I-Black grade 12.9 DIN 912 Cylindrical Socket cap screw/Allen bolt

Izikrufu zentloko zesokhethi zisetyenziselwa usetyenziso olunesithuba esincinci. Zineempawu zokutsala intloko ezisicaba kunye nezangaphakathi (ikakhulu i-hexagon socket) ezivumela ukuba zisetyenziswe kwiindawo apho izibophelelo ezitsalwe ngaphandle zingafunwayo.

Zisetyenziswa kwizicelo ezibalulekileyo zezithuthi, kwizixhobo zoomatshini, kwizixhobo kunye needayi, kwizixhobo zokuhambisa umhlaba kunye nezokwemba, kunye noluhlu olubanzi lwezicelo zobunjineli. Ezona zizathu zibalulekileyo zokusetyenziswa kakhulu kwezikrufu zentloko yesokhethi kushishino kukhuseleko, ukuthembeka kunye noqoqosho.

Uthotho lwe-1936 kunye nothotho lwe-1960
Eli gama lisetyenziswa ngokubanzi eMelika. Ulwakhiwo lokuqala lwezikrufu ze-socket head cap aluzange lugcine ubudlelwane obuhambelanayo phakathi kobubanzi be-shank obuqhelekileyo, ububanzi bentloko, kunye nobukhulu be-socket kulo lonke uluhlu lobukhulu obufumanekayo. Oku kunciphisa amandla okusebenza kwezinye iisayizi.

Kwiminyaka yoo-1950, omnye umenzi wezikrufu zesokhethi eMelika wenza uphando olunzulu ukuze aphucule ukusebenza ngokusekelwe kwijiyometri, amandla ezinto zokubopha, kunye nokusetyenziswa kwazo. Ezi zifundo zaphumela kubudlelwane obufanayo kuluhlu lobukhulu.

Ekugqibeleni, olu lwalamano lwamkelwa njengemigangatho yoshishino kwaye unyaka wokwamkelwa - 1960 - wamkelwa ukuchonga uyilo oluphuculweyo. Igama elithi 1936-Series lakhethwa ukuchonga isitayile esidala semfuno yokutshintshwa.

I-Socket kunye ne-Allied zithwala uluhlu olubanzi lwee-Socket Cap Screws zika-1936 kunye no-1960 apho kufuneka khona ubungakanani obungaqhelekanga nobuthile kwisicelo esithile.

I-Socket kunye ne-Allied zinokwenza ii-Socket Cap Screws kuluhlu olubanzi lweentsimbi ze-alloy kuquka iintsimbi ze-stainless ezingaqhelekanga kunye neentsimbi ezityheli.

IINZUZO ZEZIKRWEKI ZEZIQHOBO ZE-SOCKET HEAD
- Xa kuthelekiswa neziqhoboshi eziqhelekileyo, izikrufu zesokhethi ezimbalwa ezinobukhulu obufanayo zinokufikelela kumandla afanayo okubamba kwijoyinti.

- Njengoko kufuneka izikrufu ezimbalwa kumsebenzi othile, kufuneka kugqojwe imingxunya embalwa ukuze kugqojwe kwaye kucofwe.

- Kukho ukunciphisa ubunzima njengoko kusetyenziswa izikrufu ezimbalwa.

- Kuya kubakho ukuncitshiswa kobunzima ngenxa yobukhulu obuncinci beendawo eziyinxalenye kuba iintloko zesilinda zezikrufu zesokhethi zifuna indawo encinci kuneentloko zehex kwaye azidingi sithuba songezelelweyo sesikrufu.
