Professional Applications & Engineering Value
This 6-32 UNC set screw delivers critical engineering solutions for industrial assemblies requiring secure, semi-permanent fastening. Crafted from 18-8 stainless steel, it resists corrosion and maintains integrity in moist or chemically aggressive settings, reducing maintenance frequency. The Class 3A thread fit and coarse UNC threading ensure tight tolerances and rapid installation, preventing loosening from vibrations in motors, conveyor systems, and precision equipment. The headless design and oval tip distribute pressure evenly, safeguarding delicate shafts and gears from indentation. Ideal for securing collars, pulleys, and knobs, this hex drive set screw meets the rigorous demands of manufacturing, automation, and machinery sectors.
Specification Summary & Compliance
This set screw adheres to ASME B18.3 specifications, with Class 3A thread fit ensuring high precision and interchangeability. The UNC coarse thread (6-32 size) and right-hand direction provide reliable engagement, while the 1/2" length and 1/16" hex drive facilitate standard tool usage. It is fully RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, confirming the absence of hazardous substances for safe industrial use.
