FAQ

What is the difference between Grade 8.8 and 10.9 for an 8mm hex bolt?

The grade indicates the tensile strength of the bolt. A Grade 10.9 bolt has a higher tensile and yield strength than an 8.8 grade, making it suitable for higher-stress applications. The choice depends on the design load and safety factor requirements of your specific assembly.

Can I get these bolts with a certification?

Yes. We can provide full material certification, including 3.1 Mill Test Certificates compliant with EN 10204, for all our high-strength bolts, including the 8mm hex bolt. Please specify this requirement when requesting a quote.

Do you offer custom lengths or special finishes?

Absolutely. While we stock standard lengths, we regularly fulfill orders for custom lengths and specialized anti-corrosion finishes like dacromet or black oxide. Contact our sales team with your specifications for a custom quotation.

What is the standard packaging for bulk orders?

For industrial B2B orders, we typically pack in sturdy, labeled cartons or boxes, with inner plastic bags for corrosion protection. Bulk palletized options are also available. We aim to provide packaging that ensures product integrity during transit and simplifies handling at your facility.

How do I determine the correct length of 8mm hex bolt needed?

The general rule is that the bolt should be long enough so that the full thread protrudes past the nut after tightening. A simple calculation is: Bolt Length = Material Thickness + Washer Thickness + Nut Height + (Approx. 1.5 x Diameter for thread protrusion). Our technical team can assist with specific calculations.
