Strength and Precision in Hex Head Bolt Half Thread

The Hex Head Bolt Half Thread (DIN 931) is designed for applications requiring a combination of strength and precision. With partial threading, this bolt provides increased clamping force, making it ideal for use in construction, heavy machinery, and industrial installations. Its hexagonal head allows for easy tightening and loosening, while its robust design ensures long-lasting performance in high-stress environments.

LET YOUR CONFUSSION GET PASSED AWAY!

A HEX HEAD BOLT HALF THREAD (DIN 931) is a type of bolt with a hexagonal head and a partially threaded shank. The threading extends only halfway down the length of the bolt, allowing for a stronger grip in applications where only partial threading is needed.
DIN 931 hex head bolts are available in a wide range of sizes, from M5 to M64 in diameter, with various lengths. You can select the appropriate size based on the material thickness and the clamping requirements of your project.
To prevent loosening, you can use locking washers, thread-locking compounds (like Loctite), or double-nut techniques. Proper tightening with the recommended torque also helps reduce the chances of bolt loosening due to vibration or load fluctuations.
The half-thread design allows for better load distribution and increased strength in shear applications. The unthreaded section provides a solid surface for bearing loads, making it suitable for high-stress environments like structural assemblies.
The main difference between DIN 931 and DIN 933 bolts is the threading. DIN 931 specifies hex head bolts with partial threads, while DIN 933 specifies fully threaded hex head bolts. DIN 931 bolts are often used when the unthreaded portion of the bolt provides added shear strength.
