Value Collection BDNA-7591 Button-head Grease Fitting

Product Description

The VALUE COLLECTION BDNA-7591 is a button-head grease fitting designed to deliver lubricant from a grease gun to a bearing, joint, or pivot point in mechanical equipment. The button-head profile accepts a flush-mount grease coupler, which allows lubrication in tight clearance areas where a standard zerk-style fitting cannot be reached easily. Threaded at 1/4-18, this fitting installs directly into a tapped port on the component being serviced. Maintenance technicians, millwrights, and equipment service professionals use button-head fittings as part of routine preventive maintenance programs on industrial and commercial machinery.

Button-head grease fittings are used across a wide range of applications including conveyor systems, agricultural equipment, material handling machinery, automotive chassis components, and HVAC equipment with lubricated bearing assemblies. The 1/4-18 thread size is one of the most common thread specifications in North American equipment, making this fitting suitable for general-purpose lubrication port replacement or new installation where that thread standard is called out in the equipment service manual.

Key Features

• Button-head fitting profile accepts flush-mount grease couplers for use in restricted-access locations
• 1/4-18 thread size matches the most widely used North American grease fitting thread standard
• Compact form factor suited for tight clearance lubrication points
• Direct-install replacement for worn or damaged button-head fittings on existing equipment

Compatibility

Designed as a general-purpose button-head grease fitting replacement for mechanical equipment with 1/4-18 tapped lubrication ports.

Installation Notes

Button-head grease fittings are typically installed by maintenance technicians or millwrights using a properly sized wrench or fitting driver. Always de-energize and lock out the equipment before replacing a grease fitting on any moving or pressurized assembly. Thread the fitting in by hand first to avoid cross-threading, then tighten to snug with a wrench - do not overtighten into aluminum or soft metal ports. After installation, purge the fitting with a flush-mount grease coupler to confirm the check valve seats and lubricant flows correctly.
