Din 604 bolt features and specifications are essential in understanding the lever of versatility, functionality and reliability which this fastener offers in distinct applications. Therefore, these features have been formulated to meet certain mechanical requirements and standards.
Material Composition
Usually, din 604 flat countersunk nib bolts are fabricated from a variety of materials to meet distinct corrosion resistance, strength and durability requirements. Some of the materials include stainless steel, high strength alloy steel, brass, bronze, copper-nickel alloys and zinc-coated steel.
Nib Features
Customarily, the nibs are designed to provide the bolt with additional grip within the application material. Also, it helps in preventing extraction, thus ensuring long-term stability. Commonly, Nibs are often found in various sizes and shapes, with the most common being circular, oval, and cross or star-shaped depending on the application requirements and on user’s preferences.
Corrosion Resistance
Internal corrosion resistance is one of the prominent features of the din 604 counter sunk bolts. Moreover, variations made from stainless steel, bronze, brass and copper-nickel alloys are preferred in environments that are likely to induce corrosion. This includes marine, chemical and outdoor settings. As for zinc-coated steel bolts, they provide cost-effective corrosion solutions for indoor environments.
Load Distribution
Usually, the countersunk design enables the bolt to sit flush within the surface. This distributes the load over a wider area. Therefore, this minimizes the risk of damage to the material being fastened. Hence, this making them ideal for applications in brittle materials which are likely to crack under pressure.
Strength and Durability
The materials from which din 604 flat countersunk nib bolts are fabricated are usually selected with their strength in mind.
