What Are DIN6915 Heavy Hex Structural Nuts?
DIN6915 heavy hex structural nuts are professional HV friction-type matching nuts for European EN14399 steel structure systems. Compared with standard DIN934 ordinary nuts, DIN6915 nuts feature larger width across flats and thicker body for higher bearing capacity and uniform pressure distribution. Manufactured with quenched and tempered alloy steel to Class 10 strength, they form a complete structural connection set with DIN6914 bolts and DIN6916 washers, providing stable anti-slip performance for high-load steel structure projects.

How Are DIN6915 Heavy Hex Nuts Manufactured?
Material Selection: Premium 35CrMo/42CrMo alloy steel with stable mechanical properties.
Forging: Hot forging forming for compact internal structure and high load resistance.
Tapping: Precision 6H metric internal thread for perfect fitting with DIN6914 bolts.
Heat Treatment: Professional quenching and tempering to achieve stable Class 10 strength.
Finishing: Multiple anti-corrosion coatings for different working environments.
Quality Checks: Full batch testing for dimension, hardness and torque coefficient with official reports provided.
Difference Between DIN6915 and Ordinary DIN934 Nuts
Structural Design: DIN6915 is thick and enlarged structural type; DIN934 is thin standard nut for general use.
Strength Level: DIN6915 fixed Class 10 for heavy-load structural connection; DIN934 has no structural strength guarantee.
Application Scope: DIN6915 exclusive for European HV steel structure projects; DIN934 for general machinery assembly.
Compatibility: DIN6915 must be used with DIN6914 & DIN6916 as a complete set for engineering safety.
How to Choose the Right DIN6915 Structural Nuts?
Size Matching: Select exact DIN6915 nut size according to your DIN6914 bolt specification.
Environment Adaptation: Choose black finish for indoor use, HDG or Dacromet for outdoor and coastal corrosion conditions.
Complete Set Application: Always adopt full HV connection set to ensure stable friction coefficient and structural safety.
We specialize in complete EN standard HV structural fastener sets. Unified heat treatment and surface technology ensure consistent performance between bolts, nuts and washers, providing reliable one-stop fastening solutions for global structural projects.
What Are the Applications of DIN6915 Structural Nuts?
