Professional Applications & Engineering Value

This 10-24 UNC shoulder screw is engineered to address critical alignment and durability challenges in industrial machinery, automation systems, and precision equipment. The 18-8 stainless steel construction, enhanced by a passivated finish, provides excellent resistance to oxidation and chemical exposure, making it ideal for environments where moisture or contaminants are present. The precise shoulder diameter and length ensure components are held securely with minimal play, reducing vibration-induced wear and maintaining accurate positioning over time. With a socket head and hex drive, installation is straightforward, allowing for high torque application without slippage. These features make the screw a trusted choice for heavy-duty applications such as pivots, guides, and rotating assemblies, where reliability and long service life are paramount.

Specification Summary & Compliance

This shoulder screw adheres to UNC coarse thread standards with a Class 2A thread fit for consistent engagement and ease of assembly. Shoulder dimensions are manufactured to tight tolerances: diameter within -0.001" to 0" and length from 0" to 0.002". The product conforms to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free of hazardous substances and suitable for global industrial supply chains.
