S-94564A305 5/16"-18 x 1/2" Set Screws

Key Features & Benefits at a Glance

• Non-conductive and lightweight nylon plastic construction eliminates electrical conductivity risks and reduces assembly weight
• Corrosion-resistant material ensures long-term reliability in humid or chemically exposed environments without rust or degradation
• 5/32" hex drive design provides secure tool engagement for precise installation and removal with standard hex keys
• Class 2A thread fit with UNC coarse threading delivers consistent engagement and vibration resistance in various materials
• Flat tip configuration offers maximum surface contact for secure positioning of components on shafts or hubs
• Wide temperature tolerance (-40° to 185°F) maintains performance in both freezing and elevated temperature applications
• RoHS 3 compliance meets environmental regulations for hazardous substance restrictions in industrial markets

Professional Applications & Engineering Value

Engineered for applications where metal fasteners pose conductivity or corrosion concerns, this nylon plastic set screw provides exceptional electrical insulation while maintaining mechanical integrity. The UNC coarse thread profile and Class 2A fit ensure reliable engagement in plastics, soft metals, and composite materials, reducing stripping risks. The headless design with hex drive allows flush mounting in confined spaces, while the flat tip distributes clamping force evenly to prevent component damage. Ideal for electrical enclosures, consumer electronics, medical devices, and food processing equipment where non-metallic, corrosion-resistant fasteners are specified.

Specification Summary & Compliance

This set screw features 5/16"-18 UNC coarse threads with Class 2A dimensional tolerance per ANSI/ASME B1.1 standards, ensuring consistent thread engagement. The 1/2" length and 0.313" thread diameter provide standardized sizing for engineering drawings. Manufacturing complies with RoHS 3 (2015/863/EU) regulations, restricting hazardous substances for environmental safety. The right-hand thread direction and 5/32" hex drive conform to industry-standard installation practices.
