Chenango Supply 5/8-11 x 5 Grade 8 Hex Head Cap Screws, Alloy Steel Hex Bolts, 150,000 PSI Tensile Strength, Yellow Zinc Chromate Finish, USS Coarse Thread Heavy Duty Fasteners, 10 Pcs (5/8-11 x 5)

Grade 8 alloy steel 5/8-11 x 5"" hex head cap screws engineered for heavy machinery, automotive repair, agricultural equipment, and industrial fastening applications where maximum tensile strength and extended bolt length are required. Specifications Material: Alloy steel, quenched and tempered Grade: SAE J429 Grade 8 Tensile strength: 150,000 PSI minimum Hardness: Rockwell C33-39 Thread: 5/8-11 USS coarse thread Size: 5/8-11 x 5 inches Finish: Yellow chromate zinc Quantity: 10 pieces Performance & Application Explanation These hex head cap screws are manufactured from quenched and tempered alloy steel to Grade 8 specifications, delivering the highest strength rating available in standard SAE fasteners. The 5 inch length provides maximum reach for through-bolting heavy equipment frames, thick structural assemblies, and stacked components where deep fastener penetration is required. The 5/8-11 USS coarse thread form provides strong engagement with matching nuts and tapped holes, supporting secure assembly in high-vibration and high-load environments. Yellow chromate zinc coating offers corrosion protection while maintaining visibility for inspection and torque verification. B2B Use Cases Applicable for heavy equipment frames, truck and trailer assemblies, agricultural machinery, construction equipment, fabrication shops, structural connections, industrial mounting applications, and fastening tasks requiring Grade 8 strength ratings with maximum bolt length. Quality & Trust Reassurance Thread sizing and material hardness align with SAE J429 Grade 8 standards for accuracy and durability. Designed for mechanics, maintenance crews, and fabricators seeking reliable high-strength fasteners for demanding applications where joint failure is not acceptable.

• GRADE 8 ALLOY STEEL CONSTRUCTION – Quenched and tempered alloy steel delivers 150,000 PSI minimum tensile strength for heavy-duty applications where standard fasteners fail, meeting SAE J429 Grade 8 specifications for critical load-bearing joints.
• 5/8-11 x 5" SIZE SPECIFICATION – Maximum 5 inch length accommodates deep material stacks, heavy equipment frames, and structural assemblies where extended bolt reach is required for secure through-bolting of thick components.
• 5/8-11 USS COARSE THREAD – Standard coarse thread provides reliable engagement and faster assembly in heavy machinery, automotive, agricultural equipment, and structural applications requiring secure fastening under high stress.
• YELLOW CHROMATE ZINC COATING – Corrosion-resistant finish protects against moisture and environmental exposure, extending service life in outdoor, industrial, and equipment repair environments where rust compromises joint integrity.
• 10-PIECE PACK FOR MAINTENANCE AND REPAIR – Quantity supports equipment repair, fabrication projects, fleet maintenance, and MRO operations requiring high-strength hex head cap screws for demanding fastening tasks.
