MOUNTING SYSTEMS ball lock pin 6x50 mm

The Mounting Systems ball lock pin 6x50 mm is a high-strength connecting element for quick and tool-free locking of system components. It is primarily used in mobile or modular substructures where parts frequently need to be adjusted, secured or released.

Thanks to the integrated spring mechanism and the locking balls, the bolt provides a form-fit connection that can only be released by deliberately pressing the push button on the handle. This guarantees maximum safety against unintentional slipping out.

Highlights at a glance

• Quick release system: Enables components to be connected and disconnected in seconds without the use of spanners or other tools.
• Self-securing: The spring-loaded balls at the end of the bolt hold the element securely in the hole and prevent it from coming loose under vibration.
• High shear strength: Made of stainless steel or high-strength galvanised steel to ensure maximum stability even under mechanical stress.
• Easy handling: The ergonomic handle (often designed as a T-handle or mushroom head) allows comfortable operation, even when wearing work gloves.
• Weather resistant: Ideal for outdoor use in photovoltaic or event systems as the materials are resistant to corrosion.
• Precision dimensions: A diameter of 6 mm and an effective length of 50 mm ensure an exact fit in standardised system drill holes.

Areas of application

The ball lock pin is a versatile securing element:

• Adjustable mounting brackets
  • Securing telescopic supports or variable tilt angles in PV systems (e.g. seasonal adjustment).
• Modular carrier systems
  • Quick fixation of outriggers, diagonal braces or ballast troughs in flat roof or open-air constructions.
• Trade fair & event construction
  • Connection of aluminium trusses or frame elements that need to be assembled and disassembled regularly.
• Transport protection
  • Locking of moving parts on assembly frames during transport to the construction site.

Installation & safety instructions

• Diameter test
  • Make sure that the mounting hole is exactly 6 mm (H11 tolerance recommended) to avoid play or tilting.
• Complete locking mechanism
  • When inserting, make sure that the balls at the end of the bolt emerge completely and snap into place. This is the only way to ensure full tensile strength.
• Cleaning
  • Keep the spring mechanism and the balls free of sand or coarse dirt to maintain the smooth operation of the push button in the long term.

Properties

FAQs on the 6x50 mm ball lock pin

Can the bolt replace a static screw connection?

Only with appropriate design.

• A ball lock pin is primarily designed for shear forces. For load-bearing, permanent connections in PV statics, the system manufacturer's calculations must be observed. It is not a direct replacement for a firmly tightened M6 bolt with nut.

Is there a captive lock for the bolt?

Optionally available.

• Many users attach a retaining rope (stainless steel wire rope) to the handle of the bolt to prevent the bolt from being lost or falling off the roof when released.

What does the "effective length" of 50 mm mean?

The length of the shaft.

• The 50 mm refers to the area between the base of the handle and the start of the locking balls. The component package that is penetrated may therefore be a maximum of just under 50 mm thick.

Is the bolt rustproof?

As a rule, yes.

• Mounting Systems usually uses stainless steel variants for outdoor applications. Please check the specific material number (e.g. A2/A4) if use in extremely salty sea air is planned.
