Product Description
Hexagonal nuts are designed to work in conjunction with bolts and screws to provide secure fastening for machine parts. These Class 4.8 Grade 8.8 carbon steel nuts with black plating offer excellent durability and performance in various industrial applications.
Types and Applications
Hexagonal nuts are categorized into three types based on nominal thickness: Type I, Type II, and thin nuts. Type I hexagonal nuts are the most commonly used, with A and B grades suitable for precision applications requiring smooth surfaces, while C grade is ideal for rougher surfaces. Type II nuts feature greater thickness for frequent assembly/disassembly applications.
Key Features
Excellent torque transmission capacity
High resistance to axial and radial loads
Available in multiple grades and specifications
Black plating for corrosion resistance
Manufactured to DIN standards
Common Applications
Construction: Steel structures, bridges, and building frameworks
Mechanical Engineering: Automotive, marine, aviation, and machine tool components
Electronics: Secure fastening of electronic components
Home Maintenance: Furniture assembly and bicycle repairs
Bolt and Nut Grade Matching
For optimal performance, match bolt grades with corresponding nut grades. An 8.8 grade bolt should be paired with an 8 grade nut, as the bolt's yield strength is 80% of its tensile strength. This ensures balanced performance and easier maintenance, as nuts typically fail before bolts.
