DIN7991 countersunk hexagon socket screw, o le ulu o le conical, o le ogatotonu o se hexagon faʻamama, o le ulu faʻasili e mafai ona faʻapipiʻiina i luga o le faʻapipiʻiina pe a uma ona faʻapipiʻi, e lamolemole ma matagofie. E mafai ona fa'apipi'i i totonu o le vaega le ulu o le sikulima socket hexagon countersunk, ma e mafai ona fa'aogaina le malosi tele, ma e maualuga atu le malosi o feso'ota'iga. E mafai ona sui ai le fa'amau socket hexagon. E masani ona faʻaaogaina i le fausaga o foliga faʻapitoa, lamolemole o le sooga. DIN7991 hexagon socket countersunk head screw o se fa'asino i le tulaga Siamani DIN7991-1986, o lo'o fa'amaoti mai ai le filo fa'amatalaga mai M3 -- M24 ISO metric filo, oloa togi A hexagon socket countersunk ulu siku.

DIN7991 hexagon socket countersunk ulu fa'asili o lo'o maua i le carbon steel ma stainless steel. O togi fa'atinoga o fa'ailoga fa'ailoga fa'ato'a fa'asolo fa'aono fa'a kaponi e 8.8, 10.9, 12.9, o le fa'ata'ita'iga e mafai ona fa'asino ile GB3098.1. O mea uamea carbon e masani ona manaʻomia togafitiga i luga, masani o le faʻamaʻiina, eletise, e pei o le manaʻomia mo isi faʻapipiʻi luga poʻo togafitiga luga, e mafai foi ona faʻatalanoa. Uamea uamea uamea fa'amau fa'amau fa'amau fa'ailoga ulu e masani ona fa'aogaina i luga o le maketi e faia i le SUS304 ma le SUS316, e malosi le fa'a'ele'ele mea uamea ma le vevela. SUS304 fua faatatau fa'amalosi galuega, talafeagai mo galuega malulu lautele ma fa'aloloa; O LE TETEE O LE CORROSION O SUS316 E SILI AI LE 304. E FA'AMATALAGA FA'AMATALAGA MO ala o le gataifale ma vaila'au. E sili atu le corrosion teteʻe ma pu.

Ua vaevaeina fao sikulima hexagon i totonu o le ulu o le hexagon socket bolts e tusa ai ma le ulu, lea e masani ona faʻaaogaina, ma e tele foʻi ituaiga, e tusa ai ma meafaitino, o loʻo i ai uʻamea, o lona uiga, carbon steel ma stainless steel. E iai fo'i fa'alava u'amea u'amea uamea u'amea 304 ma 202 ma isi mea. Semi - lapotopoto ulu hex socket bolt, lea ua ta'ua foi pan head hex socket bolt. Countersunk head hex socket bolt, ulu o le ulu mafolafola, totonu o le hex socket. O loʻo i ai se ituaiga o tulaga faʻale-atunuu e sili atu ona faʻapitoa, e taʻua o le headless hexagon bolt. O le mea lea e masani ona ta'ua o le sikulima mita, o le sikulima totogi, o le sikulima seti. O faaupuga masani ia mo fa'amau hex e leai ni ulu, ae tutusa uma uiga. Ioe, o lo'o iai fo'i fa'amau e fuga i totonu ulu hexagon. O lenei faʻaoga e itiiti, o le maketi e matua faigata lava ona vaʻaia. Hexagon socket screw e ui o le tele o tulaga fa'ale-atunu'u e tele atu, ae o nisi mea e sili atu ona fa'apitoa, e to'aitiiti tagata o le a alu e fa'aoga i le maketi. Fa'aaoga le tele po'o le numera o fa'asili fa'alava ulu hex, fa'aigoa fo'i fa'asili fa'alava ulu hex.
