Frequently Asked Questions (FAQ)
What is the difference between an M6x1.0 and an M6x0.75 thread?
The M6x1.0 is the standard coarse thread pitch, offering faster assembly and better tolerance to debris. The M6x0.75 is a fine thread pitch, providing slightly higher tensile strength and improved adjustment precision. The coarse thread (1.0mm) is the most common and recommended for general industrial use.
Can you provide hex M6 bolts with certification?
Yes. We can supply full material certification (3.1 Mill Test Certificates) for our bolts, detailing chemical composition and mechanical properties. This is standard for higher-grade bolts (e.g., 10.9, 12.9, A4-80) and available for all products upon request.
What finish is best for outdoor or marine environments?
For severe outdoor or saltwater (marine) environments, we strongly recommend A4-316 stainless steel hex M6 bolts or carbon steel bolts with a high-performance coating like hot-dip galvanizing (HDG) or Geomet®. A4 stainless offers the best all-around corrosion resistance.
Do you offer custom lengths or head markings?
Absolutely. We specialize in custom manufacturing. We can produce M6 hex head bolts in non-standard lengths, with specific head markings (property class), and unique packaging or kitting to suit your automated assembly processes.
What are the packaging options for bulk orders?
Standard bulk packaging includes sturdy cardboard boxes or master cartons with inner plastic bags. We can also accommodate special requests such as bulk sacks, labeled poly bags, or custom-sized boxes to integrate directly into your production line.
