FAQ
Q: Ngikhetha kanjani i-DIN 7991 hex socket screw size?
IMP: Khetha ububanzi nobude ngokusekelwe kugqinsi lwempahla, isidingo somthwalo, futhi uqinisekise ukufakwa kwe-countersunk eshaywayo.
Q: Yiziphi izinto ezilungele izikulufu ze-DIN 7991 countersunk ezindaweni ezigqwalile?
A: Insimbi engagqwali amamaki A2-70, A4-70, A4-80 noma camera steel (zinc plated / black oxide) ukumelana ukugqwala.
Q: Ingabe i-DIN 7991 hex socket countersunk screws ingasetshenziswa emibuthanweni ye-aluminium?
IMPENDULO: Yebo, kodwa ukulawulwa kwetorque kanye nokujula kosinki okulungile kuyadingeka ukuze kuvinjelwe ukukhumula intambo nokulimala kwendawo.
Q: Yini eqinisekisa ukusebenza kwetorque okuzinzile ku-DIN 7991 socket head countersunk screws?
A: I-ISO efanele-ifaniswe nosayizi wokhiye we-hex kanye nohlelo lokusebenza lwetorque elawulwayo kunciphisa ukuzungeza futhi kuthuthukise ukuthembeka kokuqiniswa.
Q: Yini okufanele ihlolwe lapho kutholwa izinsimbi ze-DIN 7991?
A: Qinisekisa ibanga (8.8 / 10.9 / 12.9), amandla aqinile, ikhwalithi yokunamathela, nokuthobelana nezindinganiso ze-DIN 7991 / ISO 10642.
