Key Features & Benefits at a Glance
- Corrosion-resistant nylon construction ensures reliable performance in humid or chemical environments without rust or galvanic corrosion.
- Wide temperature tolerance from -40°F to 185°F maintains structural integrity in diverse operating conditions.
- External hex drive design provides secure tool engagement for efficient installation and removal with standard wrenches.
- Class 2A thread fit with UNC coarse threading delivers consistent, vibration-resistant fastening in general-purpose applications.
- RoHS 3 compliance guarantees environmentally safe manufacturing and suitability for regulated industries.
- Lightweight off-white plastic material reduces assembly weight while offering electrical insulation properties.
- Fully threaded 2-inch length enables maximum grip range and adjustment flexibility in various material thicknesses.
Professional Applications & Engineering Value
Engineered for demanding B2B environments, these nylon hex head screws solve critical challenges in electrical enclosures, marine equipment, and food processing machinery where metal fasteners would cause short circuits or contamination. The UNC coarse thread design prevents cross-threading during high-volume assembly while maintaining strong holding power in plastic and composite materials. With external hex drive compatibility, maintenance teams can achieve uniform torque distribution without specialized tools. The -40° to 185°F temperature range ensures dimensional stability in outdoor applications and thermal cycling conditions, making these RoHS compliant fasteners ideal for automotive components, HVAC systems, and consumer electronics requiring non-conductive, lightweight securing solutions.
Specification Summary & Compliance
This fastener maintains Class 2A thread fit tolerance per UNC standards with 1/4"-20 coarse threading and right-hand direction. Manufacturing adheres to inch system specifications with 3/8" head width and 3/16" head height dimensions. Regulatory compliance includes RoHS 3 (2015/863/EU) certification, ensuring restriction of hazardous substances in industrial components.
