Key Features & Benefits at a Glance
- Superior corrosion resistance with 18-8 Stainless Steel construction, ideal for harsh environments and long-term reliability.
- Enhanced tamper resistance and torque transmission through the T27 Torx drive, reducing cam-out and tool wear.
- Permanent vibration resistance with factory-applied epoxy thread locker that cures to full strength in 72 hours.
- Wide temperature tolerance from -65°F to 400°F, ensuring performance stability in extreme conditions.
- High load-bearing capacity with 70,000 psi tensile strength and Rockwell B55 hardness for demanding applications.
- Precise, reliable fit due to Class 3A thread fit and UNC coarse threading, facilitating easier assembly and reduced cross-threading.
- Low-profile, rounded button head design provides a finished appearance and minimizes snagging in compact spaces.
Professional Applications & Engineering Value
Engineered for high-stakes industrial assemblies, these 1/4-20 UNC T27 Torx rounded head screws address critical challenges like vibration-induced loosening and environmental corrosion. The 18-8 Stainless Steel material offers excellent resistance to rust and chemicals, making them suitable for outdoor equipment, automotive subsystems, and electronic enclosures. The epoxy thread locker is pre-applied, eliminating the need for manual adhesive application and ensuring a secure, permanent bond that hardens fully within 72 hours. This combination of Class 3A thread precision and coarse thread spacing allows for quick installation and high clamp force retention, reducing maintenance and downtime in production lines and machinery.
Specification Summary & Compliance
This fastener features a 1/4"-20 UNC thread with Class 3A fit for superior dimensional accuracy and fully threaded design. It adheres to industry standards for right-hand coarse threading and includes critical compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material restrictions are met for global supply chains.
