Our 10.9 Grade Hex Socket Countersunk Head Screws, compliant with DIN7991 standard, are high-strength fasteners engineered for heavy-duty industrial, mechanical, and construction applications. Crafted from premium high-strength carbon steel, these bolts deliver exceptional tensile and shear strength, making them ideal for scenarios that require reliable, long-lasting fixation under high loads and harsh working conditions.
Featuring a professional blue and white zinc plating finish, the screws offer superior corrosion resistance, rust protection, and wear resistance—effectively extending their service life in indoor, outdoor, and industrial environments. The zinc coating also provides a smooth, clean appearance, ensuring compatibility with various equipment and structural finishes.
Designed with a countersunk head and hex socket drive, these machine screws sit flush with the surface of the mounted material after installation, eliminating protrusions that could interfere with equipment operation or safety. The hex socket design allows for easy, precise installation and removal with standard hex tools, improving efficiency in assembly, maintenance, and repair work.
Compliant with the DIN7991 standard, these screws feature precision-machined threads that ensure tight, secure engagement with matching nuts or mounting holes, preventing loosening even under vibration or heavy use. They are widely applicable to industrial machinery, construction structures, mechanical equipment, automotive components, and heavy-duty fixtures—meeting the high standards of professional industrial and commercial use.
Each screw undergoes strict quality inspection to ensure consistent dimensions, accurate threading, and adherence to 10.9 grade strength standards. Whether for large-scale industrial projects, mechanical assembly, or heavy-duty fixing, these high-strength carbon steel countersunk hex socket bolts deliver durability, reliability, and performance you can trust.
