A fastener installation tool and method for interference fit, said fastener (10) comprising a head and a grasping element, said tool comprising a first body (30) extending along a first main axis and having: —at least one load-reacting surface, of which one also constitutes a surface for the application of a load; —a load transmission surface, and—a housing extending along the first main axis from a first end of said first body, said housing being extended along the first main axis by a drilling extending from said housing as far as a second end of said first body. According to the invention, the load transmission surface is situated at the second end of the first body (30) and extends perpendicular to the first main axis, said load transmission surface being dimensioned to be able to bear simultaneously on the head and on the insert clamp.

A piston supply apparatus includes a piston gripping portion and a piston supply portion. The piston supply portion includes a connecting rod gripping unit gripping the connecting rod of the piston placed in a preparation area, a guide member abutting against a skirt portion of the piston to match an axial direction of the piston with a predetermined specified direction, a moving unit moving the gripping unit from the preparation area to a supply position in air, and a pivoting unit making the gripping unit pivot such that the piston top portion of the piston in a downward state is set in an upward state. The piston supply apparatus further includes a pressing unit pressing the piston top portion of the piston made to pivot to the upward state against the guide member.
