ABSTRACT:
A wrenchless clamp assembly is provided to secure a tool disc, such as a circular saw blade, to a shaft of a power tool. The blade clamp assembly includes an outer flange positionable against an outer side of the blade and a manually tightenable click bolt that includes a movable click member operable to selectively engage the outer flange for rotationally locking or unlocking the bolt. In an embodiment, the click member moves alternatingly between axially engaged and disengaged positions according to sequential rotational increments of the click member relative to the bolt body. Accordingly, the click bolt can be installed by hand and rotationally locked without a need for high torque, and the click bolt can be easily removed by hand when the click member is moved to the disengaged position, axially free from the outer flange. In an embodiment, the click bolt permits limited torque applied during installation.
