Amaxabiso etorque axhomekeke kwidayamitha yesikrufu, isandi somsonto, i-coefficient yokukhuhlana, kunye nokulayisha kwangaphambili okufunekayo. Iitheyibhile eziqhelekileyo ezibonelelwa yimibutho efana neVDI 2230 zinika izikhokelo. Nangona kunjalo, kwizicelo ezibalulekileyo, kukulungele ukubonisana nephepha ledatha lomenzi othile, njengoko ukuhluka kwi-coating kunye ne-lubrication kunokutshintsha kakhulu ubudlelwane be-torque-tension. Ungaze uqikelele amaxabiso etorque kuqhagamshelo lwesakhiwo.

Ukuqukumbela kunye neNgcebiso yokuFumana iQhinga

Ibango le I-10.9 yebakala le-counterhead hexagon socket head cap izikrufu iyaqhubeka nokunyuka njengoko amashishini etyhala ukusebenza okuphezulu kunye nokuthembeka kwiindibano zabo zomatshini. Njengoko sisondela ku-2026, imarike iya kuthanda ababoneleli abanokubonisa ukuzinikela okungagungqiyo kumgangatho, ukulandeleka, kunye neendlela ezizinzileyo zokwenziwa kwemveliso. Umahluko wamaxabiso phakathi koncedo oluthe ngqo kumzi-mveliso kunye namajelo osasazo usabalulekile, nto leyo eyenza uthethathethwano oluthe ngqo nabavelisi abaqinisekisiweyo lube yimfuneko yesicwangciso-qhinga kubathengi abajonga iindleko.

Kumaqela obunjineli, ukhetho lwee-fasteners ze-10.9 kufuneka luqhutywe ngokuqonda ngokucacileyo iimfuno zomthwalo kunye neemeko zokusingqongileyo. Ngelixa iindleko zokuqala zinokuba phezulu kunezinye iindlela zodidi olusezantsi, ubomi obude kunye nomda wokhuseleko abawunikezelayo zibonelela ngexabiso elikhulu lexesha elide. Ukuqinisekisa ufakelo olululo kunye nokubambelela kwiishedyuli zolondolozo kuya kwandisa umjikelo wobomi bala macandelo abalulekileyo.

Iingcali zokuthengwa kwempahla ziyacetyiswa ukuba zibeke phambili ababoneleli ngezatifikethi ze-ISO kunye nerekhodi eqinisekisiweyo kwimveliso ye-fastener ephezulu. Ukucela iibhetshi zeesampulu zovavanyo oluzimeleyo phambi kokwenza iiodolo ezinkulu linyathelo elilumkileyo lokuqinisekisa amabango omgangatho. Ngokujolisa ekugqweseni kobugcisa kunye nokungafihlisi kwekhonkco lokubonelela, amashishini anokukhusela izisombululo zentsebenzo ephezulu efunekayo ukuze ziphumelele kukhuphiswano lwelizwe lowama-2026 nangaphaya.
