Head Type: Cup head, also known as a dome head or carriage bolt, features a smooth, rounded head with no external drive.
Shank Type: Smooth shank just below the head, transitioning to a threaded section.
Thread Diameter: 6mm (M6), which refers to the metric thread size.
Standard Compliance: DIN 603, which specifies the dimensions and tolerances for these bolts.

Usage:

Applications: Commonly used in wood-to-wood connections, wood-to-metal connections, and light-duty fastening tasks where the bolt head needs to sit flush with the surface.
Installation: The smooth, rounded head allows for a clean finish, often used with a washer and nut on the threaded end to secure materials together. The square section under the head grips into the part being fixed, preventing the bolt from turning when the nut is tightened.

Compliance with DIN 603:

Dimensional Accuracy: Ensures precise fit and compatibility with other DIN standard components.
Quality Control: Adherence to DIN 603 guarantees that the bolts meet stringent manufacturing and material quality standards.

These bolts are widely used in construction, woodworking, and various industrial applications due to their strength, durability, and resistance to corrosion.
