5140144-76 is a genuine replacement Clutch Spring for specialized hammer drills and rotary hammers:
Stanley: Specifically used in the STHR323K Rotary Hammer series.
Black & Decker: Compatible with the BPHR323K Rotary Hammer (Type 1).
Functions:
Safety Overload Protection: It is designed to slip when the drill bit binds or hits a hard obstruction (like rebar in concrete), preventing the tool from twisting violently in the user's hands.
Torque Regulation: It manages the transmission of power from the motor to the spindle, ensuring the tool operates within its intended mechanical limits.
Mechanical Integrity: Replacing a worn clutch restores the tool's ability to drive large bits through tough masonry without internal gear slippage
