Professional Applications & Engineering Value

Engineered for precision motion control and rotational assemblies, this 316 stainless steel shoulder screw solves critical alignment challenges in industrial machinery, medical devices, and optical equipment. The precise shoulder fit with controlled diameter and length tolerances eliminates component wobble while providing accurate pivot points for gears, bearings, and linkages. The UNC coarse threads with Class 2A fit ensure rapid assembly and vibration resistance, while the passivated finish on 316 stainless steel delivers exceptional corrosion resistance in chemical, marine, and sterilization environments. The combination of 70,000 psi tensile strength and socket head design makes these shoulder screws ideal for high-stress applications requiring both precision alignment and reliable fastening integrity.

Specification Summary & Compliance

This precision shoulder screw maintains Class 2A thread fit per UNC standards with controlled shoulder diameter tolerance (-0.001" to 0") and shoulder length tolerance (0" to 0.002"). Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental compliance for industrial components. The inch-system measurements and standardized socket head profile guarantee interchangeability and consistent performance across precision assemblies.
