Key Features & Benefits at a Glance
- Corrosion-resistant nylon plastic construction ensures reliable performance in humid or chemically exposed environments without rust or galvanic corrosion.
- Fine UNF 10-32 thread with Class 2A fit provides superior vibration resistance and precise engagement in metal or plastic components.
- 82° countersink angle and flat head design allows for flush mounting, reducing snag hazards and improving aesthetic finish.
- Wide operating temperature range (-40° to 185°F) maintains mechanical integrity in both freezing and elevated temperature applications.
- Full threading along the 1/2" length maximizes grip strength and load distribution across the entire fastener.
- ASME B18.6.3 compliance guarantees dimensional consistency and interchangeability with standardized components.
- RoHS 3 (2015/863/EU) compliance ensures environmental safety and suitability for electronics and regulated industries.
Professional Applications & Engineering Value
Engineered for precision assembly, these nylon plastic flat head screws with 10-32 UNF fine threads solve critical challenges in electrical enclosures, automotive trim, and consumer electronics. The non-conductive, lightweight material eliminates short-circuit risks and reduces overall assembly weight. The slotted drive facilitates quick installation with standard tools, while the 82° countersink ensures seamless integration into tapered seats—preventing loosening under dynamic loads. Ideal for corrosion-resistant fastening in marine, medical, or food-processing equipment, these screws deliver consistent clamping force without compromising dielectric properties.
Specification Summary & Compliance
This screw adheres to Class 2A thread tolerances per unified screw thread standards, ensuring precise fit with tapped holes. Manufacturing follows ASME B18.6.3 specifications for dimensional accuracy in head diameter (0.385"), length (1/2"), and thread geometry. The product is fully RoHS 3 (2015/863/EU) compliant, containing no restricted hazardous substances, and operates reliably within the specified temperature range of -40° to 185°F.
