Yintoni eyenza i-DIN 7991 izikrweqe ezikhethekileyo

Izikrufu ze-DIN 7991 zichazwa yindibaniselwano yeempawu ezilungiselelwe ukulawulwa,{1}}ukuqiniselwa okuchanekileyo:

I-countersunk intloko ethe tyabaehlala egungxulwayo phakathi kweesinki zombiweyo

I-hex drive yangaphakathiukwenzela ukubandakanyeka kwesixhobo esikhuselekileyo kunye netorque elawulwayo

I-shank efanayo kunye neprofayili yomsontoukusebenza okuphindaphindiweyo

Intsimbi okanye izinto ezingenasicikuxhomekeke kwimekobume

Olu luyilo lunciphisa uphazamiseko namanye amalungu kwaye lucuthe ukukrwela okanye ukurhwebesha kwindawo evalelekileyo{0}}ekudityanisiweyo.

Usetyenziso oluQhelekileyo kunye nezicelo

I-hex socket flat head screws ezihambelana nomgangatho we-DIN 7991 ziqhele ukufunyanwa kwi:

Indibano yezixhobo zoshishino

Iindawo zemoto kunye nezixhobo

Iirobhothi kunye neenkqubo ezizenzekelayo

Iindawo ezivaliweyo zombane

Iindibano zentsimbi zeshiti

Oomatshini abachanekileyo apho kufuneka iindawo ezigungxulwayo

Ngenxa yenkangeleko yabo ecocekileyo kunye ne-interface ekhuselekileyo ye-drive, ezi zibophelelo zisetyenziswa rhoqo kwiiprojekthi apho zombini umsebenzi kunye nobuhle bubalulekile.
UKhetho lweMathiriyeli kunye noKhuseleko loMphezulu

Screw Materials

Intsimbi yeCarbon- Iindleko{1}}ezisebenzayo kwaye zomelele

Intsimbi engatyiwa (304 / 316)- Ukumelana nomhlwa okugqwesileyo

Intsimbi yentsimbi- Amandla aphezulu okusingqongileyo okunyanzelisayo

Ukugqitywa kunye neeNgqungquthela

Ukufakwa kweZinc- Ikhusela intsimbi kwiimeko zoshishino jikelele

I-oksidi emnyama- Isiphelo esihonjisiweyo esinokuxhathisa umhlwa

Mechanical Galvanizing- Ukhuseleko lomhlwa olomeleziweyo

UkuGqiba okucacileyo (Kungenazitya)- I-Corrosion ngokwemvelo{1}}iyaxhathisa

Ukukhetha izinto ezifanelekileyo kunye nokwaleka kuxhomekeke kwizinto ezifana nokufuma, ukuvezwa kweekhemikhali, kunye neemfuno zomthwalo.
