ASME B18.9 No.7 Head Plow Bolts | Round Countersunk | Reverse Key | A307, F468, F593, SAE J429

Description

ASME B18.9 No.7 Head Plow Bolts (Round, Countersunk, Reverse Key) are robust, high-strength fasteners used in demanding applications such as heavy machinery, agriculture equipment, and construction structures. The round countersunk head ensures a smooth surface after installation, while the reverse key design prevents rotation during tightening—ideal for high-vibration environments.

These bolts comply with Table 2 of the ASME B18.9 standard and are available in multiple specifications such as ASTM A307, F468, F593, and SAE J429, ensuring compatibility with various mechanical and corrosion-resistant applications. Manufactured from carbon steel or stainless steel, and offered in grades 4.8, 8.8, 10.9, and 12.9, they meet a wide range of structural and industrial requirements.

Surface finishes include plain, black oxide, zinc electroplating, hot dip galvanizing, copper plating, nickel plating, and zinc impregnation, tailored to provide corrosion resistance and durability in tough environments.
