Key Features & Benefits at a Glance
- Exceptional durability with alloy steel construction and Rockwell C30 hardness for long-lasting performance in demanding environments.
- Superior corrosion resistance from the black oxide finish, extending service life and reducing maintenance needs.
- High tensile strength of 140,000 psi ensures reliable fastening under heavy loads and high-stress conditions.
- Precise Class 3A thread fit guarantees secure, vibration-resistant connections with minimal risk of loosening.
- Easy installation and removal with a low-profile socket head and hex drive, allowing for efficient assembly in tight spaces.
- Secure grip and handling thanks to the knurled head texture, preventing slippage during manual or tool-based adjustments.
- Broad compliance with industry standards including RoHS 3 and REACH, ensuring safety and environmental responsibility.
Professional Applications & Engineering Value
This alloy steel shoulder screw is engineered to address critical challenges in industrial settings, such as misalignment and component wear. The 10-24 UNC coarse thread and Class 3A fit provide excellent engagement and stability, reducing the risk of thread stripping in high-vibration applications like machinery assemblies and automotive systems. The black oxide finish enhances corrosion resistance, making it ideal for humid or chemically exposed environments. With a low-profile socket head and knurled texture, it offers easy access and secure handling in confined spaces, while the robust shoulder design supports precise alignment for pivots, bearings, and linkages, ensuring smooth operation and extended equipment life.
Specification Summary & Compliance
This shoulder screw adheres to UNC thread standards with a Class 3A fit for tight tolerances and reliable performance. Key dimensions include a thread diameter of 0.19", shoulder diameter of 1/4" (tolerance: -0.004" to -0.002"), and shoulder length of 5/8" (tolerance: -0.005" to 0.005"). It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free from hazardous substances and suitable for global industrial use.
