Professional Applications & Engineering Value
This precision shoulder screw is engineered to address common industrial challenges such as misalignment, vibration loosening, and corrosion in machinery. The 18-8 stainless steel material provides excellent durability against moisture and chemicals, while the nylon patch locking feature maintains clamp load under thermal cycling and dynamic stresses. With a Class 2A thread fit and fine 10-32 UNF thread, it ensures accurate positioning in assemblies like rotating shafts, bearings, and linkages, reducing maintenance needs. The socket head design with 1/8" hex drive allows for efficient torque application in confined spaces, making it a reliable choice for automotive, aerospace, and manufacturing equipment where high tensile strength and precision are critical.
Specification Summary & Compliance
This shoulder screw adheres to Class 2A thread fit and UNF fine thread standards for dimensional accuracy, with precise shoulder diameter and length tolerances. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free from hazardous substances. Manufactured to deliver consistent performance with a tensile strength of 70,000 psi and hardness of Rockwell B55, it is suitable for rigorous industrial applications requiring reliability and safety.
