S-92865A928 1"-8 x 6" ASME B18.2.1, SAE J429 Medium-Strength Grade 5 Steel Hex Head Screws

Key Features & Benefits at a Glance

• Exceptional load-bearing capacity with 120,000 psi tensile strength for reliable performance in demanding applications
• Superior corrosion resistance provided by zinc plating, extending service life in harsh industrial environments
• Optimized thread engagement through Class 2A thread fit ensuring consistent clamping force and vibration resistance
• Enhanced durability from Rockwell C25 hardness maintaining structural integrity under repeated stress
• Efficient installation with external hex drive design allowing high-torque application using standard tools
• Versatile coarse threading (1"-8 UNC) facilitating quick assembly in various materials including steel and construction composites
• Full-length threading enabling maximum adjustability and uniform stress distribution along the entire 6" length

Professional Applications & Engineering Value

Engineered for heavy-duty industrial fastening, this Grade 5 hex head screw addresses critical challenges in machinery assembly, structural steel connections, and construction frameworks. The combination of high-strength steel material and zinc plating creates a robust barrier against environmental degradation while maintaining 120,000 psi tensile strength for load-critical joints. The 1"-8 UNC coarse thread configuration prevents cross-threading during high-speed assembly operations and provides superior pull-out resistance in softer substrates. With fully threaded design and external hex drive, installers achieve uniform clamping force across the entire 6" length, eliminating weak points in extended connections common in conveyor systems, equipment mounting, and structural bracing applications.

Specification Summary & Compliance

Manufactured to ASME B18.2.1 and SAE J429 Grade 5 specifications with Class 2A thread fit tolerance for precision engagement. The coarse thread spacing (8 TPI) conforms to UNC standards while the zinc plated finish meets RoHS 3 (2015/863/EU) compliance requirements. All dimensional characteristics including 1" thread diameter, 1 1/2" head width, and 43/64" head height maintain strict adherence to industrial fastener standards for interchangeable use across compliant applications.
