Key Features & Benefits at a Glance
- Corrosion-resistant nylon construction ensures reliable performance in humid or chemically exposed environments without rust or degradation.
- Standard 100° countersink angle provides flush mounting for clean, professional finishes in wood, plastic, and composite assemblies.
- Class 2A coarse UNC threading delivers faster installation and superior holding power in soft materials while reducing cross-threading risks.
- Wide temperature tolerance (-40° to 185°F) maintains structural integrity in both freezing and high-heat industrial applications.
- Full threading along the 1-1/4" length enables adjustable grip depth and consistent clamping force across varied material thicknesses.
- ASME B18.6.3 compliance guarantees dimensional accuracy and interchangeability with standardized components.
- RoHS 3 certification ensures environmental safety and compliance with global hazardous substance restrictions.
Professional Applications & Engineering Value
Engineered for demanding industrial settings, these nylon plastic flat head screws combine electrical insulation with vibration dampening properties, making them ideal for electrical enclosures, automotive trim, and HVAC systems. The slotted drive accommodates standard tools for quick maintenance, while the coarse UNC 8-32 thread resists loosening under dynamic loads. With a -40° to 185°F operational range, they outperform metal alternatives in thermal expansion scenarios, preventing joint failure in temperature-cycling environments. The 100° countersink seamlessly integrates with chamfered holes, eliminating protrusions in visible assemblies.
Specification Summary & Compliance
This fully threaded 8-32 UNC screw adheres to Class 2A thread fit tolerances per ASME B18.6.3, ensuring precise engagement with mating components. Manufactured in accordance with inch system standards, it features a right-hand thread direction and standardized flat head profile. Compliance includes RoHS 3 (2015/863/EU) for hazardous substance restriction and ASME B18.6.3 for dimensional consistency in industrial fastener applications.
