Professional Applications & Engineering Value
This 1"-8 UNC hex head screw delivers critical performance advantages in demanding industrial settings. The 18-8 stainless steel composition provides inherent corrosion resistance, making it suitable for applications exposed to moisture, chemicals, and outdoor elements. The partially threaded design offers strategic advantages in structural connections where maximum grip length isn't required, reducing material usage while maintaining clamping force. With 80,000 PSI tensile strength and Rockwell B70 hardness, this fastener withstands high stress applications in machinery, construction, and heavy equipment. The external hex drive and coarse UNC threads enable rapid installation in production environments, while the Class 2A thread fit ensures consistent engagement without binding or loosening under vibration.
Specification Summary & Compliance
This heavy-duty hex head screw features precise Class 2A thread fit per UNC standards with 1"-8 coarse thread configuration and 3 1/4" overall length. Manufactured from 18-8 stainless steel with Rockwell B70 hardness and 80,000 PSI tensile strength. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, meeting the latest industry standards for hazardous substance restrictions and chemical safety.
