Standard DIN 960 covers high-strength hex head bolts with a fine thread covering a specific section of the shank. The thread is designed for fitting a nut with a washer underneath to form a detachable joint fastening various structures.

Parameters and technical specifications of fine-thread bolts

The German standard DIN 960 has equivalents: the European standard ISO 8765 and the Russian GOSTs 15589-70, 7798, 7805. If the manufacturer has indicated any of these standards in the marking or quality passport, the product meets the following requirements:

• fine-pitch, partial thread with sizes from M8 to M64;

• product length ranges from 35-400 mm;

Carbon steel with property classes 5.6, 8.8, 10.9, 12.9, brass and stainless steel grades A1-A5 are used to manufacture the fasteners. Items made of plain steel can be zinc-plated by electroplating, but uncoated items are also available. These are to be painted after installation. There is a special type of DIN 960 fine-thread bolt made of frost-resistant steel 110KhL. This fastener is intended for installation work in the Far North regions.

Where high-strength fine-thread bolts are used

The main purpose of the DIN 960 fine-thread bolt is to provide a strong and reliable connection of massive elements and structures operating under high load. The fine-pitch thread eliminates play in the detachable joint, unlike fasteners with coarse thread.

The main field of application is machine building and the installation of structural steel of various purposes. Standard DIN 934 nuts and lock nuts help create a strong detachable joint. The assembly can additionally be fitted with a flat washer made of hardened metal or lock washers.
