Bulk 7/8"-9 L9 Hex Head Cap Screws - Durable and Reliable

Our Bulk 7/8"-9 L9 Hex Head Cap Screws are designed for the most demanding applications, offering unmatched strength and resilience. Crafted in the USA from high-grade alloy steel, these fasteners feature a coarse thread (UNC) for optimal grip and ease of assembly. With a tensile strength of 180,000 PSI, these L9 screws are perfect for bulk orders, providing durability and efficiency in high-stress projects. Key features include increased head height, radius under head for stress resistance, and a smooth bearing surface for even load distribution.

• Increased Head Height: Ensures better wrench engagement and reduced risk of slippage.
• Radius Under Head: Fortifies stress resistance, enhancing durability under extreme loads.

Superior Mechanical Properties and Corrosion-Resistant Finish

These L9 Hex Head Cap Screws boast exceptional mechanical properties, with a hardness of 38 to 42 HRC and a surface hardness of HR15N 81.5 Max. The tensile strength is a minimum of 180,000 PSI, while the yield strength is at least 155,000 PSI. They are also corrosion-resistant, thanks to a zinc yellow CR+3 plating that complies with ASTM F1941/F1941M Fe/Zn 5CN standards and provides 96 hours of salt spray protection. Additional features include a proof load strength of 145,000 PSI and an elongation of 12% minimum.

• Hardness: 38 to 42 HRC
• Surface Hardness: HR15N 81.5 Max
