Key Features & Benefits at a Glance
- Superior holding power with Class 3A thread fit for reliable, vibration-resistant fastening in demanding applications.
- Enhanced corrosion resistance from the black oxide finish on alloy steel, extending service life in various industrial environments.
- High-strength durability with a Rockwell C45 hardness rating, ensuring the screw withstands high stress without deforming.
- Secure and easy installation using a standard 3/16" hex key, providing a flush, headless design for space-constrained assemblies.
- Improved grip and alignment from the extended tip design, which helps prevent loosening under dynamic loads.
- Wide compatibility with 3/8"-16 UNC coarse threads, making it ideal for quick assembly and disassembly in common machinery.
- Regulatory peace of mind by meeting ASME B18.3 specifications and being RoHS 3 and REACH compliant for global use.
Professional Applications & Engineering Value
This 3/8"-16 UNC set screw is engineered to address critical challenges in industrial assembly, such as component slippage and joint failure under vibration. The black oxide alloy steel construction provides a protective layer against rust, while the Rockwell C45 hardness ensures the extended tip maintains its shape for repeated use in high-torque scenarios. Its headless design and hex socket drive allow for flush mounting in tight spaces, commonly used in securing gears, pulleys, and collars on shafts. By utilizing a Class 3A thread fit and coarse thread spacing, it offers quick installation and reliable performance in automotive, aerospace, and heavy machinery applications, reducing maintenance downtime and improving overall system integrity.
Specification Summary & Compliance
This set screw adheres to precise dimensional standards, including a Class 3A thread fit for tight tolerances and UNC thread type with a 3/8"-16 size. It is manufactured in compliance with ASME B18.3 specifications and meets regulatory requirements such as RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), ensuring environmental and safety standards are upheld for industrial use.
