M10-1.5x65mm Flange Bolt and Nut Kit 4set- Grade 10.9 Alloy Steel, Black Zinc,Partially Thread, Serrated Self-Locking, Vibration Resistant for Automotive, Machinery & Heavy Duty

• Complete 4-Piece Flange Bolt Set with Storage Case：Get everything you need in one organized package! This kit includes 4 M10-1.5x65mm flange bolts and 4 matching flange nuts. The reusable transparent plastic case keeps all components securely stored, protected from moisture and dust, while making storage and portability effortless.
• Unlike ordinary black oxide (superficial, peel-prone, short rust resistance), our bolts feature electrochemical black zinc plating—forming a dense zinc film for superior rust/corrosion resistance, firm adhesion, salt spray/oxidation resistance—no flaking, far better durability. Engineered with Grade 10.9 High-Strength Alloy Steel: These flange bolts & nuts boast superior tensile strength and long durability, with upgraded black zinc plating for scratch resistance and longer service life.
• Vibration-Resistant Design & Easy Installation：The serrated flange acts as a self-locking mechanism, providing excellent resistance to loosening under extreme vibration and dynamic loads. Standard M10-1.5 machine threads with partially-length threading ensure deep, secure engagement. The hex head design allows for high-torque installation using common wrenches or socket tools.
• Versatile Across Demanding Industries and DIY Projects：A must-have for professional workshops and serious DIYers! Perfect for automotive repairs, machinery assembly, construction projects, equipment manufacturing, and structural frameworks—wherever high strength and vibration resistance are essential.
• Exceptional Value and Reliable Quality： This bulk package offers significant savings and convenience compared to purchasing hardware individually. We are committed to providing durable and reliable industrial-grade fasteners. Your satisfaction is our priority, and we stand behind the quality of our products.
