USA Manufactured Fractional Size Hex Head Cap Screw with Clear Zinc Cr3 Plate
USA Manufactured Grade 5 Hex Head Cap Screws with Clear Zinc Cr3 Plating
USA manufactured Grade 5 hex head cap screws with clear zinc Cr3 plating are premium fasteners engineered for strength, corrosion resistance, and long-term reliability. Designed for demanding industrial, automotive, and construction applications, these fractional-size fasteners deliver consistent performance where secure, high-strength fastening is critical.
High-Strength Material and Heat-Treated Performance
Grade 5 hex head cap screws are manufactured from heat-treated medium carbon steel, commonly AISI 1045 or equivalent. This material and process provide a minimum tensile strength of 120,000 psi and a yield strength of 92,000 psi, making these fasteners ideal for medium- to heavy-duty applications. Their strength allows them to withstand vibration, shear forces, and repeated loading in machinery, equipment frames, and structural assemblies.
Clear Zinc Cr3 Plating for Corrosion Protection
The clear zinc trivalent chromium (Cr3) plating adds a protective barrier against rust and oxidation while maintaining the fastener’s mechanical integrity. This modern coating offers improved corrosion resistance compared to traditional hexavalent chromium finishes and is RoHS compliant, making it a safer and more environmentally responsible choice. The bright silver appearance also enhances the visual quality of finished assemblies.
Precision Design and Fractional Sizing
These hex head cap screws feature a six-sided head that supports high torque installation using standard wrenches or sockets. Unified National Coarse (UNC) threads provide smooth installation and secure thread engagement. Available in fractional sizes ranging from 1/4" to 1" in diameter and 1/2" to 6" in length, these fasteners ensure compatibility with U.S. standard hardware systems and a wide range of applications.
Industry Standards and Quality Assurance
USA-made Grade 5 hex head cap screws meet or exceed ASME B18.2.1 dimensional requirements and SAE J429 mechanical specifications. This ensures consistent thread tolerances, accurate dimensions, and dependable performance in every installation.
