S-92620A834 3/4"-10 x 1 3/4" ASME B18.2.1, SAE J429 High-Strength Grade 8 Steel Hex Head Screws

Key Features & Benefits at a Glance

• Exceptional tensile strength of 150,000 psi ensures reliable performance in the most demanding heavy-duty applications, reducing the risk of fastener failure.
• Superior corrosion resistance from the zinc yellow-chromate plating extends service life and maintains integrity in harsh industrial environments.
• High hardness (Rockwell C33) provides excellent wear resistance and durability, minimizing deformation under high stress.
• Coarse UNC threads allow for faster installation and better performance in materials where fine threads may strip or cross-thread.
• Full threading along the 1 3/4" length offers maximum grip and adjustability, ensuring a secure fit in various material thicknesses.
• External hex drive and hex head design enable easy installation and high torque application with standard tools, improving assembly efficiency.
• Compliance with ASME B18.2.1 and SAE J429 standards guarantees consistent quality, dimensional accuracy, and interchangeability for engineering projects.

Professional Applications & Engineering Value

This Grade 8 hex head screw is engineered to solve critical challenges in heavy machinery, construction, and automotive assemblies where high tensile strength and corrosion resistance are paramount. The steel material combined with zinc yellow-chromate plating provides a robust barrier against rust and chemical exposure, making it ideal for outdoor or corrosive environments. Its coarse UNC thread and Class 2A thread fit ensure quick, reliable fastening in soft materials or where vibration resistance is needed, reducing installation time and maintenance costs. Fully threaded for versatile grip, this industrial hex screw delivers consistent clamping force, preventing loosening in dynamic loads and enhancing structural integrity across applications like equipment frames, engine components, and structural steel connections.

Specification Summary & Compliance
