A jaw member for use with a surgical instrument includes a support base, a jaw liner, and a jaw overmold. The support base has a proximal portion configured to be pivotably coupled to a surgical instrument, and a distal portion. The support base defines a channel that extends longitudinally between the proximal and distal portions and an aperture disposed in communication with the channel. The jaw liner includes an elongate body configured for receipt in the channel of the support base, and a projection extending from the elongate body and configured for receipt in the aperture of the support base. The jaw overmold overlaps at least a portion of the support base and the jaw liner to fix the jaw liner to the support base.
