Value Collection BDNA--7578-2 Drive-in Grease Fitting

Product Description

The VALUE COLLECTION BDNA--7578-2 is a drive-in grease fitting with a 1/4-28 thread size and a zinc plated finish. Drive-in fittings are pressed directly into a pre-drilled hole without threading, making them a fast, reliable solution for adding a lubrication point to bearings, pins, shafts, and other mechanical components. The zinc plating provides basic corrosion resistance for indoor and light-duty applications. This fitting is a standard maintenance item stocked by industrial and mechanical contractors who service rotating equipment, conveyors, and general machinery.

Drive-in grease fittings with a 1/4-28 thread specification are widely used in industrial maintenance, fleet service, and equipment repair environments. They are suitable for installation on agricultural equipment, material handling systems, light manufacturing machinery, and similar applications where periodic lubrication is required. Mechanics and maintenance technicians typically stock these fittings in bulk to support scheduled preventive maintenance programs.

Key Features

• Drive-in installation — pressed into a pre-drilled hole without threading required
• 1/4-28 thread size for compatibility with standard grease gun fittings
• Zinc plated finish for basic corrosion resistance
• Lightweight construction suited for high-volume maintenance applications
• Standard UNSPSC Code 40141700 classification for industrial procurement systems

Compatibility

Designed as a standard drive-in grease fitting for use on bearings, pins, and mechanical assemblies that require periodic lubrication access points with a 1/4-28 specification.

Installation Notes

Drive-in grease fittings are installed by a mechanic or maintenance technician using a press, hammer, or installation tool to seat the fitting flush into a properly sized pre-drilled hole. Ensure the receiving hole diameter matches the fitting shank before installation to achieve a secure press fit. Clean the bore and surrounding area before pressing the fitting to prevent contamination of the lubrication path. Do not over-drive the fitting, as this can damage the internal ball check valve and restrict grease flow.
