| Ainm Táirge | Boltaí Graí Cruach Dhosmálta |
| Ábhar | Déanta as cruach dhosmálta 304/316, tá friotaíocht ceimiceach maith ag na scriúnna seo agus féadfaidh siad a bheith beagán maighnéadach. Tugtar cruach dhosmálta A2/A4 orthu freisin. |
| Cineál Ceann | Gan cheann. |
| Iarratas | Daingnigh teanntáin agus daingneáin socraithe le do bhord meaisín, nó cruinnigh meaisíní troma, cosúil le gléasanna innill. Feidhmíonn na studs seo mar phíolóta agus páirteanna á nascadh ós rud é go bhfuil siad gan cheann, rud a éascaíonn suiteáil. Murab ionann agus bolt, a bhfuil ceann acu, ligeann siad duit codanna a rochtain ó cheachtar ceann, ach éilíonn siad cnónna chun an chuid a shealbhú. Péireáil iad le sliotán T nó le cnó flanged agus iad ag daingniú chuig bord meaisín. Nó, cuir cnó ar aghaidh roimh do chuid chun oibriú mar shnámhphointe, rud a ligeann duit airde do chuid a choigeartú. Tá an lár neamhshnáithithe úsáideach le haghaidh greim agus coigeartú. Tugtar studs dúbailte ar a dtugtar freisin. |
| Caighdeán | Comhlíonann siad go léir sonraíochtaí ASME B18.31.3 nó DIN 939 maidir le caighdeáin tríthoiseach. |
