Kodi mumadziwa kuti woyamba kudziwika analemba ntchitozomangirazinachitika m’nthawi ya Agiriki akale?Anagwiritsa ntchito zomangira m'zida zopondera azitona ndi mphesa, umboni wanzeru zawo komanso luso lawo.Kuyambira nthawi imeneyo, zomangira zasintha kukhala chimodzi mwazinthu zofunika kwambiri komanso zomwe zimagwiritsidwa ntchito kwambiri masiku ano.
Fastener hardware yasintha kwambiri pakapita nthawi, ndi mitundu yambiri yamawonekedwe, makulidwe, masitayilo, ndi zida zomwe zikupezeka pamsika.Mukasankha chomangira cha pulogalamu yanu, chimodzi mwazinthu zofunika kwambiri kuziganizira ndi mtundu wamutu womwe screw idzakhala nawo.
Mutu wa screw ndi wofunikira pazifukwa zosiyanasiyana.Zimasankha njira yoyendetsera galimoto kapena kutembenuza screw, komanso zimakhudza kukongola ndi ntchito ya chinthu chomaliza.Chifukwa chake, kumvetsetsa mitundu yosiyanasiyana ya mitu ya screw ndi maubwino ake ndikofunikira kuti mupange chisankho mwanzeru.
Mtundu umodzi womwe umagwiritsidwa ntchito kwambiri wa screw mutu ndi mutu wa Phillips.Yopangidwa m'zaka za m'ma 1930 ndi Henry F. Phillips, imakhala ndi malo opumira omwe amalola Phillips screwdriver kuti agwire motetezeka.Mapangidwe ake amathandizira kutumiza kwa torque kwabwino, kuchepetsa mwayi wotsetsereka ndikuwonetsetsa kulumikizana kodalirika.Mutu wa Phillips wakhala ukupezeka paliponse m'mafakitale ambiri ndi ntchito zapakhomo.
Mutu wina wotchuka wa screw ndi flathead, yomwe imadziwikanso kuti slotted screw.Imakhala ndi slot yowongoka pamwamba, ndikupangitsa kuti iyendetsedwe pogwiritsa ntchito screwdriver flathead.Ngakhale sizingagwire mofanana ndi mitu ina yowononga, imagwiritsidwabe ntchito kwambiri popanga matabwa, kusonkhanitsa mipando, ndi ntchito zina zachikhalidwe.Kuphweka kwa flathead ndi kugulidwa kumapangitsa kuti apitirize kutchuka.
Posachedwapa, mutu wa Torx watchuka kwambiri.Yopangidwa ndi kampani ya Camcar Textron mu 1967, imakhala ndi malo opumira ngati nyenyezi.Mapangidwe awa amathandizira kufalikira kwa torque, kuchepetsa chiopsezo chovula kapena kutulutsa.Mutu wa Torx umagwiritsidwa ntchito nthawi zambiri m'mafakitale omwe amafunikira ma torque olondola komanso apamwamba, monga magalimoto, zamagetsi, ndi ndege.
Pazinthu zomwe kukongola kuli kofunikira, socket head cap screw imapereka mawonekedwe owoneka bwino komanso owoneka bwino.Ili ndi mutu wa cylindrical wokhala ndi socket yamkati ya hex, yomwe imalola kuti iyendetsedwe pogwiritsa ntchito wrench ya Allen kapena kiyi ya hex.Socket head cap screw imagwiritsidwa ntchito kwambiri pamakina, magalimoto, komanso mipando yapamwamba, komwe kumafunikira mawonekedwe oyera komanso owoneka bwino.
Kupatula zosankha zotchukazi, palinso mitundu ina yambiri yamutu wa screw yomwe ilipo, iliyonse ili ndi zabwino zake.Mwachitsanzo, ma square drive, Pozidriv, ndi mitu ya hexagonal amagwiritsidwa ntchito m'mafakitale apadera kapena ntchito zapadera.
Pomaliza, kusankha chomangira choyenera cha pulogalamu yanu kumaphatikizapo kuganizira zinthu zosiyanasiyana, monga kukula, zinthu, ndi kalembedwe.Komabe, mtundu wamutu womwe screw idzakhala nayo ndiyofunikira kwambiri, chifukwa imatsimikizira momwe galimoto imayendera ndipo imatha kukhudza magwiridwe antchito ndi mawonekedwe a chinthu chomaliza.Kaya mumasankha mutu woyeserera komanso wowona wa Phillips, mutu wamba wamba, kapena kulondola kwa mutu wa Torx, kumvetsetsa mitundu yosiyanasiyana ya mitu ya screw kuwonetsetsa kuti mumasankha mwanzeru pankhani yosankha chomangira choyenera pazosowa zanu.
