- Enhanced corrosion resistance from the black oxide finish, extending service life in various industrial environments.
- High-strength performance from alloy steel with Rockwell C45 hardness, ensuring reliable, long-term fastening under load.
- Secure, flush installation with a headless and hex drive design, ideal for confined spaces and providing a clean finish.
- Improved grip and alignment due to the extended tip design, which helps prevent component slippage.
- Wide compatibility with UNF fine threads (1/4"-28) for use in precision machinery and equipment requiring fine adjustments.
- Confident compliance with major industry standards including ASME B18.3, RoHS 3, and REACH for safe, regulated use.
Professional Applications & Engineering Value
This Black Oxide Alloy Steel Set Screw is engineered to solve critical challenges in industrial assembly, such as component slippage and vibration-induced loosening. Its headless design and hex drive allow for secure, flush mounting in tight spaces, while the extended tip bites into the shaft material to prevent rotational movement. The Class 3A UNF fine thread ensures a precise fit, reducing the risk of cross-threading and providing superior clamping force in precision machinery, automotive components, and power transmission systems. Made from high-strength alloy steel with a protective black oxide coating, it resists corrosion and maintains integrity under mechanical stress, making it a reliable choice for engineers seeking durability and performance in critical fastening applications.
Specification Summary & Compliance
This set screw adheres to Class 3A thread fit for high precision and is manufactured in accordance with ASME B18.3 specifications. It features a 1/4"-28 UNF fine thread with a right-hand direction and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material restrictions are met for industrial use.
