FAQS on din 933 m20

Q: What is the difference between DIN 933 M20 and DIN 931?

A: DIN 933 M20 refers to a fully threaded hexagon head bolt with 20mm diameter, while DIN 931 specifies partially threaded bolts. Both follow German industrial standards but differ in thread coverage and application scenarios.

Q: What material grades are available for M20 DIN 933 bolts?

A: M20 DIN 933 bolts are typically available in carbon steel (4.8/8.8/10.9 grades), stainless steel (A2/A4), and alloy steel. Material selection depends on required tensile strength and corrosion resistance.

Q: How long is the thread portion on DIN 933 M20 bolts?

A: DIN 933 M20 bolts feature full-length threading from head to tip. The complete thread length distinguishes them from DIN 931 bolts which have partially threaded designs.

Q: What wrench size fits DIN 933 M20 hex head bolts?

A: The standard hex head for DIN 933 M20 requires a 30mm wrench. This corresponds to the ISO 4017 dimensional specifications for M20 metric bolts.

Q: Can DIN 933 DIN 931 bolts be used interchangeably?

A: No, DIN 933 (full thread) and DIN 931 (partial thread) serve different purposes. Full-thread bolts provide better load distribution, while partial-thread offers stronger shear resistance in specific applications.
