描述

高强度等级：严格达标10.9级高强度标准，抗拉强度≥1000MPa，屈服强度≥900MPa，强度远超普通8.8级螺栓，能应对中高载荷工况，是关键连接部位的优选。

加长规格定制：针对特殊安装深度、结构间距等场景，提供加长型规格，完美适配常规螺栓无法覆盖的特殊安装需求，安装适配性拉满。

蓝白锌防锈防护：采用优质蓝白锌电镀工艺，镀层均匀细腻，不仅外观清爽整洁，更能形成高效防护层，隔绝水汽、腐蚀介质侵蚀，大幅提升耐蚀性与使用寿命。

法兰一体防松：自带一体式法兰盘设计，无需额外搭配平垫片，即可增大受力面积、分散压力，同时增强防松抗震性能，适配震动频繁的工况，安装更稳固。

全流程品质管控：聚云锐20年紧固件制造经验，选用优质碳钢为原料，经冷镦成型、调质热处理、精密电镀等全流程自主生产，通过严格质检，每一颗螺栓品质可靠可追溯。

Ultra-High Strength Grade: Strictly meets Grade 10.9 high-strength standards, with tensile strength ≥1000MPa and yield strength ≥900MPa. Its strength is far higher than ordinary Grade 8.8 bolts, capable of handling medium-to-high load conditions, making it the preferred choice for key connection parts.
Extended Length Customization: Designed for special installation scenarios such as deep installation holes and large structural spacing, it provides extended length specifications to perfectly cover special installation needs that regular bolts cannot meet, maximizing installation adaptability.
Blue-White Zinc Rust Protection: Adopts high-quality blue-white zinc electroplating technology. The uniform and delicate coating not only presents a clean and tidy appearance but also forms an efficient protective layer to isolate water vapor and corrosive media, significantly improving corrosion resistance and service life.
Integrated Flange Anti-Loosening: Features a built-in integrated flange design, eliminating the need for additional flat washers. It can increase the stress area and disperse pressure, while enhancing anti-loosening and anti-vibration performance, suitable for vibration-prone working conditions for more stable installation.
Full-Process Quality Control: With 20 years of fastener manufacturing experience, Juyunrui uses high-quality carbon steel as raw material, independently producing through cold heading forming, quenching and tempering heat treatment, precision electroplating and other full processes. Strict quality inspection ensures the quality of each bolt is traceable.
