Product Description
The 4.6 Nut Bolt is a mild steel fastener characterized by its grade 4.6 classification. This indicates a tensile strength of 400 MPa and a yield strength of 240 MPa. These bolts are ideal for general-purpose applications where moderate strength and durability are required.
- Material: High-grade mild steel
- Finish: Zinc-plated, black oxide, or custom finishes available
- Threading: Precision-engineered for compatibility and ease of use
- Applications: Suitable for light to medium-load applications
What is the Difference Between 4.6 Nut Bolt and Other Nut Bolts?
- Strength:
The grade 4.6 Nut Bolt has moderate tensile strength compared to higher-grade bolts such as 8.8, which are used for heavy-load applications. - Material:
4.6 Nut Bolts are typically made of mild steel, while higher grades may use alloy steel for added strength and hardness. - Cost:
4.6 Nut Bolts are cost-effective and suitable for general-purpose applications, making them an economical choice compared to high-grade bolts. - Applications:
While higher-grade bolts are used in critical structures like bridges or high-stress environments, 4.6 Nut Bolts are perfect for routine industrial and construction tasks.
Where Can We Use 4.6 Nut Bolts?
- Construction Projects: Ideal for assembling steel frameworks and lightweight structures.
- Automotive Industry: Used in components requiring moderate strength.
- Machinery: Suitable for equipment assembly where high tensile strength is not critical.
- Furniture Manufacturing: Used in fittings and assemblies.
