Key Features & Benefits at a Glance
- Enhanced manual torque application with high-profile round head and knurled texture for secure, slip-resistant grip in tight spaces
- Corrosion-resistant Nylon Plastic construction ensures reliable performance in humid or chemical environments without rust or galvanic corrosion
- Precise Class 2A thread fit provides smooth engagement and vibration resistance in 10-32 UNF fine-threaded applications
- Wide temperature tolerance from -40° to 185° F maintains structural integrity in both industrial and outdoor settings
- Full threading design offers consistent clamping force along the entire 3/8" length for uniform load distribution
- RoHS 3 compliance guarantees environmental safety and regulatory acceptance for international supply chains
- Dual drive compatibility through slotted drive and thumb head allows both tool-assisted and manual installation flexibility
Professional Applications & Engineering Value
Engineered for repeated access panels and calibration covers, this 10-32 UNF nylon thumb screw solves common corrosion and electrical isolation challenges in electronics enclosures, medical devices, and outdoor equipment. The knurled high-profile head delivers maximum hand-tightening torque without specialized tools, while the Nylon material eliminates thread galling and provides dielectric properties for electrical applications. With 11,000 psi tensile strength and fine UNF threading, it maintains secure fastening in vibration-prone assemblies where metal screws would loosen or cause short circuits. The fully threaded design ensures consistent engagement depth across varying material thicknesses.
Specification Summary & Compliance
Manufactured to UNF 10-32 thread specifications with Class 2A tolerance for precise fit in standard threaded inserts and tapped holes. The 13/32" head diameter and 5/16" head height provide optimal surface contact for hand tightening. Compliant with RoHS 3 (2015/863/EU) regulations, containing no restricted hazardous substances. The right-hand fine threading follows ASME B1.1 standards for unified screw threads.
