Professional Applications & Engineering Value
This 316 stainless steel set screw delivers exceptional performance in demanding industrial environments where corrosion resistance and vibration resistance are critical. The Class 3A thread fit provides tighter tolerances than standard fasteners, ensuring precise alignment and reduced loosening in machinery, automotive, and aerospace applications. The headless design with hex drive allows for flush mounting in confined spaces while maintaining high torque capability. The UNF fine threading offers superior holding power in softer materials and thin-walled applications, while the cup tip creates positive mechanical locking against shaft surfaces. Engineered to ASME B18.3 standards, this set screw provides reliable fastening solutions for precision equipment, rotating assemblies, and permanent installations where maintenance access is limited.
Specification Summary & Compliance
This precision fastener features 1/4"-28 UNF fine threading with Class 3A thread fit for superior dimensional accuracy and engagement. The 5/8" length and headless hex drive design comply with ASME B18.3 specifications for set screws. Manufacturing and material compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring suitability for global industrial applications requiring restricted substance compliance.
