Technical Superiority: DIN 931 vs DIN 933 Decoded

Why do DIN 976 threaded rods pair perfectly with hex bolts? Our DIN 975-compliant stock lengths eliminate material waste. See how our cold-forged bolts achieve 15% higher tensile strength than ASTM standards:

Specification	DIN 931	DIN 933
Tensile Strength	1,000 MPa	1,200 MPa
Thread Length	Partial	Full

Manufacturer Showdown: Who Delivers Real Value?

While others charge $0.38/pc for DIN 931 bolts, we provide zinc-nickel coated variants at $0.32/pc. Our secret? Vertical integration cuts 22% production costs. Compare delivery times:

FAQS on din hex bolt

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

A: DIN 931 hex bolts have a partially threaded shank, while DIN 933 bolts are fully threaded. Both comply with ISO metric standards and are used for high-stress applications.

Q: Are DIN 975 and DIN 976 standards related to hex bolts?

A: DIN 975 and DIN 976 specify requirements for threaded rod lengths and packaging, not hex bolts. They are often used alongside DIN 931/933 bolts for extended fastening needs.

Q: When should I use a DIN 931 hex bolt over DIN 933?

A: Choose DIN 931 for applications requiring combined shear and thread load resistance. Opt for DIN 933 when full thread engagement across the entire shank is necessary.

Q: Do DIN 931 and DIN 933 hex bolts have the same material grades?

A: Yes, both DIN 931 and DIN 933 bolts are available in common grades like 8.8, 10.9, and A2/A4 stainless steel. Selection depends on environmental and mechanical requirements.

Q: Can DIN 975 threaded rods replace DIN 931 hex bolts?

A: No, DIN 975 rods lack a hex head for torque application. Use DIN 931 bolts where wrench tightening is required, and DIN 975 rods for custom-length threading.
