Abstract
A tool (100) for use with a fastener includes a drive shaft (110) extending along a longitudinal axis (X) from a proximal end (102) to a distal end (104). The tool has an engaging tip (122) at the distal end (104) of the drive shaft (110) sized and shaped to detachably engage a fastener such that the engaging tip (122) is rotationally fixed to the fastener when the engaging tip (122) is engaged with the fastener. The tool (100) further includes a compressible engagement member (150) detachably coupled to the drive shaft (110). The compressible engagement member (150) extends from the engaging tip (122) and is sized and shaped to detachably engage with a receiving portion of the fastener. In an undeformed configuration, the compressible engagement member (150) has a width greater than the receiving portion.
