Product Characteristics:
Nuts are essential components in fastening systems, serving to secure bolts or screws in place. They come in diverse shapes and sizes to accommodate various threading systems and applications, offering crucial support and stability in assemblies.
Production Process:
Nuts undergo several manufacturing stages, including forging, machining, heat treatment, and surface finishing. Cold or hot forging shapes the initial form of the nut, followed by precise machining to refine dimensions and threading. Heat treatment processes enhance mechanical properties, while surface finishing improves corrosion resistance and aesthetics.
Custom machined nuts require precise dimensions and threading to ensure proper engagement with bolts or screws. Stringent quality control measures, including accurate machining and threading processes, maintain tight tolerances to guarantee compatibility and reliability in assembly.The products we produce can reach ±0.02, 0 PPM quality yield rate
Product Hardness:
Custom machined nuts are engineered to possess specific hardness levels, typically achieved through appropriate material selection and heat treatment processes. The hardness ensures resistance to deformation and wear, contributing to the overall durability and performance of the nut.
Carbon steel nuts are classified into various hardness grades, typically ranging from 4, 5, 6, 8, 10, to 12. These grades denote the minimum tensile strength and yield strength of the nuts. For example, Grade 12 nuts typically have a minimum tensile strength of 1,200 MPa and a minimum yield strength of 1,080 MPa.
Nuts are fabricated from various materials to suit specific requirements. Common materials include carbon steel, stainless steel, alloy steel, brass, and aluminum. Each material offers distinct properties such as strength, corrosion resistance, and temperature tolerance, catering to diverse applications and environmental conditions.
Usage Scenarios:
Nuts find extensive application across industries such as automotive, construction, aerospace, machinery, and electronics. They are essential for securely fastening components together, providing structural integrity and stability in various assemblies, ranging from household appliances to heavy machinery and aerospace structures.Welcome to inquire us for custom nuts, we are a professional nut and bolt company.
