Key Features & Benefits at a Glance
- Superior vibration resistance with the nylon patch thread locker that maintains secure fastening even under dynamic loads.
- Exceptional strength and durability provided by alloy steel construction and a Rockwell C45 hardness, ensuring long-term reliability in demanding applications.
- Precise and secure fit due to the Class 3A external thread fit and UNC coarse threads, offering excellent holding power and easy assembly.
- Enhanced engagement and grip from the extended tip design, which improves contact and prevents loosening in critical assemblies.
- High-temperature performance with the thread locker rated for up to 250°F, suitable for environments with moderate thermal exposure.
- Reliable installation and removal using the 1/8" hex drive, allowing for efficient torque application in confined spaces.
- Compliance with industry standards, including ASME B18.3, ensuring consistent quality and interoperability in professional settings.
Professional Applications & Engineering Value
This alloy steel set screw is engineered to address common industrial challenges such as vibration-induced loosening and misalignment in machinery and equipment. The nylon patch thread locker provides a reliable locking mechanism without the need for additional adhesives, making it ideal for applications in automotive, aerospace, and manufacturing where maintenance access is limited. The extended tip ensures deeper penetration and improved clamping force on shafts and collars, while the UNC coarse threads and Class 3A fit deliver precise alignment and resistance to stripping. Made from high-strength alloy steel, it withstands heavy loads and repetitive stress, reducing downtime and enhancing safety in B2B procurement for critical assemblies.
Specification Summary & Compliance
This set screw features a 1/4"-20 UNC coarse thread with a Class 3A external thread fit for high precision, and dimensions including a 3/8" length and extended tip with specified tolerances. It complies with ASME B18.3 manufacturing standards and is certified RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, ensuring environmental safety and regulatory adherence for global industrial use.
