Professional Applications & Engineering Value

These 2-56 UNC thread shoulder screws deliver critical precision in applications requiring exact axial positioning and rotational stability. The 18-8 stainless steel composition provides excellent corrosion resistance, making them suitable for electronics, medical devices, and optical equipment where contamination must be avoided. The Class 3A thread fit ensures minimal backlash in precision mechanisms, while the knurled socket head prevents tool slippage during torque-sensitive assembly. With shoulder lengths from 0.13" to 1.99", engineers can select optimal bearing surfaces for pivots, spacers, and rotating components, solving alignment challenges in compact assemblies.

Specification Summary & Compliance

Manufactured to exacting standards with Class 3A thread fit and UNC coarse thread profile. Shoulder diameter maintains tight tolerance of -0.004" to -0.002" with length tolerance of ±0.002". Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. Right-hand thread direction with standard shoulder fit ensures compatibility with industrial fastening systems.
