Professional Applications & Engineering Value
This 8-36 UNF set screw delivers critical engineering solutions for precision assembly applications where space constraints and vibration resistance are paramount. The Black-Oxide Alloy Steel construction provides enhanced corrosion protection while maintaining the Rockwell C45 hardness necessary for repeated adjustments. The Class 3A thread fit ensures minimal backlash in precision machinery, automotive components, and electronic enclosures where fine thread fasteners prevent spontaneous loosening. The cup point tip creates permanent seating marks on shafts and collars, making this headless hex drive fastener ideal for permanent positioning applications in manufacturing equipment, robotics, and precision instruments where reliability cannot be compromised.
Specification Summary & Compliance
This precision set screw features 8-36 UNF fine threads with Class 3A thread fit tolerance for superior engagement. Manufacturing complies with ASME B18.3 specifications where identified under ASTM F912. The product maintains full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across global markets. Critical dimensions include 0.164" thread diameter, 1/8" length, and 5/64" hex drive size, all manufactured to industrial precision standards for consistent performance in professional applications.
