Stainless Steel 304 Shoulder Bolt Metric M10x30 Zinc Plating White Automotive Assembly
Stainless Steel 304 Shoulder Bolt Metric M10x30 Zinc Plating White Automotive Assembly
1,Description:
This metric M10x30 304 stainless steel shoulder bolt is customized exclusively for mainstream automotive assembly production scenarios, adopting food-grade white zinc plating surface treatment to upgrade overall anti-corrosion and anti-oxidation performance for long-term vehicle operating environments. Made of standard national certified 304 austenitic stainless steel raw material, the bolt integrates excellent toughness, rust resistance and mechanical stability, which can adapt to high-frequency vibration, temperature alternation and humid chassis working conditions inside passenger cars, new energy commercial vehicles and automotive interior assembly structures. The integrated one-piece shoulder step structure is precisely CNC machined with micron-level tolerance control, ensuring zero deviation for positioning assembly, limiting installation gap and avoiding bolt offset loosening during vehicle driving vibration. The white zinc plating layer forms a compact protective film on the metal surface, effectively isolating rainwater splash, road salt fog and automotive lubricant erosion, greatly extending service life compared with ordinary carbon steel fasteners. Standard metric M10 thread adopts full tooth uniform rolling process, with smooth thread surface, high matching precision and strong locking friction, compatible with standard metric prefabricated holes of automotive plastic brackets, metal connecting plates and suspension auxiliary parts. This fastener undergoes strict hardness testing, salt spray testing and torsion testing before delivery, meeting ISO automotive fastener manufacturing standards. It is widely applied for fixed positioning of automotive door hinge assemblies, instrument panel brackets, cooling module connecting frames and body auxiliary limit structures. It features easy manual and mechanical installation, reusable disassembly and assembly performance, no surface peeling or thread sliding after long-term use, stable clamping force, low later maintenance cost, and is a universal anti-rust positioning fastener for medium load automotive assembly links
2,Applications:
Material Composition & Maintenance Guide: 304 Austenitic Stainless Steel chemical composition: 18% chromium, 8% nickel, less than 0.08% carbon, balanced iron base alloy without magnetic property. Material maintenance rules: Keep white zinc plating surface away from strong acid detergent and road deicing salt long-term contact; wipe surface dust regularly with neutral water-based rag; avoid brute-force tapping to prevent zinc coating cracking; store in dry ventilated warehouse, no mixed placement with corrosive chemical raw materials; polish tiny coating scratches with wax polish to avoid base metal oxidation.
3,Technical Advantages
Chemical inertness constitutes another fundamental protective function of PTFE coatings. The dense fluorine shield surrounding the carbon backbone resists attack from virtually all chemical agents including strong acids such as sulfuric and hydrochloric acid, strong bases including sodium hydroxide, organic solvents, oxidizing agents, and corrosive salts. This universal chemical resistance makes PTFE-coated components indispensable in chemical processing equipment, laboratory apparatus, semiconductor manufacturing tools, and pharmaceutical production lines where exposure to aggressive media occurs routinely. Unlike metallic coatings that may dissolve or degrade, or organic paints that blister and peel under chemical attack, PTFE maintains structural integrity and surface functionality across extreme pH ranges and concentrated chemical environments.
