Ciri-ciri dan manfaat
Flange Bolt Din 6921 Cl 8.8 ialah pengikat berkekuatan tinggi yang biasa digunakan dalam aplikasi tugas berat.Ia adalah sejenis bolt bebibir yang direka bentuk dengan bebibir seperti mesin basuh di pangkalan, yang memberikan sokongan tambahan dan menghalang bolt daripada longgar akibat getaran atau tork.Bolt mempunyai kepala heksagon yang membolehkan pemasangan dan penyingkiran mudah menggunakan sepana atau playar.
Dihasilkan dengan mematuhi piawaian DIN 6921, bolt bebibir ini memenuhi keperluan khusus untuk saiz benang, panjang dan padang, serta sifat bahan dan mekanikal.Ia diperbuat daripada keluli karbon sederhana yang dialoi dengan unsur-unsur seperti kromium, molibdenum, dan vanadium, yang meningkatkan kekuatan dan ketahanannya.Bolt juga disalut dengan lapisan pelindung, seperti penyaduran zink atau galvanisasi, yang menghalang pembentukan kakisan dan karat.
Bolt bebibir ini mempunyai penarafan Kelas 8.8, menunjukkan kekuatan tegangannya sekurang-kurangnya 800 N/mm2 dan kekuatan hasil sekurang-kurangnya 640 N/mm2.Ini menjadikannya sesuai untuk digunakan dalam aplikasi yang memerlukan daya pengapit yang tinggi dan rintangan kepada keletihan, hentaman dan daya sisi.Ia biasanya digunakan dalam aplikasi automotif, pembinaan, mesin dan peralatan industri.
Panjang bolt berbeza-beza bergantung pada keperluan aplikasi khusus, antara 10 mm hingga 100 mm atau lebih.Saiz benang berjulat dari M6 hingga M30 atau lebih besar, dengan jenis pic yang berbeza tersedia seperti halus, kasar dan lebih kasar.Kepala heksagon mungkin bebibir atau chamfer dan mungkin juga mempunyai ceruk atau tanda untuk menunjukkan pengilang atau gred.
Secara keseluruhan, Flange Bolt Din 6921 Cl 8.8 ialah penyelesaian pengikat yang boleh dipercayai dan tahan lama yang memberikan kekuatan, kestabilan dan rintangan kakisan yang sangat baik.Reka bentuk berkualiti tinggi dan pembuatan ketepatan memastikan prestasi optimum dan keselamatan dalam pelbagai aplikasi tugas berat.
