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 Guía de coincidencia de tamaños de pernos, tuercas y arandelas. helps reduce mismatch before purchasing.
Comprobaciones de abastecimiento importantes
- Confirm ISO 7090, nominal size, inner diameter, outer diameter, thickness, and chamfer requirement.
- Especifique la dureza de la arandela, como 140 HV, 200 HV o 300 HV.
- Haga coincidir el tamaño de la arandela con el diámetro del perno, el tamaño del orificio, la cara de la tuerca y la superficie del cojinete.
- Check coating thickness when washers are used with galvanized or coated fasteners.
- Confirm carton weight, small box packing, palletizing, and buyer label requirements.

Explicación de materiales y grados
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.
Notas de coincidencia de ensamblaje
- El diámetro interior debe ajustarse al vástago del perno sin holgura excesiva.
- El diámetro exterior debe soportar el área del rodamiento y cubrir el orificio adecuadamente.
- Chamfer orientation may matter when drawings specify contact direction.
- Se debe verificar la dureza de la arandela para conjuntos de pernos de alta resistencia.
- El acabado debe coincidir con el acabado del perno y la tuerca, especialmente para uso en exteriores.
Guía de selección de acabado superficial
zincado
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.
óxido negro
Las arandelas óxido negro a menudo se seleccionan con pernos óxido negro DIN 933 para accesorios, maquinaria y conjuntos de apariencia controlada. Es posible que se requiera lubricación adicional para proteger el almacenamiento.
galvanizado en caliente
Las arandelas galvanizado en caliente se usan comúnmente con los pernos galvanizado en caliente DIN 933 para estructuras de acero para exteriores. Los compradores deben confirmar el espesor del recubrimiento y el margen dimensional antes de realizar el pedido.
Para comparar el recubrimiento entre pernos, tuercas y arandelas, revise la guía de revestimiento de sujetadores y el Guía de selección de acabado superficial para conjuntos de sujetadores..
Manufactura y Control de Calidad
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.
