Key Features & Benefits at a Glance
- Superior corrosion resistance with 18-8 stainless steel construction and passivated finish, ensuring long-term reliability in harsh environments.
- Exceptional mechanical strength offering 70,000 psi tensile strength and Rockwell B55 hardness for high-load applications without failure.
- Precise alignment and smooth rotation due to the exact 1/4" shoulder diameter and smooth head texture, reducing wear in assemblies.
- Secure, reliable fastening with Class 2A thread fit and fine UNF thread spacing, minimizing loosening under vibration.
- Easy installation and removal using the standard hex socket head design with 1/8" drive size, saving time in maintenance.
- Compliance with global standards including RoHS 3 and REACH, making it suitable for regulated industries like electronics and automotive.
- Consistent dimensional accuracy with tight shoulder tolerances (e.g., -0.001" to 0" diameter), ensuring repeatable performance in precision machinery.
Professional Applications & Engineering Value
This 10-32 UNF precision shoulder screw is engineered to address critical challenges in industrial assemblies, such as misalignment and component wear. Made from 18-8 stainless steel with a passivated finish, it resists corrosion in moist or chemical-exposed settings, extending service life in applications like robotics, conveyor systems, and precision instruments. The Class 2A thread fit and fine thread spacing provide vibration resistance, while the precise shoulder diameter and length ensure accurate positioning of parts like bearings or gears. Its socket head design allows for compact installation in tight spaces, reducing assembly time and improving overall efficiency in B2B manufacturing environments.
Specification Summary & Compliance
This shoulder screw adheres to UNF thread standards with a Class 2A thread fit for precise engagement. Dimensions include a 1/4" thread length and 1/8" shoulder length, with tight tolerances (e.g., shoulder diameter: -0.001" to 0"). It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free from hazardous substances for use in electronics and other regulated sectors.
