Description:
Spring Nut: Spring Nuts - Core Materials
- Ordinary carbon steel: Suitable for regular civil and general construction scenarios, with excellent cost performance, need to be matched with surface anti-corrosion treatment.
- High-strength carbon steel (10B21/45# steel): Subjected to hardening heat treatment, with excellent tensile and torsion resistance, suitable for industrial assembly and outdoor construction main scenarios, need to be matched with surface anti-corrosion treatment.
- Stainless steel: Including mainstream grades 304/316, with inherent anti-corrosion and rust-proof properties, no additional anti-corrosion treatment required; 304 is suitable for humid outdoor scenarios, 316 is suitable for strong corrosion scenarios such as coastal high salt spray and chemical industry.
Spring Nuts - Surface Treatments
- Electro-galvanizing (blue-white zinc/color zinc): Basic anti-corrosion, suitable for indoor dry scenarios
- Hot-dip galvanizing: Superior anti-corrosion, wear-resistant, ideal for outdoor construction, the first choice for open-air engineering
- Mechanical galvanizing/Dacromet: High-grade anti-corrosion, no hydrogen embrittlement, suitable for coastal high salt spray, chemical industry and high-strength working conditions
- Passivation/Polishing: Exclusive for stainless steel, enhances corrosion stability and surface finish, no additional anti-corrosion treatment needed
Spring Nut is a kind of fastener, mainly used with bolts, screws, etc., to connect and fix various mechanical equipment, components and structures. Therefore, the application field of Spring Nut is very wide, including the following aspects:
1. Mechanical equipment field: such as machine tools, engineering machinery, agricultural machinery, etc.
2. Automotive, Marine, aviation fields: such as automobile tires, engines, aircraft engines, etc.
3. Construction, Bridges, highways, rail transit and other fields: such as connection structure, railway track fixing, etc.
4. Power, communication, instrumentation fields: such as power towers, communication equipment, CNC machine tools, etc. 5. Steel, petrochemical, mining, metallurgy and other fields: such as mining machinery, metallurgical equipment, etc.
The application range of nuts is quite wide, in fact, in a variety of mechanical equipment, the shadow of nuts can be seen everywhere. In industrial production, the nut is an essential fastener, and its importance is self-evident.
