Fractional Size Grade 5 Zinc Cr3 Clear Plate Bolt
Fractional Size Grade 5 Hex Head Cap Screws with Clear Cr3 Zinc Plating
Fractional Size Grade 5 Hex Head Cap Screws with Clear Cr3 zinc plating are engineered to deliver high-strength fastening performance with added corrosion resistance. Designed for demanding industrial environments, these fasteners provide reliable clamping force, precise torque control, and long service life in mechanical, structural, and equipment assembly applications.
High-Strength, Heat-Treated Construction
Manufactured from heat-treated medium carbon steel, Grade 5 hex head cap screws are built to withstand higher stress and vibration than lower-grade fasteners. With a minimum tensile strength of 120,000 psi and a yield strength of 92,000 psi, they are well suited for automotive systems, machinery, agricultural equipment, and construction assemblies where durability and resistance to shear are essential. Their strength profile ensures consistent performance under repeated loading and challenging operating conditions.
Clear Cr3 Zinc Plating for Corrosion Protection
The Clear Cr3 zinc plating adds a thin, uniform protective layer that guards against rust and oxidation in mildly corrosive environments. This trivalent chromium (Cr3) finish is an environmentally responsible alternative to traditional hexavalent chromium coatings, offering improved compliance with modern environmental standards. In addition to corrosion resistance, the clear zinc finish provides a clean, bright appearance that enhances the overall look of finished assemblies.
Fractional Sizing and Industry Standards
Available in standard fractional (inch) sizes, these Grade 5 hex head cap screws are fully compatible with U.S. hardware systems. They conform to ASME B18.2.1 dimensional requirements and meet SAE J429 mechanical property specifications. Precision-rolled threads ensure smooth installation, consistent load distribution, and reliable engagement with standard hex nuts and washers.
