Key Features & Benefits at a Glance
- Secure vibration-resistant locking with an integrated nylon patch that maintains hold from -50° to 250° F, reducing maintenance in dynamic environments.
- Exceptional corrosion resistance thanks to 18-8 stainless steel and a passivated finish, ideal for harsh or washdown applications.
- High-strength durability with a tensile strength of 70,000 psi and Rockwell B55 hardness for reliable performance under load.
- Precision alignment and spacing ensured by the 1/4" shoulder diameter with tight tolerances and Class 3A thread fit.
- Easy installation and removal using a standard hex socket drive, providing efficient assembly in confined spaces.
- Broad industrial compliance meeting ASME B18.3 standards and RoHS/REACH regulations for global sourcing and safety.
- Stable coarse threading with UNC 10-24 right-hand threads for quick engagement and strong holding power.
Professional Applications & Engineering Value
This 10-24 UNC shoulder screw is engineered to address common industrial challenges like misalignment, vibration loosening, and corrosion. The 1/4" shoulder diameter with precise tolerance control acts as a reliable pivot or spacer in assemblies, preventing component shift in machinery, automotive, and electronics. Made from 18-8 stainless steel with a passivated finish, it resists rust and chemical exposure, extending service life in demanding environments. The integrated nylon patch thread locker secures fastenings against shocks and temperature fluctuations from -50° to 250° F, reducing downtime. Ideal for applications requiring high tensile strength and Class 3A thread fit, this screw ensures consistent performance in precision equipment, conveyor systems, and robotic arms, where reliability is critical.
Specification Summary & Compliance
This shoulder screw features a Class 3A thread fit for high precision, with UNC 10-24 coarse threads and a right-hand direction. Dimensions include a shoulder diameter of 1/4" (tolerance: -0.004" to -0.002") and thread length of 3/8". It complies with ASME B18.3 manufacturing standards and is RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliant, ensuring environmental safety and quality in industrial use.
