Features of DIN 931 Hex Bolts:

Material: Hex bolts according to DIN 931 can be made from various materials, including carbon steel, alloy steel, stainless steel, and other materials, depending on the application requirements. The choice of material depends on factors such as strength, corrosion resistance, and environmental conditions.
Thread Type: DIN 931 hex bolts have metric threads with a partial thread design. The partial threading leaves an unthreaded portion under the head, which provides a clamping area when fastening.
Hex Head: These bolts have a hexagonal head, which is designed for use with a wrench or socket for tightening and loosening.
Length: DIN 931 specifies the overall length of the bolt, including the threaded and unthreaded portions. The length can vary depending on the specific design and application requirements.
Thread Length: The standard provides information about the length of the threaded section, which can also vary according to the design and application needs.
Thread Tolerance: DIN 931 includes information about thread tolerances, ensuring the compatibility of the bolts with nuts and threaded holes.
