Professional Applications & Engineering Value

This 6-32 UNC set screw is engineered to solve critical fastening challenges in demanding industrial settings. Its 316 stainless steel material provides superior resistance to corrosion from chemicals, saltwater, and extreme temperatures, making it ideal for marine, chemical processing, and outdoor equipment. The cup point tip creates a strong bite into shafts and collars, preventing slippage and maintaining positional integrity under high vibration and rotational forces. Combined with a Class 2A thread fit and coarse thread spacing, it ensures quick assembly and a secure hold in soft metals or plastics. The headless, slotted design allows for flush mounting in confined spaces, offering a reliable solution for securing gears, pulleys, and knobs where precision and durability are paramount.

Specification Summary & Compliance

This set screw features a 6-32 UNC thread with a Class 2A thread fit for precise dimensional accuracy. It is manufactured in compliance with the ASME B18.3 standard and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring it is free from hazardous substances and suitable for global industrial use.
