买家在采购DIN 444 吊环螺栓之前应了解什么

DIN 444 eye bolts are often purchased for linkage and adjustment work, not simply as general threaded fasteners. The eye inner diameter, eye thickness, shank length, thread length, and transition radius can affect fit with pins, hooks, brackets, and mating hardware.

Buyers should also separate DIN 444 from lifting eye bolts such as DIN 580. If the application involves lifting, suspension, or safety-critical loading, the required proof test, working load requirement, inspection method, and engineering approval must be stated separately. For ordinary linkage or clamping work, clear dimensions and material grade are usually the first priority.

For related sourcing, buyers can compare DIN 444 with other 工业螺栓 和 标准紧固件.

常见采购说明

A clear RFQ helps confirm production method, inspection scope, packing, and export documentation. Common purchasing descriptions include:

• DIN 444 吊环螺栓，M8 x 60，4.8 级，镀锌，吊环内径由图纸确认。
• DIN 444 eye bolt, M10 x 80, Class 8.8 carbon steel, black oxide, supplied with nut and washer.
• DIN 444 吊环螺栓，M12 x 100，不锈钢 A2-70，钝化处理，小盒包装。
• DIN 444 公制吊环螺栓，混合尺寸，热浸镀锌，需要出口托盘和尺寸报告。

制造和质量控制

DIN 444 eye bolt export supply requires control over forming, eye geometry, shank straightness, thread rolling, heat treatment where required, surface finishing, and final packing. The eye area must be checked for cracks, heavy folds, sharp burrs, poor transition surfaces, and dimensional inconsistency.

出口质量控制点

1. 查看DIN 444 表格、尺寸列表、图纸注释、材料、等级、表面处理和包装要求。
2. 需要时确认原材料等级和炉号可追溯性。
3. 检查孔眼内径、孔眼外径、孔眼厚度、柄长和柄直线度。
4. 验证螺纹螺距、螺纹长度、通/止规配合以及毛刺状况。
5. 根据适用的规定性能等级进行热处理。
6. 表面处理后检查涂层外观、覆盖率、螺纹功能和眼距。
7. Pack by item code, size, grade, finish, and batch number for export receiving control.

对于非标准眼睛尺寸或基于图纸的零件，XZ Fastener 可以通过其审核要求 定制服务。比较DIN参考的买家也可以使用 DIN和ISO紧固件标准指南.

应用领域

DIN 444 吊环螺栓用于螺纹杆必须与销、钩、连杆、支架或可调节夹紧点连接的情况。常见应用包括：

• 机械铰链和枢轴连接。
• 夹具、夹具和可调节工具。
• 用于防护装置、面板和轻型框架的张紧系统。
• 建筑五金件、支架和工业设备组件。
• 不同尺寸和表面处理的公制吊环螺栓的经销商库存计划。

当装配需要匹配时 工业螺母 或 平垫圈，将它们包含在同一询价中，以便可以一起检查螺纹配合和包装。

如何获得更快的报价

Export quotation is faster when the RFQ includes dimensional, packing, and document requirements at the beginning. For DIN 444 eye bolts, the eye dimension is as important as the thread size.
