Key Features & Benefits at a Glance
- Superior vibration resistance with integrated Nylon Patch thread locker that maintains secure locking even under dynamic loads
- Exceptional temperature tolerance from -50°F to 250°F, ensuring reliable performance in extreme industrial environments
- Enhanced durability and corrosion resistance through Black-Oxide coated Alloy Steel with Rockwell C45 hardness
- Precise, fine-thread engagement with Class 3A UNF threads for tighter fit and reduced loosening in critical assemblies
- Easy installation and removal using standard 5/32" hex drive, ideal for confined spaces with its headless design
- Cup point design provides strong biting action into shafts and components for permanent positioning
- Compliance with major industrial standards including ASME B18.3 and ASTM F912 for guaranteed quality and interoperability
Professional Applications & Engineering Value
This Black-Oxide Alloy Steel set screw addresses critical vibration-induced loosening challenges in industrial machinery, automotive components, and precision equipment. The Nylon Patch thread locker technology creates consistent friction that resists rotational forces without requiring additional adhesives, while the Class 3A UNF fine threads deliver superior clamping force distribution. The cup point tip bites securely into mating surfaces, preventing axial movement in pulley systems, gear assemblies, and coupling applications. Engineered for demanding environments, this headless hex drive set screw combines high-strength Rockwell C45 hardness with chemical-resistant Black-Oxide treatment, making it suitable for both high-temperature manufacturing processes and low-temperature operational conditions.
Specification Summary & Compliance
This set screw features 5/16"-24 UNF fine threads with Class 3A precision tolerance for exact fitment, measuring 5/8" in length with 5/32" hex drive. Manufactured to ASME B18.3 specifications and ASTM F912 standards, ensuring dimensional accuracy and mechanical properties. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, confirming safe use across global industrial markets.
