Key Features & Benefits at a Glance
- Corrosion-resistant nylon construction eliminates rust concerns and provides excellent chemical resistance in demanding environments
- Full threading along the entire 1-1/4" length ensures maximum grip strength and uniform load distribution across joined materials
- Standard 82° countersink angle allows for flush mounting with minimal surface protrusion for cleaner finished appearances
- Wide operating temperature range (-40° to 185°F) maintains structural integrity across extreme thermal conditions
- Class 2A thread fit with UNC coarse threading delivers reliable engagement and faster installation in various materials
- ASME B18.6.3 compliance guarantees dimensional accuracy and interchangeability with industry-standard components
- RoHS 3 compliance ensures environmental safety and regulatory acceptance for international projects
Professional Applications & Engineering Value
These 8-32 UNC flat head slotted nylon screws provide critical solutions for applications where metal fasteners would cause galvanic corrosion, electrical interference, or weight concerns. The nylon plastic construction offers inherent electrical insulation properties while the fully threaded design maximizes pull-out resistance in plastic assemblies, electronic enclosures, and marine components. The standard 82° countersink angle ensures proper seating in chamfered holes, preventing surface damage while maintaining aerodynamic or hydrodynamic profiles. With temperature resistance from -40° to 185°F, these screws maintain dimensional stability in outdoor equipment, automotive interiors, and HVAC systems where thermal cycling would compromise lesser materials.
Specification Summary & Compliance
This flat head slotted screw features precise Class 2A thread fit with UNC coarse threading (8-32 size) in right-hand direction. Manufactured to ASME B18.6.3 specifications with 1-1/4" length and 0.164" thread diameter. Compliant with RoHS 3 (2015/863/EU) environmental standards, ensuring restriction of hazardous substances for global manufacturing applications.
