Overview
The din 603 furniture bolt is a type of furniture fastener that consists of a round, thin head and a square head. The square head of DIN 603 prevents the metal product from twisting at the installation site and makes the fastener much stronger.
Strength class of DIN 603 bolts
The strength class of a Din 603 bolt is the maximum applied force at which the bolt begins to fracture. Din 603 bolts are manufactured in strength classes from 4.6 to 8.8. From strength class 8.8, the bolt is considered high-strength,
DIN 603 fastening group
Depending on the material of manufacture, the din 603 hexagonal head bolt is divided into different fastening groups: High-strength fasteners - fasteners made of steel with a strength class of 8.8 or higher. Brass fasteners - fasteners are made of brass. Stainless fasteners - fasteners made of stainless steel.
Materials used for DIN 603 bolts
The technical characteristics of din 603 also directly depend on the material of the bolt.
The DIN 603 bolt is made of:
- Steel. The range of strength class of this material is 4.6-8.8. In addition, this material can be additionally coated:
1 Zinc for better corrosion protection if the product is to be used in aggressive environments.
2 Dacromet, this type of coating does not cause hydrogen embrittlement on steel. It also has electrically conductive properties; its more electronegative potential in relation to steel creates electrochemical protection in addition to barrier protection.
3 Zinc plate - it has similar properties to ordinary zinc, but the bolt looks matte.
4 Yellow zinc - similar properties to ordinary zinc, but the color of the bolt is different - yellow.
5 Hot-dip galvanized. Products with this coating are the most resistant to corrosion.
- Stainless steel A2, A4, A5. Allows the fasteners to be used at significant temperature changes and in aggressive and humid environments. Also, this material does not require additional coating.
- Brass. Brass bolts are used when the system is subjected to frequent dynamic, vibration, and cyclic loads.
Where are DIN 603 furniture bolts used?
DIN 603 bolts are most commonly used in the furniture industry: they are used in the manufacture of upholstered and cabinet furniture made of wood, chipboard and MDF. It is also widely used in other areas. For example, in construction to connect any wooden structures; in mechanical engineering to fasten components that require high precision. In addition, the DIN 603 bolt is used in the installation of road fences and bridge construction.
