GB808/Din431 Small Hex Extra Flat Nut is a specially designed nut with a small hex head and a very flat profile. These nuts are usually used in applications that require a very low profile or ultra-thin design, such as in machinery, electronic equipment and some precision instruments.

Material: including carbon steel, alloy steel, stainless steel (such as 304, 316, 316L, etc.) and other materials, the specific selection depends on the working environment and application requirements.

Grade: The product grade is different mechanical properties grade (such as 4.8 grade, 8.8 grade, 10.9 grade,A2-70, etc.), these grades reflect the tensile strength, yield strength and other mechanical properties of the bolt. Different grades are suitable for different load bearing requirements and working environments.

Advantage:

1. Ultra-thin design: the flat design allows the nut to be used in space-constrained environments. 2. Small Hex Design: Smaller hex head allows for less space to be occupied. 3. High strength: Despite the flat profile, it still provides sufficient strength and stability.

Scope of 

Application

1.Precision Instruments: In precision instruments, in order to maintain the compactness of the overall design, this ultra-flat nut may be used. 2. Electronic equipment: In electronic equipment, especially in space-constrained environments, this nut can provide a good fixing solution. 3. mechanical assemblies: in mechanical assemblies, when it is necessary to minimize the impact of the nut on the overall size of the equipment, this nut is ideal.
