Metric DIN number of fasteners
Every industry uses certain fasteners to assemble different materials and parts together. Anything that fixes one object to another is a fastener, including screws, nails, hinges, snaps, and rivets. Some fasteners use the metric system, while others use the UNC or UNF style, which is based on measuring fasteners in inches. Many fastener manufacturers can manufacture metric and inch fasteners to meet the needs of all customers, but you can also find metric fastener manufacturers that only manufacture metric fasteners.

 

Metric fastener manufacturers will provide a variety of fastener sizes and types in metric systems. Most metric manufacturers will use the following common DIN numbers:

 

Hexagon head screws: Hexagon head screws can have a thicker pitch or a thinner pitch. Common coarse pitch numbers include 931 and 933, and fine pitch pitches include 930 and 961.

 

Screws: Screws have many uses, and are usually used to fix heavy machinery parts or other heavy materials together. The DIN number of most screws is 971, and the pitch and grade can be customized.

Nuts: Nuts are an important part of many fastening mechanisms. Common types of nuts include hex nuts and nylon lock nuts. The DIN numbers of nuts include 934, 985 and 980V.

 

Washers: Washers help to hold screws and nuts in place without peeling off the metal or damaging the material that connects the screws to the base material. The DIN numbers for washers include 125 for flat washers and 127 for lock washers.

 

Sleeve: The sleeve may include a sleeve head screw, a flat head sleeve head screw, and a sleeve fixing screw. DIN numbers include 912, 7191 and 916.

 

Machine screw: The machine screw can have a flat-head Phillips head of DIN 7985 or a flat-head Phillips head of DIN 965.
