FAQ
What is the difference between Grade 8.8 and 10.9 for a 13mm hex bolt?
Grade indicates the bolt's strength class. A Grade 10.9 bolt has a higher tensile and yield strength than an 8.8, making it suitable for more demanding, high-stress applications. The choice depends on your specific load and safety factor requirements.
Can I get these bolts with a certification or test report?
Yes. We can provide Material Test Reports (MTRs) or 3.1 certification for our 13mm hex bolts upon request, detailing chemical composition and mechanical properties for quality-critical projects.
What finish is best for outdoor or marine environments?
For severe outdoor or marine exposure, we recommend hot-dip galvanized (HDG) bolts. This finish provides a thick, durable zinc barrier that offers the best long-term protection against corrosion.
Do you offer custom lengths or markings?
Absolutely. We specialize in providing tailored solutions. Custom lengths, non-standard threads, and head markings (like grade indicators) can be manufactured to meet your exact specifications for OEM applications.
What is the standard packaging for bulk orders?
Standard bulk packaging is in sturdy, sealed cartons or boxes, with inner plastic bags for corrosion protection. We also offer palletized and shrink-wrapped options for large-volume shipments to ensure secure and efficient logistics.
