S-92929A121 2-56 x 3/4" ASME B18.6.3 Plastic Slotted Flat Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance ensures long-lasting performance in harsh environments without rust or degradation
• Excellent electrical insulation properties prevent current leakage and short circuits in sensitive electronic applications
• Wide temperature tolerance from -40° to 185°F maintains structural integrity across diverse operating conditions
• Class 2A thread fit precision guarantees consistent engagement and reliable fastening in assembly operations
• 100° countersink angle design provides flush mounting and streamlined surface profiles
• Full threading along the 3/4" length offers maximum grip strength and adjustment flexibility
• RoHS 3 compliance meets international environmental standards for hazardous substance restrictions

Professional Applications & Engineering Value

These nylon plastic flat head screws with 2-56 UNC coarse threading solve critical engineering challenges where metal fasteners fail. The non-conductive nylon material eliminates electrical conductivity risks in panel mounting, electronic enclosures, and instrumentation assemblies. The 100° countersink angle and slotted drive enable precise flush installation in confined spaces while maintaining aesthetic surface finishes. Ideal for corrosive environments like chemical processing equipment or marine applications, these screws withstand moisture, chemicals, and temperature fluctuations that would compromise metal alternatives. The fully threaded design ensures maximum thread engagement across the entire 3/4" length, providing superior holding power in plastic, composite, and soft material applications where strip-out resistance is crucial.
