Professional Applications & Engineering Value

This 400 Nickel set screw delivers exceptional performance in industrial applications where corrosion resistance and reliable positioning are critical. The headless hex drive design with 1/8" drive size allows installation in confined spaces while maintaining tool engagement. The cup point tip creates permanent indentation in shaft components, preventing rotational slippage in high-vibration environments like motors, gears, and precision machinery. Manufactured to Class 3A thread fit with 1/4"-20 UNC coarse threads, this fastener ensures precise alignment and reduces installation time compared to fine-thread alternatives. The combination of 400 Nickel material and rigorous manufacturing standards makes these set screws ideal for aerospace, marine, and chemical processing equipment where durability and regulatory compliance are paramount.

Specification Summary & Compliance
