What Buyers Should Know Before Sourcing ISO 7090 Steel Washers
ISO 7090 steel washers are chamfered plain washers designed to provide a controlled bearing surface in metric bolted assemblies. Compared with basic flat washers, the chamfered edge can be important where drawings specify washer orientation, surface contact, or a cleaner fit under bolt heads and nuts.
Before ordering, buyers should confirm inner diameter, outer diameter, thickness, chamfer detail, hardness, material, surface finish, and whether the project allows ISO 7089 or DIN 125 alternatives. For complete assembly planning, the XZ Fastener 螺栓、螺母和垫圈尺寸匹配指南 helps reduce mismatch before purchasing.
重要的采购检查
- Confirm ISO 7090, nominal size, inner diameter, outer diameter, thickness, and chamfer requirement.
- 指定垫圈硬度，例如 140 HV、200 HV 或 300 HV。
- 将垫圈尺寸与螺栓直径、孔尺寸、螺母面和轴承表面相匹配。
- Check coating thickness when washers are used with galvanized or coated fasteners.
- Confirm carton weight, small box packing, palletizing, and buyer label requirements.

材质及牌号说明
Carbon steel ISO 7090 steel washers are commonly used for machinery, brackets, frames, construction hardware, and general equipment assembly. Hardened steel washers may be selected for higher clamp loads or high-strength bolt assemblies. Stainless steel A2 and A4 washers are preferred where corrosion resistance is more important than carbon steel hardness.
Washer hardness should be reviewed when the assembly uses Grade 8.8 carbon steel hex bolts, 10.9 bolts, or 12.9 bolts. For controlled fastening, the washer should support the bolt head or nut face without excessive deformation. ISO 7090 washers are commonly used with metric hex head bolts, ISO 4032 nuts, and DIN 127 spring lock washers in complete fastening sets.
装配匹配注意事项
- 内径必须适合螺栓杆，不得过度松动。
- 外径应支撑轴承区域并正确覆盖孔。
- Chamfer orientation may matter when drawings specify contact direction.
- 对于高强度螺栓组件应检查垫圈硬度。
- 表面处理应与螺栓和螺母的表面处理相匹配，特别是在室外使用时。
表面处理选择指南
镀锌
Zinc plated ISO 7090 washers are commonly used with zinc plated DIN 933 bolts for indoor machinery, equipment, brackets, and general industrial fastening. White zinc and yellow zinc can be discussed by order.
黑色氧化
黑色氧化垫圈通常与黑色氧化DIN 933 螺栓一起选择，用于固定装置、机械和外观控制组件。可能需要额外涂油以保护储存。
热镀锌
热镀锌垫圈常与室外钢结构热镀锌DIN 933螺栓配套使用。买家在订购前应确认涂层厚度和尺寸余量。
对于螺栓、螺母和垫圈的涂层比较，请查看 紧固件涂层指南 和 紧固件组件表面光洁度选择指南.
制造和质量控制
ISO 7090 steel washer production requires control of stamping accuracy, inner diameter, outer diameter, thickness, chamfer, flatness, burr condition, surface appearance, hardness, and coating coverage. For hardened steel washers, heat treatment and hardness testing are important before final finishing. For coated washers, chamfer edges and holes should be reviewed for complete coverage and burr condition.
Quality checks can include material verification, dimensional inspection, chamfer inspection, hardness testing, flatness review, coating thickness testing, salt spray testing when requested, and final packing inspection. XZ Fastener shares more details about 螺栓、螺母、垫圈和螺钉的质量控制 供买家准备检验要求。
