S-92198A935 1"-8 x 11" ASME B18.2.1 18-8 Stainless Steel Hex Head Screws

Key Features & Benefits at a Glance

• Exceptional tensile strength of 80,000 PSI ensures reliable performance in high-stress industrial applications, reducing the risk of fastener failure.
• Superior corrosion resistance from 18-8 Stainless Steel construction extends service life in harsh environments, minimizing maintenance and replacement costs.
• Coarse UNC threading with Class 2A fit provides easier, faster assembly and better resistance to vibration loosening compared to fine threads.
• Heavy-duty hex head design with external drive allows for high torque application using standard tools, ensuring secure fastening in demanding conditions.
• Partial threading with 2½" minimum thread length offers optimal grip strength while leaving an unthreaded shank for enhanced shear resistance.
• Rockwell B70 hardness maintains thread integrity and prevents deformation during installation and throughout the product lifecycle.
• Full regulatory compliance with ASME B18.2.1, RoHS 3, and REACH ensures material safety and meets international industrial standards.

Professional Applications & Engineering Value

This heavy-duty hex head screw delivers critical engineering solutions where corrosion resistance and structural integrity are paramount. The 18-8 stainless steel composition prevents rust and degradation in demanding environments including marine applications, chemical processing equipment, and outdoor infrastructure. The 1"-8 UNC coarse thread configuration enables rapid installation in thick materials while maintaining superior resistance to vibration-induced loosening. With partial threading and substantial 11" length, this fastener provides optimal clamping force distribution while the unthreaded shank section enhances shear strength. The external hex drive accommodates high-torque applications common in structural steel connections, heavy machinery assembly, and industrial framing systems where reliability cannot be compromised.

Specification Summary & Compliance

Manufactured to precise dimensional standards with Class 2A thread fit per UNC specifications, ensuring consistent performance and interchangeability. The coarse thread spacing and right-hand thread direction follow industry-standard configurations for compatibility with existing components. This product meets ASME B18.2.1 manufacturing specifications for hex head screws and demonstrates compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, confirming the absence of restricted hazardous substances for industrial use worldwide.
