Grade 4.8/8.8/10.9/12.9 High Quality DIN931 DIN933 Bolts

DIN 933 and DIN 931 bolts are both hexagonal head bolts under the German Industrial Standard (DIN). The main differences between them lie in the thread length and some dimensional tolerances. Below is a detailed introduction to them:

DIN 933 Hex Bolts

Definition and Characteristics: DIN 933 is the standard for fully threaded hexagonal head bolts. Its characteristic is that the bolt thread extends along the entire length of the bolt, providing a stronger and more reliable connection. The bolt head is hexagonal, facilitating tightening and loosening with a wrench or socket.

Size Specifications: This standard specifies hexagonal head bolt sizes from M1.6 to M52. Product grades are divided into A and B. Grade A bolts have a maximum size of M24 and a length not exceeding 10d or 150mm (d is the nominal bolt diameter). Bolts larger than M24 or longer than 10d or 150mm are Grade B bolts. When the bolt size is not larger than M4, the end is not required to be chamfered.

Materials and Surface Treatments: The standard does not specify specific materials or coatings. Common materials include carbon steel and stainless steel, which can be selected according to specific applications and requirements. Various surface treatments are available, such as hot-dip galvanizing and electroplating, to meet different corrosion resistance and aesthetic requirements.

DIN 931 Hex Bolts

Definition and Characteristics: DIN 931 is the standard for hexagonal head bolts with a coarse shank and a smooth shank. Only half of the shank is threaded, while the other half is smooth. This design ensures a tight connection and provides better guidance during installation, distributing stress effectively under tensile and shear forces.

Size Specifications: The DIN 931 standard is based on metric measurements, with dimensions in millimeters. Sizes typically range from M5 to M24, but specific dimensions may vary depending on the application and standard requirements.

Materials and Properties: Materials include carbon steel and stainless steel. Common strength grades include 8.8 and 10.9.

DIN933 and DIN931 Bolt Features:

Product Grade	Grades A/B, by size/length	Grades A/B, same as DIN933
Head Feature	Slightly larger hex, rounded	Slightly smaller hex, square
Application	General fastening for strong joints	Structural joints bearing tension/shear

DIN933 DIN931 Cold Heading Process

DIN933 and DIN931 bolts are typically manufactured using a cold heading process.

The cold heading process involves cutting wire to the required length at room temperature using a cold heading machine, then repeatedly pressing the steel with a die to form the bolt head and shank shape during plastic deformation. Finally, the threads are rolled onto the bolt using a thread rolling machine. This process offers advantages such as high production efficiency, high material utilization, and good bolt quality, meeting the precision and performance requirements of DIN933 and DIN931 bolts.
