FAQ

What is the difference between a Grade 8.8 and a Grade 10.9 15mm hex bolt?

Grade 8.8 is a medium-strength bolt with a tensile strength of 800 MPa and a yield strength of 640 MPa. Grade 10.9 is a high-strength bolt with a tensile strength of 1000 MPa and a yield strength of 900 MPa. The choice depends on the design load and safety factor required for your application.

Can you supply 15mm hex bolts with specific certifications?

Yes. We regularly produce bolts with test certificates (3.1 Material Certificates as per EN 10204) and can comply with specific project certifications required for infrastructure, energy, or government contracts.

What is the lead time for a standard container load of 15mm hex bolts?

For standard grades and finishes, we typically maintain stock for prompt dispatch. Full container load (FCL) production and shipping lead times are generally 4-6 weeks. We provide precise timelines with every quotation.

How should I specify my 15mm hex bolt requirement?

For an accurate quote, please specify: Diameter (15mm), Thread Pitch, Length (under head), Property Class/Grade, Finish/Coating, Quantity, and any applicable Standard (e.g., DIN, ISO, ASTM).

Do you offer samples for testing and approval?

Absolutely. We encourage and support product validation. We can provide sample 15mm hex bolts for your engineering or quality team to test and approve before proceeding with a bulk order.
