Key Features & Benefits at a Glance
- Non-conductive and corrosion-resistant nylon plastic ensures electrical insulation and durability in harsh environments without rust or galvanic corrosion.
- Fine UNF thread spacing with Class 2A fit provides precise, secure fastening with reduced risk of loosening under vibration.
- 1/16" hex drive in a headless design allows for flush mounting in tight spaces and easy installation with standard tools.
- Wide temperature tolerance from -40° to 185°F maintains performance in both freezing and moderately high-heat conditions.
- Flat tip design delivers consistent clamping force without damaging shaft surfaces in positioning applications.
- RoHS 3 compliance guarantees environmentally safe use in regulated industries and electronics.
- Off-white color and lightweight nylon material offer aesthetic flexibility and reduced weight for sensitive assemblies.
Professional Applications & Engineering Value
This 6-40 UNF nylon set screw is engineered to address common industrial challenges such as component slippage, electrical conductivity risks, and corrosion in moist or chemical-exposed settings. The nylon plastic construction provides excellent dielectric properties, making it ideal for electrical enclosures, sensor mounts, and PCB assemblies where metal fasteners could cause short circuits. Its headless, right-hand thread design with a flat tip ensures minimal protrusion and even pressure distribution, protecting shafts and gears in precision machinery. With fine thread spacing and a Class 2A thread fit, it maintains tight tolerances in adjustment mechanisms and locking applications, reducing maintenance needs and enhancing operational reliability.
Specification Summary & Compliance
This set screw adheres to UNF thread standards with a Class 2A thread fit for consistent dimensional accuracy. It meets RoHS 3 (2015/863/EU) compliance, ensuring restriction of hazardous substances. Manufactured in the inch system, it features a 6-40 thread size, 1/4" length, and 1/16" hex drive, suitable for use in temperatures from -40° to 185°F.
