Spesifikasi Singkat
Yang Harus Diketahui Pembeli Sebelum Membeli Mur Torsi yang Berlaku ISO 7040
ISO 7040 prevailing torque nuts are hexagon lock nuts with a non-metallic insert that creates resistance on the mating bolt thread. They are used where vibration, movement, or service handling may loosen a standard hex nut. The insert material, temperature range, mating bolt grade, and thread condition should be checked before final selection.
These nuts are usually sourced as part of broader pengencang standar programs. Buyers should avoid mixing ISO 7040 descriptions with all-metal lock nuts because nylon insert behavior, reuse expectations, and temperature limits are different.

Penjelasan Materi dan Kelas
Baja Karbon dan Baja Paduan
Carbon steel and alloy steel ISO 7040 prevailing torque nuts are used where strength, cost control, and stable assembly performance are important. Property classes such as 5, 8, and 10 can be discussed according to mating bolt grade and application requirement. Heat treatment, thread accuracy, and insert retention should be checked during production control.
Pilihan Baja Tahan Karat
Mur pengunci baja tahan karat cocok untuk peralatan yang terkena kelembapan, penggunaan ringan di luar ruangan, dan aplikasi yang memerlukan peningkatan ketahanan terhadap korosi. Opsi A2 dan A4 dapat ditinjau berdasarkan permintaan. Pembeli harus memastikan bahan sisipan, kisaran suhu yang diharapkan, dan apakah diperlukan pasivasi atau pengepakan khusus.
Saat memilih mur ISO 7040 dengan yang lain produk pengikat, buyers should compare bolt grade, thread engagement, locking performance, and the service environment of the final assembly.
Panduan Pemilihan Permukaan Akhir
| Selesai | Penggunaan Khas | Pertimbangan Pembeli |
|---|---|---|
| Berlapis Seng | Mesin umum, rangka peralatan, dan stok distributor | Umum untuk mur pengunci baja karbon; warna lapisan dan target korosi dapat didiskusikan. |
| Oksida Hitam | Mesin, perkakas, perlengkapan, dan rakitan berpenampilan gelap di dalam ruangan | Usually requires oil protection; storage and packing conditions should be confirmed. |
| Berlapis Nikel | Komponen yang terlihat dan tampilan aplikasi yang terkontrol | Berguna ketika diperlukan permukaan yang lebih terang; konfirmasi lingkungan sebelum seleksi. |
| Baja Biasa | Penggunaan dalam ruangan yang terkontrol atau finishing sekunder | Perlindungan terhadap korosi terbatas; kondisi pengepakan dan penyimpanan itu penting. |
| Stainless Polos atau Pasif | Rakitan yang tahan lembab dan set pengikat tahan karat | Pasifasi dapat diminta untuk meningkatkan kebersihan dan konsistensi permukaan. |
For orders that combine lock nuts with plated bolts, washers, or other hardware, XZ Fastener can also supply pengencang berlapis sesuai dengan kebutuhan proyek.
