Kune marudzi akawanda emasikiru, imwe inonzi hexagon socket screws. Paunenge uchitenga, mutengesi achakubvunzawo kuti ndeupi rudzi rwekusarudza. Pakutanga, kune akawanda maratidziro ehexagon socket screws.

Kune akati wandei marudzi ehexagon socket screws
1. Pane imwe type yehexagon socket screw inonzi pan head. Mushure mekunge screw yaiswa, musoro wayo unobuda pamusoro, izvo zvinoita kuti zvive nyore kuputira screw gare gare. Ichi chigadzirwa chinogona kuonekwa pane zvimwe midziyo yemumba.

2.Kune countersunk head hexagon socket screws, izvo zvinoreva kuti hazvizobudi kubva kumusoro mushure mekuputika, uye hazvizokanganisa chitarisiko. Nekudaro, kana paine dambudziko rakaoma kukora kana screwing, screw haigone kutangwa.

3.Kunewo cylindrical head hexagon socket screws, iyo yakafanana nemhando yechipiri yezviputi. Iwo ane simba uye anoda wrench yeanoenderana yakatarwa kuti abvise screws. Kazhinji kutaura, ivo vanoshandiswa pamaturusi emuchina.

Iyo screw ine ngura uye haigone kusunungurwa, ndoita sei?
Muupenyu, shamwari dzakawanda dzakasangana nezvinetso zvakafanana. Kana mascrews aita ngura, zvisinei kuti isimba rakawanda sei rinoshandiswa, haagone kusunungurwa. Nekuti iyo screw inooneswa kumhepo, kana iyo yakatenderedza nharaunda ine hunyoro, mushure menguva refu, inowanzoitika kuita ngura. Muchokwadi, usashandise brute force, iwe unofanirwa kugona hunyanzvi hwekupusha.

Tora iyo yekutanga, dzvanya screw ine corroded ne wrench, uye bata mubato zvishoma, nekuti kana chikamu chine ngura chakasununguka, chinogona kuburitswa gare gare.

Kana iyo ichiri kusashanda mushure mekutapa, unogona kudonhedza mafuta mashoma, wozoitenderedza zvinyoro nyoro nechipanera nguva shoma. Kana usina mafuta kumba, unogona kushandisa Coke nekuti inobvisa ngura.
