Tuairisgeul toraidh

[270]

Boltaichean cinn Hexagon Dubh:Tha ceann sia-thaobhach anns na boltaichean sin agus tha iad còmhdaichte le crìoch dubh, mar as trice air an coileanadh tro phròiseasan leithid còmhdach dubh ocsaid no plating sinc dubh.

Frith-aghaidh creimeadh:Chan e a-mhàin gu bheil an còmhdach dubh a’ toirt tarraingeas eireachdail ach bidh e cuideachd a’ cur ri strì nam boltaichean an aghaidh creimeadh, gan dèanamh freagarrach airson àrainneachdan a-muigh agus àrd taiseachd.

Ceangal seasmhach:Bidh boltaichean ceann hexagon a’ tabhann fuasgladh ceangail làidir is seasmhach, comasach air seasamh ri luchdan is cuideaman àrda ann an diofar thagraidhean.

Raon farsaing de mheudan:Ri fhaighinn ann an raon farsaing de mheudan agus raointean snàithle, faodaidh boltaichean ceann sia-cheàrnach dubh coinneachadh ri diofar riatanasan airson a bhith a’ ceangal diofar stuthan agus cho-phàirtean.

Iarrtasan ioma-chruthach:Bidh na boltaichean sin a’ lorg thagraidhean ann an càraichean, togail, innealan agus gnìomhachasan eile far a bheil feum air measgachadh de neart, strì an aghaidh creimeadh, agus bòidhchead.

Meudan meatrach agus òirleach:Tha boltaichean ceann sia-cheàrnach dubh rim faighinn an dà chuid ann am meudan meatrach agus òirleach, a’ dèanamh cinnteach gu bheil iad co-chòrdalachd le diofar shiostaman ceangail agus roghainnean.
