Professional Applications & Engineering Value
This 316 stainless steel headless set screw is engineered to solve critical fastening challenges in demanding environments. Its corrosion-resistant material prevents degradation from chemicals, moisture, and salt exposure, making it perfect for marine, chemical processing, and food industry equipment. The Class 3A thread fit and coarse UNC thread provide superior resistance to loosening under vibration, essential for machinery, motors, and precision instruments. The headless design with a hex drive allows flush mounting in tight spaces, while the 118° cone point bites securely into shafts and collars, ensuring components stay aligned and fixed. Ideal for permanent or semi-permanent assemblies where reliability and space constraints are paramount.
Specification Summary & Compliance
This set screw features a 6-32 UNC coarse thread with a Class 3A precision fit for tight tolerances and reliable engagement. Dimensions include a 1/8" length and 1/16" hex drive. It is manufactured in compliance with ASME B18.3 standards and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safety and sustainability for industrial use.
