  • HAND HELD WIND-UP HIGH-POWERED SPRING NON-PENETRATING CAPTIVE BOLT DEVICE
    Publication number: 20240130379
    Abstract: A non-penetrating captive bolt device includes a threaded mechanism for retracting a bolt against a biasing force. The bolt includes an elongated rod that projects rearward from the rear end of the bolt through a compression type spring that biases the bolt forward. A trigger actuated catch is mounted on the threaded mechanism with an internal bore, and the rod extends therein. When the threaded mechanism is advanced forward, the trigger actuated catch is advanced forward and engages the elongated rod. Retracting the threaded mechanism retracts the elongated rod and compresses the spring. Actuating triggers on the trigger actuated catch releases the elongated rod and the spring biases the bolt to a forward position.
