Fractional Sizes Grade 8 Yellow Zinc Bake Cr6 Plate Bolt
Fractional Size Grade 8 Hex Head Cap Screws with Yellow Cr6 Zinc Plating
Fractional Size Grade 8 Hex Head Cap Screws with Yellow Cr6 zinc plating are engineered for maximum strength, corrosion resistance, and long-term durability in extreme-duty applications. Designed for high-stress industrial environments, these premium fasteners provide the strength and reliability required for critical mechanical and structural assemblies.
Maximum Strength with Heat-Treated Alloy Steel
Manufactured from heat-treated medium carbon alloy steel, Grade 8 hex head cap screws meet SAE J429 Grade 8 and ASTM A354 Grade BD specifications. With a minimum tensile strength of approximately 150,000 psi, these fasteners deliver exceptional clamping force and resistance to shear, fatigue, and vibration. This makes them ideal for heavy-duty applications such as automotive powertrain systems, construction equipment, agricultural machinery, and structural bolting where failure is not an option.
Yellow Cr6 Zinc Plating for Enhanced Corrosion Protection
The Yellow Cr6 zinc plating provides a durable protective coating that shields the fastener from rust, oxidation, and environmental wear. This finish offers increased corrosion resistance compared to standard clear zinc coatings and is well suited for outdoor, humid, and industrial environments. The distinctive gold-colored appearance allows for quick visual identification of Grade 8 hardware during installation and maintenance. Additionally, the plated surface improves lubricity, helping achieve accurate torque values while reducing the risk of thread galling.
Precision Design and Fractional Sizing
Grade 8 hex head cap screws feature a six-sided head for superior torque transfer and secure tightening. Available in standard fractional (inch) sizes ranging from 1/4" through 1-1/2", these fasteners are offered in both UNC and UNF thread series for versatility across a wide range of applications. When paired with Grade 8 hex nuts and hardened flat washers, they create robust, load-bearing connections capable of withstanding extreme conditions.
