ASTM A194
Spesifikasi ASTM A194 nyakup kacang karbon, campuran lan baja tahan karat sing digunakake ing layanan tekanan dhuwur lan / utawa suhu dhuwur. Kajaba kasebut, American National Standard Heavy Hex Series (ANSI B 18.2.2) bakal digunakake. Kacang nganti lan kalebu ukuran nominal 1 inci kudu pas UNC Series Kelas 2B. Kacang sing ukurane nominal luwih saka 1 inci kudu cocog karo UNC Series Class 2B utawa 8 UN Series Class 2B fit. Kacang 2H kelas ASTM A194 kanthi kekuatan dhuwur umume ana ing pasar lan asring diganti karo kacang DH kelas ASTM A563 amarga kasedhiyan kacang DH sing winates ing diameter lan finish tartamtu.

Cathetan: 1. Tandha sing ditampilake kanggo kabeh biji kacang A194 yaiku kanggo kacang palsu sing digawe adhem lan panas. Nalika kacang dimesin saka stok bar, kacang kasebut kudu ditandhani kanthi huruf 'B'. Huruf H lan M nuduhake kacang sing diolah panas. 2. Properties ditampilake sing saka coarse lan 8-pitch thread heavy kacang hex. 3. angka atose sing Brinell atose. 4. Kacang-kacangan sing diobati kanthi solusi karbida mbutuhake huruf tambahan A - 8A utawa 8MA. 5. Kabeh kacang kudu diwenehi tandha identifikasi pabrikan. Kacang-kacangan kudu ditandhani kanthi cetha ing siji pasuryan kanggo nunjukake kelas lan proses pabrikan. Nandhani flat wrench utawa permukaan bantalan ora diidini kajaba disepakati antarane pabrikan lan panuku. Kacang sing dilapisi seng duwe tanda bintang (*) sing ditandhani sawise simbol kelas. Kacang-kacangan sing dilapisi kadmium kudu diwenehi tandha plus (+) sawise simbol kelas. 6. Gelar liyane sing kurang umum ana, nanging ora ana ing kene. Standar Pengikat Inch. 7 ed.
