Key Features & Benefits at a Glance
- Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh industrial environments
- Maximum holding power and vibration resistance through the cup point design that bites into mating surfaces
- Precise, reliable fastening ensured by Class 3A thread fit for tight tolerances and secure assemblies
- Easy installation and high torque capability with the 1/4" hex drive, preventing tool slippage
- Exceptional durability and strength from Rockwell B80 hardness, resisting deformation under heavy loads
- Broad industry compatibility with UNC coarse threading and right-hand direction for common applications
- Regulatory peace of mind with compliance to ASME B18.3, RoHS 3, and REACH standards
Professional Applications & Engineering Value
This 1/2"-13 UNC set screw is engineered to solve critical challenges in industrial assembly, where vibration resistance and permanent positioning are paramount. The 18-8 stainless steel material offers excellent corrosion resistance, reducing maintenance in moist or chemically aggressive settings. Its cup point concentrates force to create a secure bite into shafts, gears, or collars, preventing slippage in high-torque applications like machinery drives and automotive components. The hex headless design allows for flush mounting in confined spaces, while the coarse UNC thread ensures quick installation and robust performance. Certified to ASME B18.3, it delivers consistent quality for engineers requiring reliable, long-term fastening solutions in manufacturing, aerospace, and heavy equipment.
Specification Summary & Compliance
This set screw adheres to precise dimensional standards, including Class 3A thread fit for superior accuracy and UNC coarse threading (1/2"-13) with right-hand direction. It is manufactured in compliance with ASME B18.3 specifications and meets regulatory requirements such as RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), ensuring environmental safety and material reliability for global industrial use.
