Inkcazo yeenkcukacha

I-DIN7991 countersunk hexagon socket screw, intloko i-conical, umbindi yi-hexagon ehlaziyiweyo, intloko ye-screw ingafakwa kwindawo yokunyuka emva kofakelo, umphezulu ugudile kwaye mhle. Intloko ye-countersunk hexagon socket screw inokufakwa kwicandelo, kwaye inokufaka i-torque enkulu, kwaye amandla okudibanisa aphezulu. Ingathatha indawo yebholiti yesokethi enehexagon. Isetyenziswa rhoqo kwisakhiwo se-compact, imbonakalo egudileyo yokudibanisa. I-DIN7991 ihexagon socket countersunk head screw yireferensi yomgangatho waseJamani DIN7991-1986, echaza inkcazo yentambo esuka kwi-M3 --M24 ISO metric thread, ibakala lemveliso A hexagon socket countersunk head screw.

DIN7991 ihexagon socket countersunk izikrufu zentloko ziyafumaneka kwikhabhoni yentsimbi kunye nentsimbi engatyiwa. Amabakala okusebenza kwe-carbon steel hexagon socket countersunk head screws yi-8.8, 10.9, 12.9, umgangatho ungabhekisela kwi-GB3098.1. Izixhobo zentsimbi yeCarbon zifuna unyango olungaphezulu, okuqhelekileyo yi-oxidation, i-electroplating, efana nesidingo somnye umphezulu wokutyabeka okanye unyango olungaphezulu, kunokuxoxwa. Izikrufu zentsimbi ye-hexagon ye-hexagon ye-countersunk head screws edla ngokusetyenziswa emarikeni zenziwe nge-SUS304 kunye ne-SUS316, ukuxhathisa kwentsimbi engatyiwayo kunye nokuxhathisa ubushushu komelele. I-SUS304 isantya esiphakathi sokuqina komsebenzi, esilungele umsebenzi obandayo ngokubanzi kunye nokwelula; I-CORROSION RESISTANCE YE-SUS316 INGCONO KUNOKUNO-304. IFANELE KAKHULU KUNYE nemithombo yeendaba zaseLwandle kunye neekhemikhali. Inokumelana ne-corrosion engcono kunye nokuxhathisa ukubola komngxuma.

I-hexagon socket screws ihlulwe ibe yi-cylindrical head hexagon bolts ngokwentloko, esetyenziswa ngokuqhelekileyo, kwaye ineentlobo ezininzi, ngokwezinto eziphathekayo, kukho isinyithi, oko kukuthi, i-carbon steel kunye nensimbi engenasici. Iibholiti ze-hex zensimbi ezingenasici zinentsimbi engatyiwayo engama-304 kunye ne-202 kunye nokunye. Ibholiti yesokethi ye-hex engqukuva, oku kukwabizwa ngokuba yi-pan yentloko ye-hex socket bolt. I-countersunk intloko ye-hex socket bolt, intloko yintloko ethe tyaba, ngaphakathi yi-hex socket. Kukho uhlobo lomgangatho wesizwe okhethekileyo ngakumbi, obizwa ngokuba yihexagon bolt engenantloko. Yeyiphi into esihlala siyibiza ngokuba sisikrufu semitha, isikrufu sokuhlawula, isikrufu esiseti. La magama aqhelekileyo kwiibholiti ze-hex ezingenantloko, kodwa zonke zithetha into enye. Ewe kunjalo, kukwakho neebholiti ezinentloko eneentyatyambo engaphakathi enehexagon. Olu setyenziso luncinci, imarike nayo inzima ukuyibona. I-hexagon socket screw nangona iindidi zemigangatho yesizwe nazo zininzi, kodwa ngokusisiseko ezinye ezikhethekileyo, ngokusisiseko bambalwa abantu abaya kusebenzisa emarikeni. Isetyenziswe ngaphezulu okanye inani le-cylindrical head hex socket screws, ekwaziwa njenge-cylindrical head hex socket screws.
