Feartan agus buannachdan
Tha DIN 6921 na sheòrsa de bolt flange hex a thathas a’ cleachdadh gu cumanta ann an tagraidhean gnìomhachais agus togail.Tha flange aig a’ bholt seo a bhios ag obair mar inneal-nigheadaireachd togte agus a chuidicheas le bhith a ’cuairteachadh an luchd thairis air farsaingeachd uachdar nas fharsainge.Tha cumadh sia-thaobhach aig ceann a’ bholt agus tha e furasta a theannachadh le bhith a’ cleachdadh sreang no socaid.
Tha am bolt seo air a chleachdadh gu farsaing ann an innealan, gnìomhachasan chàraichean, agus ann an togail, air sgàth cho làidir ‘s a tha e agus seasmhachd.Tha e air a dhèanamh de stuthan àrd-inbhe leithid stàilinn gun staoin, titanium, agus stàilinn gualain, a bheir seachad dìon fad-ùine an aghaidh caitheamh, creimeadh agus meirge.
Tha boltaichean DIN 6921 air an dèanamh a rèir fulangas teann agus tha iad fo smachd ceumannan smachd càileachd teann gus dèanamh cinnteach gu bheil iad a’ coinneachadh ris na h-ìrean càileachd is coileanaidh as àirde.Tha na boltaichean sin rim faighinn ann an raon de mheudan, faid, agus crìochnachaidhean gus freagairt air diofar thagraidhean agus riatanasan.
A bharrachd air an sin, tha boltaichean DIN 6921 a’ cumail ri inbhean gnìomhachais teann, a’ toirt a-steach inbhean DIN (Deutsches Institut für Normung) agus ISO (Buidheann Inbhean Eadar-nàiseanta).Thathas cuideachd a’ dèanamh deuchainn orra airson an cruas, an neart tensile, agus an cruinneas meudachd mus tèid an leigeil ma sgaoil airson an reic.Tha na factaran sin uile a’ cur ri càileachd barraichte agus coileanadh earbsach bolt DIN 6921.
Gu h-iomlan, tha am bolt DIN 6921 na fhuasgladh ceangail sùbailte is làidir a thathas a ’cleachdadh ann an iomadh gnìomhachas eadar-dhealaichte.Tha e air a dhealbhadh gus cumhachd grèim sàr-mhath a thoirt seachad, strì an aghaidh caitheamh is deòir, agus furasta a chuir a-steach.Tha an togail de chàileachd àrd agus cumail gu teann ri inbhean gnìomhachais ga fhàgail na phrìomh roghainn dha innleadairean, luchd-dealbhaidh agus proifeiseantaich togail air feadh an t-saoghail.
