Powered drivers, and kits and methods including or using powered drivers, having a driveshaft extending from a distal end of the housing and configured to slide responsive to a force applied to a distal end of the driveshaft and activate a motor to rotate the driveshaft. Some of the present powered drivers include a housing having a distal end and a proximal end； a motor disposed in the housing； a driveshaft extending outward from the distal end of the housing (e.g., in a direction away from the proximal end)； a gearbox coupled to the motor and to the driveshaft such that activation of the motor will cause rotation of the driveshaft； and a battery configured to power the motor； where the gearbox is slidably disposed in the housing and configured such that, upon application of a threshold force on the driveshaft in the direction of the proximal end of the housing, the driveshaft and gearbox will slide toward the proximal end of the housing and thereby close an electrical circuit between the motor and the battery.
