Customized M9*35*17.5 Stainless Steel Hexagonal Screws

Advantages​​
1.​​High-Strength Fastening​​
• Made of stainless steel or alloy steel with excellent tensile strength, specifically designed for critical connections such as engine blocks and chassis, effectively preventing loosening.
• Precision-engineered thread structure ensures tight engagement, vibration resistance, and long-lasting reliability.
2.​​Outstanding Durability​​
• Withstands extreme temperatures (800°C+) and high-pressure environments, effortlessly handling demanding engine conditions.
• Excellent oxidation and corrosion resistance, protecting against moisture, oil, and chemical exposure, significantly extending service life.
3.​​Leak-Proof Sealing​​
• Paired with specialized gaskets or tapered thread design, it ensures effective sealing for combustion chambers and oil passages, preventing gas or fluid leakage.
​​Product Features​​
• ​​Material & Craftsmanship​​: Cold-forged from austenitic stainless steel with optional zinc plating or passivation treatment, combining strength with aesthetics.
• ​​Comprehensive Specifications​​: Available in various metric/imperial sizes with fine/coarse thread options, compatible with mainstream vehicles (e.g., Japanese, German) and custom modifications.
• ​​Precise Torque Control​​: Pre-set torque coefficient ensures even force distribution during installation, preventing overtightening (fracture) or under-tightening (leakage).
​​Cost Efficiency​​
• ​​Economical & Durable​​: Compared to low-quality screws requiring frequent replacement, these bolts resist rust and deformation, reducing long-term maintenance costs.
• ​​Risk Mitigation​​: Eliminates major failures like engine cylinder scoring or gasket burnout caused by bolt failure, saving substantial repair expenses.
​​Applications​​
• ​​Vehicle Compatibility​​: Suitable for sedans, SUVs, and commercial vehicles (including gasoline, diesel, and new energy powertrains).
• ​​Key Installation Points​​: Cylinder heads, turbochargers, exhaust systems, suspension components, and other high-stress areas.
