Countersunk head bolt with low square headrest DIN 608

Countersunk head bolt with low square headrest DIN 608

When designing this screw, the developers first of all tried to create a universal fastener that will be widely used in any production and industrial areas, especially the DIN 608 countersunk head bolt with low square head is suitable for furniture production. Based on the results of our research and analysis of customer feedback, we can draw a disappointing conclusion that it cannot be used for rigidly joining both wooden and composite surfaces.

Practice shows that this metal product is suitable for fastening designer luxury furniture made from rare hardwoods, as well as for joining chipboard, plywood, fiberboard, MDF, OSB, and WPC.

The main distinguishing characteristics of this product:

It is made of steel with a strength class of 4.6 or 8.8, sometimes brass is used;
can be coated (zinc) or uncoated;
metric threads are usually incomplete from M10 to M12;
The length of the finished product is 25-50 (mm).

This product is often used with a hexagonal nut and flat washer of the same diameter, which ensures the reliability of each connection. Due to its design, the screw is mounted with a square headrest, and the flat cap makes the attachment point almost invisible. In addition, this fastener design prevents the bolt from twisting in the finished product during operation, which increases its service life.
