Professional Applications & Engineering Value
This precision shoulder screw is engineered from high-strength alloy steel to address critical challenges in machinery and equipment assembly. The 8-32 UNC coarse thread and Class 3A fit provide superior holding power, minimizing loosening under vibration—common in automotive, aerospace, and industrial automation. The headless slotted design allows for flush mounting in tight spaces, while the precisely controlled 3/16" shoulder diameter ensures accurate component positioning, reducing wear and extending service life. With a Rockwell C32 hardness, it withstands heavy loads and repetitive stress, making it a reliable fastening solution for pivots, guides, and rotating mechanisms where alignment and durability are paramount.
Specification Summary & Compliance
This shoulder screw features a Class 3A thread fit per UNC standards, with precise dimensional tolerances including a shoulder diameter of 3/16" (-0.001" to 0") and shoulder length of 3/8" (0" to 0.005"). Manufactured in accordance with industry specifications for alloy steel fasteners, it complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to environmental and safety standards for industrial use.
