Gibraltar 67081G Threaded Spring Plunger M5 X 0.8 Steel

Product Description

The GIBRALTAR 67081G is a threaded spring plunger designed for indexing, positioning, and light-duty locking applications in mechanical assemblies. The steel body with a Delrin nose delivers reliable spring-loaded engagement without marring mating surfaces. Thread size is M5 x 0.8 with a 19 mm (0.748 inches) thread length. The plunger projects 3 mm (0.118 inches) beyond the nose and reaches a maximum plunger diameter of 2.36 mm (0.093 inches). Initial end force is 2.89 pounds and final end force is 11.02 pounds, making this unit suitable for applications requiring moderate, repeatable detent force. No locking element is included. The black finish provides basic corrosion resistance for indoor use.

This spring plunger is used in fixture building, tooling plates, jigs, machine tool setups, and general industrial assemblies where a compact M5-threaded nose-plunger is required. The Delrin nose reduces wear on softer mating materials compared to all-steel alternatives. Typical installers include tool and die makers, millwrights, maintenance technicians, and precision assembly workers. The unit installs into any M5 x 0.8 threaded hole and requires no special hardware beyond a hex key for the 2.5 mm hex drive.

Key Features

• M5 x 0.8 thread with 19 mm (0.748 inches) thread length for standard metric tapped holes
• Delrin nose minimizes surface damage on soft or sensitive mating materials
• Steel body construction for durability in industrial environments
• 2.89 lb initial end force and 11.02 lb final end force for consistent detent engagement
• 3 mm (0.118 inches) plunger projection for reliable indexing travel
• Black finish and no locking element for straightforward installation and removal

Compatibility

Designed as an OEM-style replacement or direct-fit component for any mechanical assembly or fixture accepting an M5 x 0.8 threaded spring plunger with a 19 mm thread length.

Installation Notes

Install into a clean, properly tapped M5 x 0.8 through-hole or blind hole using a 2.5 mm hex key. Verify hole depth accommodates the full 19 mm thread length before installation. De-energize or lock out any associated machinery before servicing assemblies containing this plunger. Do not overtighten, as this can compress the internal spring beyond its working range and reduce detent force.
