An apparatus for facilitating fastening of a fastener, the apparatus comprising a body portion that extends distally from a body proximal portion to a body distal portion ; and a head portion that extends distally from the body distal portion, the head portion comprising: a first prong that extends distally from a first prong proximal section that has a first thickness to a first prong distal section that has a second thickness that is less than the first thickness; and a second prong that extends distally from a second prong proximal section that has a third thickness to a second prong distal section that has a fourth thickness that is less than the third thickness, wherein the second prong is spaced apart from the first prong to define a gap therebetween that is configured to receive the fastener, characterised in that the first thickness and the third thickness are substantially identical and are substantially constant along a first length and a second length of the first prong proximal section and the second prong proximal section, respectively, and wherein the second thickness and the fourth thickness are substantially identical and are variable, tapering distally along a third length and a fourth length of the first prong distal section and the second prong distal section, respectively. a body portion that extends distally from a body proximal portion to a body distal portion ; and a head portion that extends distally from the body distal portion, the head portion comprising: a first prong that extends distally from a first prong proximal section that has a first thickness to a first prong distal section that has a second thickness that is less than the first thickness; and a second prong that extends distally from a second prong proximal section that has a third thickness to a second prong distal section that has a fourth thickness that is less than the third thickness, wherein the second prong is spaced apart from the first prong to define a gap therebetween that is configured to receive the fastener, characterised in that the first thickness and the third thickness are substantially identical and are substantially constant along a first length and a second length of the first prong proximal section and the second prong proximal section, respectively, and wherein the second thickness and the fourth thickness are substantially identical and are variable, tapering distally along a third length and a fourth length of the first prong distal section and the second prong distal section, respectively. a first prong that extends distally from a first prong proximal section that has a first thickness to a first prong distal section that has a second thickness that is less than the first thickness; and a second prong that extends distally from a second prong proximal section that has a third thickness to a second prong distal section that has a fourth thickness that is less than the third thickness, wherein the second prong is spaced apart from the first prong to define a gap therebetween that is configured to receive the fastener, characterised in that the first thickness and the third thickness are substantially identical and are substantially constant along a first length and a second length of the first prong proximal section and the second prong proximal section, respectively, and wherein the second thickness and the fourth thickness are substantially identical and are variable, tapering distally along a third length and a fourth length of the first prong distal section and the second prong distal section, respectively. <EOS>
