Ball Lock Bolt is a kind of fast fastener with ball locking mechanism, which can be extended or retracted in the locking mechanism through the ball at the end of the bolt to achieve fast and reliable connection and disassembly. It is commonly used in mechanical structures that require high strength locking and fast assembly and disassembly.

Structural features

Bolt Body

Threaded or light bar for mounting and stressing.

Balls (Locking Balls)

Distributed in the locking groove at the end of the bolt, controlled by an internal mechanism.

Internal locking mechanism

The extension and retraction of the ball is controlled by means of a spring or a pull pin.

When locked, the balls expand outward, jamming the mating holes or grooves; when released, the balls retract, facilitating disassembly.

Main Features

Fast locking and releasing: faster than traditional thread tightening, suitable for frequent mounting and dismounting.

High-strength connection: the ball is evenly loaded to ensure firmness and safety.

Precise positioning: Commonly used in working conditions that require high-precision repetitive positioning.

Safe and reliable: some designs with safety latches to prevent accidental loosening.

Ball Lock Bolts are widely used in applications requiring frequent, rapid connection and disconnection:
Jigs and Fixtures: In manufacturing, for quick securing and replacement of molds, fixture plates, and positioning devices.
Machinery Safety Guards: For securing machine guard doors and covers that require periodic opening for maintenance or repairs. Operators can open them by pulling the pull ring, ensuring both safety and convenience.
Aerospace: Secures access panels, interior trim panels, and similar components on aircraft.
