Key Features & Benefits at a Glance
- Corrosion-resistant nylon construction ensures reliable performance in humid or chemical environments without rust or degradation.
- External hex head design provides excellent torque transmission for quick, secure installation with standard tools.
- Class 6g thread fit with coarse pitch delivers consistent engagement and vibration resistance in various materials.
- Wide temperature tolerance (-40° to 185°F) maintains structural integrity in both freezing and elevated temperature conditions.
- RoHS 3 compliance guarantees environmental safety and regulatory acceptance for international projects.
- Full threading along 20mm length maximizes grip strength and load distribution across the entire fastener.
- Lightweight off-white nylon material offers electrical insulation and UV resistance for outdoor or electronic applications.
Professional Applications & Engineering Value
Engineered for demanding B2B environments, these M4 nylon hex head screws solve critical fastening challenges where metal components fail. The metric coarse thread (0.7mm pitch) prevents cross-threading in soft materials while the Class 6g thread fit ensures precise alignment in automated assembly. Nylon plastic provides inherent electrical insulation for electronics enclosures and resistance to fuels/oils in automotive systems. The external hex drive enables high-torque installation without head stripping, making these fully threaded screws ideal for vibration-prone equipment, food processing machinery (non-corrosive), and outdoor fixtures where weight reduction and weatherability are prioritized.
Specification Summary & Compliance
This metric fastener features M4 x 0.7mm coarse threads with Class 6g manufacturing tolerance per ISO standards, ensuring dimensional accuracy for consistent performance. The 20mm length and 7mm hex head provide standardized proportions for replacement compatibility. Full compliance with RoHS 3 (2015/863/EU) is verified, meeting global environmental regulations for hazardous substance restrictions.
