification Summary & Compliance

This 8-32 UNC flat head screw features precise Class 2A thread fit per unified screw thread standards with coarse thread spacing and right-hand thread direction. Manufacturing compliance includes ASME B18.6.3 specifications for dimensional accuracy, along with full conformance to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The 1" length and standard flat head profile with 0.332" head diameter ensure compatibility with industry-standard counterbored holes and installation practices.
