Professional Applications & Engineering Value
This 1/4"-20 UNC slotted headless set screw delivers critical engineering solutions for industrial applications requiring precise component fixation. The 18-8 stainless steel material provides excellent corrosion resistance, making it suitable for machinery, automotive, and outdoor equipment exposed to moisture and chemicals. Its cup tip design concentrates pressure on a small contact area, preventing shaft damage while maintaining strong grip under rotational forces. The coarse UNC threads and Class 2A thread fit ensure rapid installation and reliable performance in high-vibration environments. These headless set screws are particularly valuable in space-constrained assemblies where protruding fasteners are impractical, offering flush mounting while maintaining maximum holding power through their Rockwell B80 hardness.
Specification Summary & Compliance
This set screw features precise 1/4"-20 UNC coarse threads with Class 2A thread fit for consistent engagement and reliable performance. Manufacturing complies with ASME B18.6.2 specifications ensuring dimensional accuracy and mechanical properties. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, containing no restricted substances. With a length of 3/8" and cup tip configuration, this fastener meets industrial standards for quality and safety in demanding applications.
