Product Details

Product Introduction

Hexagon nuts manufactured according to DIN 555, the German specification for grade‑C metric hexagon nuts. This standard covers a full metric thread range from M5 to M100. Produced from premium carbon steel, these nuts are offered in various strength classes to meet different load demands. Multiple surface finishes can be customized for various indoor and outdoor working environments. Compared with high‑precision nuts, DIN 555 features wider dimensional tolerances and is widely used for non‑precision general assembly.

Material & Mechanical Properties

Cold forged from high‑quality carbon steel. Higher strength grades undergo strict heat treatment for stable hardness and reliable bearing capacity. Material inspection reports can be supplied upon request. Carbon steel DIN 555 nuts deliver dependable clamping performance for conventional static and low‑vibration fastening scenarios.

Geometry & Thread Form

Manufactured strictly following the dimensional requirements of DIN 555. The standard hexagon profile fits regular wrenches for easy installation. Precision metric internal threads ensure smooth screwing and stable locking. With grade‑C tolerance, this series is suitable for projects with less strict precision requirements.

Corrosion Protection

Common surface treatments include plain finish for regular use, black oxide, electro zinc plating for daily rust prevention, and hot‑dip galvanizing for outdoor and corrosive environments. Appropriate coatings can be selected based on actual application conditions.

Application Suitability

DIN 555 carbon‑steel hexagon nuts are widely used in general construction, agricultural machinery, ordinary steel structures and conventional industrial assembly, perfectly matching corresponding metric bolts for standard fastening.
