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:

Easy Hand Tightening: The knurled pattern allows for easy manual tightening without tools .Enhanced Grip: Provides a better grip, preventing fingers from slipping during tightening or releasing .

Scope of
