Is ceanglóir é bolt heicseagánach flange a úsáidtear chun comhpháirteanna a nascadh, agus áirítear ar a phríomhfheidhmeanna:
Ceangal cobhsaí a sholáthar: Tá fórsa géarú mór ag an bolt heicseagánach flange, is féidir leis an flange agus na comhpháirteanna nasctha a nascadh go daingean, ag cinntiú cobhsaíocht an cheangail.
1. Tarchur bpower: Ní hamháin go bhféadfaidh sé fórsa cheangail a tharchur, ach freisin an chumhacht a theastaíonn ó mheaisíní, trealamh, etc.
2. A chinntiú ina saothraítear rónta: Is féidir le húsáid boltaí heicseagánacha flange an nasc a leithlisiú ó na meáin sheachtracha agus a chinntiú go bhfuil an gléas ina saothraítear rónta.
3. In ann fórsa réamhlódála níos airde a sheasamh: Toisc go bhfuil a "cóimheas idir an limistéar tacaíochta agus an limistéar struis" níos airde ná an gnáth-bolt, is féidir le boltaí heicseagánacha flange fórsa réamh-lódála níos airde a sheasamh agus feidhmíocht frithscaoilte níos fearr a bheith acu.
