Spesifikasi Singkat
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 panduan pencocokan ukuran baut, mur, dan washer helps reduce mismatch before purchasing.
Pemeriksaan Sumber Penting

Penjelasan Materi dan Kelas
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.
Catatan Pencocokan Perakitan
- Diameter dalam harus sesuai dengan betis baut tanpa kelonggaran yang berlebihan.
- Diameter luar harus menopang area bantalan dan menutup lubang dengan benar.
- Chamfer orientation may matter when drawings specify contact direction.
- Kekerasan mesin cuci harus diperiksa untuk rakitan baut berkekuatan tinggi.
- Hasil akhir harus sesuai dengan hasil akhir baut dan mur, terutama untuk penggunaan di luar ruangan.
Panduan Pemilihan Permukaan Akhir
Berlapis Seng
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.
Oksida Hitam
Mesin cuci oksida hitam sering kali dipilih dengan baut oksida hitam DIN 933 untuk perlengkapan, mesin, dan rakitan yang dikontrol tampilannya. Peminyakan tambahan mungkin diperlukan untuk perlindungan penyimpanan.
Galvanis Celup Panas
Mesin cuci galvanis hot dip biasanya digunakan dengan baut DIN 933 galvanis hot dip untuk struktur baja luar ruangan. Pembeli harus mengkonfirmasi ketebalan lapisan dan kelonggaran dimensi sebelum memesan.
Untuk perbandingan pelapisan pada baut, mur, dan ring, tinjau panduan lapisan pengikat dan itu panduan pemilihan permukaan akhir untuk rakitan pengikat.
Manufaktur dan Kontrol Kualitas
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 kontrol kualitas untuk baut, mur, ring, dan sekrup untuk pembeli mempersiapkan persyaratan inspeksi.
