High Strength Flange Bolts for Wholesale Supply
10.9 级六角法兰螺栓批发供应商
XZ Fastener supplies Class 10.9 hex flange bolts for wholesale buyers serving machinery, automotive parts, construction hardware, equipment frames, brackets, distributor stock, and high clamp load assemblies. The integrated flange head helps spread load and can reduce the need for a separate washer in selected applications. Bolts can be supplied to DIN 6921, ISO 4162, or drawing requirements, with metric coarse or fine thread options according to order requirement. Wholesale orders can be packed by size, item code, carton, pallet, or assembly kit for organized receiving and inventory control.

What Buyers Should Know Before Sourcing Class 10.9 Hex Flange Bolts
Class 10.9 hex flange bolts are used where a high strength metric bolt and a larger bearing surface are needed in one part. When comparing 紧固件产品, buyers should confirm dimensional standard, flange diameter, head style, thread pitch, thread length, serrated or non-serrated flange, material, heat treatment, finish, and wholesale packing requirements.
The flange can help distribute load, but it should still be checked against the mating surface, slot size, clearance hole, and required clamp load. If an assembly requires special flange diameter, non-standard length, modified thread, or drawing-based geometry, XZ Fastener can review related 定制紧固件 together with the flange bolt order.

材质及牌号说明
Class 10.9 hex flange bolts are typically produced from heat treated medium carbon steel or alloy steel. The property class is selected for assemblies that need higher tensile strength than common general-purpose bolts, while the flange head provides a wider bearing surface under the head.
Compared with lower strength bolts, Class 10.9 bolts require closer control of heat treatment, thread quality, surface condition, and coating process. Buyers working with different metric standards can review the DIN和ISO紧固件标准指南 when comparing DIN 6921, ISO 4162, DIN 933, and related product descriptions.
牌号选择注意事项
- Class 10.9 is used for higher strength metric assemblies.
- Flange heads help spread load on compatible mating surfaces.
- Serrated flange options may increase resistance to loosening in selected applications.
- Mating threads, washers, and nuts should be matched to the bolt strength and finish.
表面处理选择指南
一般工业饰面
Black oxide and phosphate finishes are commonly selected for Class 10.9 flange bolts used in machinery, equipment, and controlled indoor environments. Zinc plated finish can be requested, but process control should be discussed because high strength bolts require careful handling of embrittlement risk.
面向腐蚀的饰面
Zinc flake coatings are often reviewed for higher corrosion resistance on high strength fasteners. Hot dip galvanized finish may be considered only when the full specification, dimensional fit, thread engagement, and application conditions are checked. Related 涂层紧固件 可以一起报价以获得一致的完成计划。
制造和质量控制
Class 10.9 hex flange bolts are produced through material preparation, forming, thread rolling, heat treatment, surface finishing, inspection, and packing. Wholesale supply control focuses on mechanical property, flange geometry, thread fit, surface finish, head dimensions, and packing accuracy according to order requirement.
For wholesale orders that include related 工业螺栓, nuts, and washers, XZ Fastener can help organize item-code sorting, mixed cartons, pallet labels, and inspection documents. This supports equipment assembly, construction hardware, and distributor stock replenishment with fewer receiving errors.
典型检查点
- 头部高度、对边尺寸、法兰直径和锯齿检查。
- 螺纹量规检查用于通配和非通配。
- 根据订单要求进行硬度和机械性能审查。
- 表面光洁度外观和涂层一致性检查。
- 装运前包装数量、纸箱标签、物品代码和托盘计划验证。
应用领域
- Automotive brackets, chassis parts, and equipment mounting points.
- Machinery frames, conveyor systems, and industrial equipment bases.
- 建筑五金件、钢支架、防护板和维护组件。
- 分销商库存、批发补货和组装紧固件套件。
Class 10.9 hex flange bolts are often chosen when buyers need a strong metric bolt with a built-in bearing surface. For assemblies that still require additional load distribution, XZ Fastener can review matching 平垫圈 and related parts according to the drawing and installation conditions.
如何获得更快的报价
To receive a clear quotation for Class 10.9 hex flange bolts, send the standard or drawing, diameter, pitch, length, thread length, flange type, finish, quantity, packing method, delivery destination, and inspection requirements.
