Frequently Asked Questions
Does the product truly and fully comply with the DIN 3570 standard?
We provide compliance test reports issued by independent laboratories with shipments to certify that dimensions, tolerances, and mechanical properties fully meet the standard.
Are the Material Test Certificates (MTC/MTR) complete?
Yes. Each batch of shipped products is accompanied by traceable Material Test Reports (MTR), confirming compliance with ASTM A193 B8 or B8M specifications.
Are the threads of the bolt fully threaded or partially threaded? What are the standard dimensions for length and inner width (R)?
According to DIN 3570 standard, the M8 square U-bolt typically features a
partial threading design, with threads machined to specific lengths close to the bend. We provide detailed dimensional drawings for confirmation based on your installation requirements.
Can samples be provided, and how are they charged?
Samples (1-5 sets) are provided free of charge with customer-covered shipping costs. Sample costs are deducted from your first formal order.
How does the product perform in terms of stress corrosion cracking (SCC) resistance under long-term vibration or humid environments?
A193 B8M (316 material), with its molybdenum content, offers significantly better resistance to chloride-induced stress corrosion cracking (SCC) compared to B8 (304 material).
Recommended for high-corrosion, high-stress environments like marine and chemical industries.
