Gibraltar MLL-5-PT-G Locking L Handle Plunger M12x1.75

Product Description

The GIBRALTAR MLL-5-PT-G is a steel locking L-handle plunger designed for industrial and mechanical positioning applications where a secure, repeatable hold is required. Built around an M12x1.75 thread, this plunger delivers an initial end force of 4.5 N and a final end force of 22.3 N, giving installers a firm, controlled lock under load. The 7 mm plunger diameter and 19 mm plunger projection make it well-suited for fixture plates, jigs, machine slides, and other precision workholding setups. The locking element engages positively so the plunger stays retracted or extended without continuous manual pressure. Total assembled weight is 0.1 pounds.

The MLL-5-PT-G is used in machine tool fixtures, workholding assemblies, assembly jigs, and industrial positioning equipment where a threaded locking plunger is needed to index or secure a moving component. The M12x1.75 thread size fits standard metric-tapped holes common on fixture plates and machine bases. The 1.11-inch thread length provides adequate engagement depth in typical fixture plate materials. This plunger is installed by machinists, toolmakers, and maintenance technicians in light to medium industrial environments.

Key Features

• Locking L-handle design keeps plunger held in retracted or engaged position without continuous hand pressure
• M12x1.75 thread with 1.11 inches of thread length for secure engagement in metric-tapped fixture plates
• Initial end force of 4.5 N rising to a final end force of 22.3 N for positive, repeatable indexing
• 7 mm plunger diameter with 19 mm plunger projection suits standard fixture plate indexing holes
• Steel handle construction for durability in machine shop and production environments
• Compact 54 mm body length with 32 mm length under head for space-constrained installations

Compatibility

Designed as an OEM-style or direct replacement locking plunger for metric fixture plates, jigs, and machine slides with M12x1.75 tapped holes requiring a 7 mm plunger bore.

Installation Notes

Installation is performed by toolmakers, machinists, or maintenance technicians using a standard metric wrench sized for the 12 mm hex. Ensure the mating tapped hole is clean and free of debris before threading in the plunger. De-energize or lock out any associated powered equipment before servicing or replacing plungers in active fixture assemblies. Do not exceed the rated end force by overtightening the locking element.
