DIN7991 countersunk hexagon socket screw, musoro wakaita conical, yepakati ndeye yakadzoreredzwa hexagon, iyo screw musoro inogona kuisirwa munzvimbo inokwirisa mushure mekuiswa, iyo nzvimbo yakatsetseka uye yakanaka. Musoro we countersunk hexagon socket screw inogona kuisirwa muchikamu, uye inogona kuisa yakakura torque, uye simba rekubatanidza rakakwira. Inogona kutsiva hexagon socket bolt. Kazhinji inoshandiswa muchimiro che compact, kutaridzika kwakanaka kwejoini. DIN7991 hexagon socket countersunk head screw is Ireferensi yeGerman standard DIN7991-1986, iyo inotsanangura iyo tambo yakatarwa kubva kuM3 -- M24 ISO metric shinda, chigadzirwa giredhi A hexagon socket countersunk head screw.

DIN7991 hexagon socket countersunk head screws inowanikwa mucarbon simbi uye simbi isina tsvina. Magiredhi ekuita ecarbon steel hexagon socket countersunk head screws ari 8.8, 10.9, 12.9, chiyero chinogona kureva GB3098.1. Carbon simbi zvinhu zvinowanzoda kurapwa kwepamusoro, zvakajairika ndeye oxidation, electroplating, senge kudiwa kwekumwe kupeta kwepamusoro kana kurapwa kwepamusoro, kunogonawo kutaurirana. Stainless simbi hexagon socket countersunk head screws anowanzo shandiswa pamusika anogadzirwa neSUS304 uye SUS316, simbi isina simbi inodzivirira kuita ngura uye kupisa kupisa kwakasimba. SUS304 yepakati basa kuomesa mwero, yakakodzera kune yakajairika kutonhora basa uye kutambanudza; Iyo CORROSION RESISTANCE YESUS316 IRI KUNANA KUPFUURA IYO YE304. INYANYA KUNYANYA KUKOdzera Marine uye makemikari media. Iyo ine zvirinani kusagadzika kwecorrosion uye gomba corrosion resistance.

Hexagon socket screws yakakamurwa kuita cylindrical head hexagon socket bolts zvinoenderana nemusoro, unowanzo shandiswa, uye inewo marudzi mazhinji, zvinoenderana nechinhu, pane simbi, kureva, kabhoni simbi uye simbi isina tsvina. Stainless simbi hex mabhoti zvakare ane simbi isina tsvina 304 uye 202 uye zvichingodaro zvinhu. Semi - yakatenderera musoro hex socket bolt, izvi zvakare zvakadaidza pan musoro hex socket bolt. Countersunk musoro hex socket bolt, musoro wati sandara musoro, mukati mune hex socket. Kune mhando yemhando yenyika inonyanya kukosha, inonzi isina musoro hexagon bolt. Ndozvatinowanzo kudaidza kuti meter screw, screw yekubhadhara, set screw. Aya ndiwo mazwi akajairika kune asina musoro hex mabhaudhi, asi ese anoreva chinhu chimwe. Ehe, kune zvakare mamwe mabhaudhi ane flowered yemukati hexagon musoro. Kushandisa uku kushoma, musika zvakare wakaoma kuona. Hexagon socket screw kunyangwe iwo akasiyana mazinga emunyika akawedzerawo, asi kunyanya mamwe akakosha, vanhu vashoma vanoenda kunoshandisa pamusika. Inoshandiswa yakawanda kana nhamba yecylindrical head hex socket screws, inozivikanwawo se cylindrical head hex socket screws.
