Finished Hex Nuts – Fractional Sizes, Grade 5 Clear Cr3 Zinc Plating

Strength, Corrosion Resistance, and Reliable Performance

Finished hex nuts in fractional sizes with Grade 5 strength and clear Cr3 zinc plating are a dependable fastening solution for a wide range of industrial, automotive, and construction applications. Designed to pair with Grade 5 bolts, these hex nuts provide higher strength than Grade 2 hardware while maintaining excellent versatility for general-purpose and medium-duty assemblies.

Manufactured from medium carbon steel and heat treated to meet Grade 5 requirements, these finished hex nuts deliver consistent performance in applications where strength, vibration resistance, and secure clamping force are critical.

Fractional Sizes and Applications

Versatile Sizing for Standard U.S. Fasteners

Grade 5 finished hex nuts are available in common fractional sizes to match standard SAE bolts and threaded rods. Typical size ranges include:

1/4"
5/16"
3/8"
7/16"
1/2"
5/8"
3/4"
1"

Fractional sizing ensures compatibility with U.S. standard fasteners commonly used in machinery, structural assemblies, equipment manufacturing, and automotive repair.

Grade 5 Construction and Cr3 Zinc Plating

Balanced Strength with Corrosion Protection

Grade 5 hex nuts are heat treated to achieve higher tensile and proof load ratings than low-carbon fasteners, making them suitable for moderate to high-stress applications.

Clear Cr3 (trivalent chromium) zinc plating adds a protective barrier against rust and corrosion while maintaining an environmentally friendly finish that complies with modern RoHS and REACH standards. The clear zinc appearance provides a clean, professional look and smooth thread engagement.

Material: Medium carbon steel
Grade: SAE Grade 5
