Key Features & Benefits at a Glance
- Non-conductive and corrosion-resistant nylon plastic ensures safe, reliable performance in electrical and corrosive environments without risk of galvanic corrosion.
- Hex drive (3/64") design provides secure tool engagement and high torque transmission, minimizing stripping and enabling easy installation in tight spaces.
- Headless construction with flat tip allows for flush mounting, preventing interference and maintaining a clean, unobstructed surface in assemblies.
- 4-40 UNC coarse thread with Class 2A fit offers quick assembly, excellent holding power, and consistent engagement in a variety of materials.
- Wide temperature resistance (-40° to 185°F) ensures dimensional stability and fastener integrity across diverse operating conditions.
- RoHS 3 compliance guarantees environmental safety and adherence to strict international regulations for hazardous substances.
- Right-hand coarse threading facilitates standard installation practices and secure fastening in plastic or soft material applications.
Professional Applications & Engineering Value
Engineered for precision fastening in sensitive and lightweight assemblies, this nylon plastic set screw with 4-40 UNC coarse thread and hex drive addresses common industrial challenges. Its headless, flat tip design ensures a smooth, flush finish, ideal for applications where protrusions are unacceptable, such as in consumer electronics, medical devices, and automotive interiors. The non-metallic material eliminates electrical conductivity and resists chemicals, making it perfect for insulating components or use in corrosive settings. With a broad temperature range, it maintains performance from freezing to elevated heat, providing reliable clamping force in dynamic environments without loosening or degradation.
Specification Summary & Compliance
This set screw adheres to UNC thread standards with a Class 2A thread fit for consistent accuracy and ease of assembly. It meets RoHS 3 (2015/863/EU) compliance, ensuring it is free from hazardous substances, and is manufactured to precise dimensional tolerances for reliable performance in industrial applications.
