Fractional Sizes Grade 8 Yellow Zinc Bake Cr6 Plate Bolt
Fractional Size Grade 8 Hex Head Cap Screw with Yellow Cr6 Zinc Plating
The Fractional Size Grade 8 Hex Head Cap Screw with Yellow Cr6 Zinc Plating is engineered for superior strength, corrosion resistance, and long-term durability in the toughest industrial environments. Manufactured from medium carbon alloy steel and heat-treated to meet SAE J429 Grade 8 and ASTM A354 Grade BD specifications, this premium fastener delivers an outstanding tensile strength of approximately 150,000 PSI, making it ideal for heavy-duty applications that demand both power and precision.
The yellow zinc Cr6 plating provides a dual benefit: enhanced corrosion protection and a distinctive gold-colored finish that allows for easy visual identification of high-strength hardware. The hexagonal head design ensures excellent torque transmission and secure tightening, while the plated surface provides added resistance against rust, oxidation, and environmental wear — significantly extending service life, especially in automotive, construction, agricultural, and machinery assembly applications.
These Grade 8 cap screws are designed for use in high-stress environments where superior performance is required, such as engine mounting, equipment fabrication, and structural bolting. The yellow Cr6 zinc coating also improves lubricity during installation, helping to achieve accurate torque values and reducing the risk of thread galling.
Available in fractional Fractional sizes ranging from 1/4" through 1-1/2", these screws are precision-threaded in both UNC and UNF series to ensure compatibility with matching Grade 8 nuts and hardened flat washers. Each screw undergoes rigorous inspection to maintain tight dimensional tolerances and consistent quality.
For projects that demand maximum strength, corrosion resistance, and professional-grade reliability, the Fractional Size Grade 8 Hex Head Cap Screw with Yellow Cr6 Zinc Plating is the trusted solution — combining American manufacturing excellence with unmatched mechanical performance.
