Applications
Our BOLTS and Nuts are designed for demanding applications across various industries including automotive, machinery, structural engineering, and infrastructure projects. The Grade 12.9 material with 800 MPa tensile strength makes them suitable for high-stress mechanical assemblies where safety and structural integrity are paramount.
For environments requiring corrosion resistance, ASTM F593 stainless steel bolts with F594 nuts provide excellent protection. ASTM A320 L7M low temperature bolting ensures reliable performance in cold climates and cryogenic environments, making them ideal for oil and gas, chemical plants, and power generation facilities.
Customization Options
We offer comprehensive customization services tailored to your specific requirements. Our fasteners feature fine thread type and durable hex head design for precise fitting and high torque application. Manufactured to DIN 912 socket head cap screws class 12.9 standards, we provide options with grade 12.9 material (σb ≥ 410 MPa), ASTM A320 L7 low temperature alloy steel bolts, and ASTM F593 stainless steel bolts with F594 nuts.
Weight varies by size, allowing selection of appropriate fasteners to match your project needs while ensuring optimal performance and compliance with industry standards.
