Gibraltar MSW10-5-G Threaded Spring Plunger M8 X 1.25

Product Description

The GIBRALTAR MSW10-5-G is a standard-length threaded spring plunger designed for indexing, positioning, and light-duty locking applications in machine components and fixtures. The plunger features an M8 x 1.25 threaded body with a 0.866-inch thread length and a steel body construction throughout. The spring delivers an initial end force of 5.62 pounds and a final end force of 15.74 pounds, making it suitable for applications requiring repeatable, moderate-force detent action. The steel nose and body provide durability in industrial environments. Machinists, tool and die makers, and mechanical assembly technicians are the typical installers of this component.

This spring plunger is used in machine tool fixtures, jigs, assembly equipment, and precision mechanical assemblies where consistent detent or positioning force is required. It is threaded directly into a tapped M8 x 1.25 hole in a housing or plate. With a plunger diameter of 0.138 inches and a projection of 0.118 inches, it is suited for applications where a low-profile, small-diameter nose is needed. Typical environments include manufacturing cells, CNC fixture plates, and general industrial machinery.

Key Features

• M8 x 1.25 thread size with 0.866-inch thread length for direct installation into tapped bores
• Steel body and steel nose material for wear resistance in industrial applications
• Initial end force of 5.62 pounds and final end force of 15.74 pounds for repeatable detent action
• Maximum plunger diameter of 0.138 inches and projection of 0.118 inches for low-profile engagement
• No locking element — standard free-turning installation
• Standard plunger length type for common fixture and jig applications

Compatibility

Designed for installation in any housing or plate with a tapped M8 x 1.25 through or blind hole requiring a standard-length spring plunger with a 0.866-inch thread engagement depth.

Installation Notes

Installation requires a properly tapped M8 x 1.25 hole to the appropriate depth. Use a hex key or spanner tool appropriate for the plunger body style and apply thread locker if retention against vibration is needed. Ensure the mating detent surface or ball track is aligned with the plunger nose before final assembly. Do not overtighten, as this can preload the spring and reduce effective travel.
