Regular stress-strain analysis and torsion tests verify that the actual load capacity meets or exceeds grade specs.
Full traceability provided via Mill Test Reports (MTR) for every shipment, complying with ASTM and DIN.
Through bolts provide superior clamping force as they pass completely through the joined materials and are secured with a nut, ensuring a more stable and high-load connection.
Grade 10.9 or 12.9 are recommended due to their higher tensile strength and fatigue resistance, preventing bolt failure under continuous stress.
We utilize SS316 stainless steel or Hot-Dip Galvanization, followed by a passivating process to create a protective oxide layer on the surface.
Yes, we offer fully customizable lengths based on your technical drawings, with precise thread cutting and head shaping to meet OEM specifications.
Depending on the volume and material, large orders typically ship within 15-30 days. We maintain a raw material buffer to accelerate production.
Yes, every shipment is accompanied by a Mill Test Certificate confirming the chemical composition and mechanical properties of the steel used.
