Penjelasan Materi dan Kelas
Blue zinc plated self tapping screws are commonly made from carbon steel or 10B21 when case hardening and thread-forming performance are required. Low carbon steel can be suitable for lighter applications, while boron-treated steel can be reviewed for stronger tapping performance after heat treatment.
Buyers should confirm whether the screw needs surface hardness, core hardness, case depth, torsion performance, or a specific material grade. If the screw will be installed with an automated driver, include bit type, torque range, pilot hole size, and mating material in the inquiry.
Panduan Pemilihan Permukaan Akhir
- Blue zinc plated: common blue-white zinc finish for clean appearance and general indoor corrosion protection.
- Seng trivalen: sering diminta untuk mengendalikan persyaratan lingkungan dan spesifik pelanggan.
- Seng bening: selected when a silver tone is preferred for visible hardware.
- Oksida hitam: cocok untuk sekrup peralatan dalam ruangan di mana tampilan gelap dan perlindungan minyak dapat diterima.
- Fosfat: dipilih untuk aplikasi retensi oli, kontrol gesekan, atau adhesi cat.
- Seng nikel: dipertimbangkan ketika kinerja korosi yang lebih tinggi diperlukan untuk aplikasi otomotif atau peralatan.
