Key Features & Benefits at a Glance
- Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh industrial environments
- Maximum holding power achieved through cup point tip design that bites into materials for secure fastening
- Precise thread engagement with Class 3A fit ensuring tight tolerances and reliable performance
- Enhanced durability from Rockwell B80 hardness providing excellent wear resistance
- Easy installation in confined spaces thanks to headless hex drive design requiring minimal clearance
- Reliable coarse threading (UNC) that resists loosening under vibration and dynamic loads
- Industry-standard compliance meeting ASME B18.3 specifications for guaranteed quality
Professional Applications & Engineering Value
This 5-40 UNC set screw delivers exceptional engineering value in demanding applications where vibration resistance and permanent positioning are critical. The 18-8 stainless steel construction provides excellent corrosion resistance for outdoor equipment, marine components, and food processing machinery. The hex headless design allows installation in tight spaces where traditional screw heads won't fit, while the cup point tip creates permanent dimples in shafts and collars to prevent rotational slippage. With its Class 3A thread fit and coarse thread spacing, this right-hand thread set screw maintains secure fastening even under substantial vibration, making it ideal for precision machinery, automotive components, and industrial equipment requiring reliable shaft positioning.
Specification Summary & Compliance
This set screw features precise 5-40 UNC coarse threading with Class 3A thread fit for superior tolerance control. The 1/8" diameter and 1" length provide standardized dimensions compatible with industry requirements. Manufactured to ASME B18.3 specifications ensuring dimensional accuracy and performance reliability. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, making it suitable for global industrial applications with strict material restrictions.
