Yang Harus Diketahui Pembeli Sebelum Membeli Sekrup Soket Stainless Steel A4-80
Wholesale sourcing should focus on consistent sizes, repeatable thread quality, stable packing, clear labels, and correct material separation. A4-80 stainless steel socket screws should be specified by standard, head type, internal hex drive, diameter, length, thread pitch, property class, finish, carton quantity, and inspection requirement.
Confirm socket screw geometry
DIN 912 and ISO 4762 are common references for socket head cap screws, while low head, button head, countersunk head, and shoulder socket screws use different dimensions. Buyers can review related baut tutup soket kepala Allen metrik when building a standard stock list.
Check A4-80 stock and production suitability
A4-80 is a higher stainless property class than A4-70. For larger diameters, special lengths, fine pitch threads, or custom designs, availability and mechanical requirements should be checked before confirming a wholesale program.
Plan packing for receiving and resale
Wholesale buyers often need inner boxes, barcode labels, carton marks, pallet separation, and consistent carton weight. These details help warehouses receive, sort, and resell the screws without unnecessary rework.
Deskripsi Pembelian Umum
Clear purchasing descriptions reduce confirmation time and help avoid wrong head style or wrong stainless property class. Typical wholesale wording includes:

Penjelasan Materi dan Kelas
Baja tahan karat A4 adalah kelompok tahan karat austenitik yang mengandung molibdenum yang sering dipilih untuk udara laut, kelembapan luar ruangan, paparan klorida, peralatan kimia, dan lingkungan korosif lainnya. A4-80 mengidentifikasi kelas properti tahan karat berkekuatan lebih tinggi daripada A4-70, umumnya dikaitkan dengan tingkat kekuatan tarik minimum 800 MPa dalam kondisi referensi ISO 3506.
For distributors deciding which stainless socket screws to stock, the choice between A2-70, A4-70, and A4-80 should consider end-user applications, corrosion exposure, required clamp load, mating material, tightening method, and galling risk. XZ Fastener explains these differences in its guide to baut baja tahan karat kelas A2-70, A4-70, dan A4-80.
A4-80 stainless socket screws are not automatic substitutes for alloy steel socket head cap screws. Alloy steel may offer higher strength, while A4-80 is chosen when stainless corrosion resistance is a key requirement.
Inspection can include head dimensions, socket drive quality, thread fit, surface condition, material documents, labels, and packing checks.
Panduan Pemilihan Permukaan Akhir
A4-80 stainless steel socket screws are commonly supplied in plain stainless or passivated finish. Passivation helps remove free iron contamination and supports the natural stainless protective layer. Pickling and passivation may be discussed for cleaner stainless surfaces. Lubrication can be important for A4-80 socket screws because stainless threads may gall under high tightening pressure.
| Selesai | Penggunaan Grosir Biasa | Catatan Pembeli |
|---|---|---|
| tahan karat polos | General machinery, repair stock, standard stainless socket screw programs | Hasil akhir yang umum ketika tidak ada perawatan permukaan tambahan yang ditentukan. |
| Pasif | Udara laut, peralatan luar ruangan, mesin kimia, rakitan tahan karat yang bersih | Often requested where corrosion resistance and clean surface are important. |
| Acar dan dipasivasi | Persyaratan pembersihan permukaan tahan karat yang lebih menuntut | Konfirmasikan ekspektasi penampilan dan kriteria penerimaan sebelum produksi. |
| Dilumasi | Beban penjepit lebih tinggi, perakitan berulang, aplikasi sensitif terhadap rasa sakit | Perilaku torsi berubah ketika pelumasan digunakan. |
| Pelapis baja karbon | Baut DIN 933 berlapis seng, baut DIN 933 oksida hitam, baut DIN 933 galvanis hot dip | Uraian ini biasanya berlaku untuk baut segi enam baja karbon, bukan sekrup soket tahan karat A4 standar. |
