Professional Applications & Engineering Value
This 10-24 UNC shoulder screw is engineered to address common challenges in precision assemblies, such as misalignment and component wear. The 18-8 stainless steel material provides exceptional corrosion resistance, ideal for machinery exposed to moisture or chemicals. With a 3/8" shoulder length and precise fit, it acts as a reliable pivot or spacer in applications like rotating shafts, linkages, and electronic enclosures, reducing the need for additional bushings. The low-profile socket head and slotted drive allow for compact designs and easy installation in tight spaces, while the coarse UNC threads ensure rapid assembly in production lines. Suitable for automotive, aerospace, and industrial equipment, this screw enhances operational efficiency and longevity.
Specification Summary & Compliance
This shoulder screw adheres to Class 2A thread fit and UNC thread standards for consistent dimensional accuracy. The shoulder diameter is 1/4" with a tolerance of -0.001" to 0", and the shoulder length is 3/8" with a tolerance of 0" to 0.002", ensuring precise assembly. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, confirming its suitability for regulated industrial and electronic applications.
