Value Collection MB305859 Button-head Grease Fitting

Product Description

The VALUE COLLECTION MB305859 is a button-head grease fitting threaded at 7/16-27, designed to accept a standard grease gun coupler for lubrication service on industrial and mechanical equipment. The button-head profile allows the coupler to snap on and release quickly, making it practical in tight spaces where standard zerk fittings are difficult to engage. This fitting threads directly into the grease port of the component being serviced. It is installed by maintenance technicians, millwrights, and equipment service professionals across a wide range of applications requiring periodic lubrication.

This fitting is suited for use on bearings, linkages, pivots, and other grease-able components found in industrial machinery, agricultural equipment, automotive assemblies, and general mechanical systems. The 7/16-27 thread size is a common straight thread used across many OEM and aftermarket grease port designs. It is sold individually per package with a minimum order quantity of 3 units.

Compatibility

Designed as a standard replacement or supplemental grease fitting for any mechanical assembly with a 7/16-27 threaded grease port accepting a button-head style fitting.

Installation Notes

Installation is performed by maintenance technicians using a wrench sized for the fitting hex. The receiving component should be de-energized and, where applicable, depressurized before removing or installing grease fittings. Thread the fitting in by hand first to avoid cross-threading, then snug with a wrench. Do not overtighten, as grease fitting bodies can shear or strip the port threads in soft materials.
