FAQ

What is the difference between an M6 hex bolt grade 8.8 and 10.9?

The grade indicates the bolt's strength class. A grade 10.9 M6 hex bolt has a higher tensile and yield strength than an 8.8 grade, making it suitable for more critical, high-stress applications. The choice depends on the design requirements of your joint.

Can I get M6 hex bolts in stainless steel for outdoor use?

Absolutely. We recommend A2 (304) stainless steel for general outdoor use and A4 (316) stainless steel for highly corrosive environments, such as coastal or chemical exposure areas. Both offer excellent corrosion resistance.

What length of M6 bolt should I order?

The ideal length allows for full thread engagement in the nut or tapped hole, plus a small protrusion. A general rule is that the bolt length should be at least 1.5 times the diameter of the bolt (9mm for M6) beyond the nut. Our technical team can assist with specific calculations.

Do you offer custom packaging or labeling?

Yes. We provide standard industrial packaging (boxes, cartons, drums) and can accommodate custom packaging, barcoding, and labeling to meet your kitting, assembly line, or inventory management needs.

What are your minimum order quantities (MOQs)?

We offer flexible MOQs to suit different customer needs, from sample quantities for testing to large bulk orders. Please contact our sales team for specific details based on your material and finish selection.
