Professional Applications & Engineering Value
This 4-40 thread jack screw is engineered to address critical alignment and spacing challenges in precision assemblies. Constructed from 12L14 steel with a zinc yellow-chromate plating, it offers robust protection against oxidation and chemical exposure, making it ideal for electronics, machinery, and automotive components. The Class 2A/2B thread fit ensures minimal backlash and consistent torque transmission, reducing the risk of cross-threading in high-vibration environments. Its compact 3/16" hex size and controlled length tolerance facilitate easy integration into confined spaces, while the male-female thread configuration supports modular designs, enhancing assembly efficiency and structural integrity in industrial applications.
Specification Summary & Compliance
This jack screw adheres to inch system standards with a 4-40 thread size and Class 2A (external) / Class 2B (internal) thread fit, ensuring precise dimensional accuracy per industry norms. Key tolerances include hex size and length maintained within -0.005" to 0.005". The product conforms to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, affirming its compliance for safe use in regulated markets.
