Flangeless inflators include a body comprising a base member and a diffuser member coupled together, where the body is devoid of a lateral inflator-coupling flange. At least one fastener is coupled to the base member of the body. In an inflatable airbag system, the flangeless inflator is coupled to an airbag cushion, as well as to a steering wheel armature. In forming flangeless inflators, a body is formed that is devoid of the lateral inflator-coupling flange, and at least one fastener is attached to the body.
