Key Features & Benefits at a Glance
- Corrosion-resistant nylon construction ensures reliable performance in humid or chemical environments without rust or degradation
- Wide temperature tolerance (-40° to 185°F) maintains structural integrity across diverse industrial and outdoor applications
- Class 2A thread fit with UNC coarse threading provides secure fastening with excellent vibration resistance and quick assembly
- 100° countersink angle with standard flat head profile enables flush mounting for streamlined surfaces and reduced snagging hazards
- Full threading along 1/4" length maximizes grip strength and load distribution across joined materials
- ASME B18.6.3 compliance guarantees dimensional accuracy and interchangeability with standardized components
- RoHS 3 (2015/863/EU) compliance ensures environmental safety and regulatory acceptance for global supply chains
Professional Applications & Engineering Value
Engineered for precision assemblies requiring electrical insulation and chemical resistance, these nylon plastic flat head screws solve critical challenges in electronics enclosures, food processing equipment, and marine components. The slotted drive style accommodates standard tools while the right-hand UNC coarse threads prevent cross-threading during high-volume production. With a temperature range spanning -40° to 185°F, these fasteners maintain clamp force in thermal cycling environments where metal alternatives would fail due to galvanic corrosion or thermal expansion mismatches. The fully threaded design ensures consistent engagement in variable material thicknesses, reducing inventory complexity for maintenance teams.
Specification Summary & Compliance
Manufactured to ASME B18.6.3 specifications with Class 2A thread fit tolerances for reliable interchangeability. The UNC 1/4"-20 coarse thread pattern adheres to inch-system standards while the 100° countersink angle conforms to industry profiles. Compliant with RoHS 3 (2015/863/EU) environmental directives and suitable for applications requiring non-conductive, non-magnetic fastening solutions.
