Toetra sy tombony
Ny bolt hexagon dia karazana fametahana izay natao miaraka amin'ny loha enina lamosina sy amboara misy kofehy.DIN 931 dia fenitra ara-teknika izay mamaritra ny fepetra takian'ny famokarana ho an'ny bolt hexagon.Ireo bolt ireo dia matetika ampiasaina amin'ny fampiharana indostrialy sy mekanika isan-karazany noho ny tanjany, ny faharetany ary ny fahaizany.
Ny iray amin'ireo singa manan-danja amin'ny bolt hexagon noforonina ho an'ny DIN 931 dia ny ampahany amin'ny kofehy.Tsy toy ny bolt feno kofehy, izay manana kofehy mamakivaky ny halavan'ny tsorakazo manontolo, ny bolt hexagon dia manana kofehy amin'ny ampahany amin'ny halavany ihany.Ity famolavolana ity dia mamela ny bolt ho voafatotra tsara amin'ny toerany raha mbola manome fahafahana ampy ho an'ny singa mihetsika rehefa ilaina izany.
Ny lafiny manan-danja iray hafa amin'ny bolt hexagon dia ny lohany enina.Ity endrika ity dia manome tombony maro noho ireo karazana bolt hafa.Voalohany, ny endrika hexagonal dia mamela ny fanamafisana sy famahana mora kokoa amin'ny fanerena na socket.Faharoa, ny faritra lehibe kokoa amin'ny loha dia mizara ny herin'ny fihenjanana amin'ny faritra midadasika kokoa, mampihena ny mety ho fahasimbana na deformation.
Ny bolt hexagon noforonina ho an'ny DIN 931 dia misy amin'ny habe sy fitaovana isan-karazany, ka mahatonga azy ireo ho mety amin'ny fampiharana maro be.Matetika izy ireo no ampiasaina amin'ny fanamboarana, fiara ary milina indostrialy, ary koa amin'ny tetikasa tokantrano sy DIY.Ny fampifangaroana ny tanjany, ny faharetany ary ny fanamorana ny fampiasana dia mahatonga ny bolt hexagon ho singa tena ilaina amin'ny karazana milina sy fitaovana maro.
Raha fintinina, ny bolt hexagon noforonina ho an'ny DIN 931 dia natao hanomezana vahaolana azo antoka sy azo antoka ho an'ny fampiharana isan-karazany.Manome tombony isan-karazany ny tsorakazo misy kofehy vita amin'ny ampahany sy ny lohany enina, ao anatin'izany ny fanamorana ny fampiasana, ny fitomboan'ny tanjaka sy ny faharetana ary ny fahaiza-manao.Ireo bolt dia ampahany manan-danja amin'ny karazana milina sy fitaovana maro, ary ny lazany dia porofon'ny kalitao sy ny fahombiazany.
