The first jaw member (410) includes a first tissue engaging surface (411) and the second jaw member (420) supports a fastener cartridge (420a). The fastener cartridge (420a) includes a second tissue engaging surface (423a) that defines fastener retaining slots (423b) that support fasteners. The drive beam (500) includes a retention foot (520) formed of a first material. The retention foot (520) defines a threaded bore (522) that supports a threaded insert (530) formed of a second material. The threaded drive screw (424) is threadably engaged with the threaded insert (530) and is rotatable to distally advance the drive beam (500) along the threaded drive screw (424) to fire and form the fasteners.2/10 C>C 4 C14u / =O CC.0 VC1
