FAQS on din 933 10.9

Q: What is the difference between DIN 933 and DIN 931 bolts?

A: DIN 933 specifies partially threaded hex bolts, while DIN 931 defines fully threaded hex bolts. Both standards use metric measurements but differ in thread coverage length.

Q: What does 10.9 mean in DIN 933 10.9 bolts?

A: The 10.9 marking indicates a high-strength bolt with 1000 MPa minimum tensile strength and 0.9 ratio of yield-to-tensile strength. It's suitable for heavy-duty applications requiring high clamping force.

Q: What does M6x12 mean in DIN 933 specifications?

A: M6x12 denotes a metric bolt with 6mm diameter and 12mm length (measured from head bearing surface). This sizing follows DIN 933's dimensional standards for hex head bolts.

Q: Are DIN 931 and DIN 933 bolts interchangeable?

A: They share similar dimensions but aren't fully interchangeable. DIN 931's full-thread design works better for adjustable joints, while DIN 933's partial threading suits fixed clamped connections.

Q: What applications typically use DIN 933 10.9 bolts?

A: These high-strength bolts are commonly used in automotive systems, machinery assembly, and structural applications requiring vibration resistance and high tensile strength.
