The Bomag 05747578 Collar Nut is a genuine OEM Collar Nut designed for Bomag tampers including the BT 60, BT 65, BT 65/4, BT 60/4, BT 60 G, BT 65 G, BT 50, and BVT 65. Sourced directly from Bomag, this component meets the exact dimensional and material standards of the original part it replaces. This Collar Nut installs as a direct replacement, ensuring a correct, secure fit without modification. If you're servicing any of these Bomag tamper models, part number 05747578 is the correct OEM specification component for the job.
Key Features
- Genuine OEM Construction — manufactured to Bomag's exact thread profile and collar geometry, ensuring the same clamping and retention performance as the original fastener
- Direct Drop-In Replacement — engineered to match the original mounting interface on covered tamper models, so this Collar Nut seats and torques correctly right out of the box
- Broad Tamper Coverage — fits BT 50, BT 60, BT 60/4, BT 60 G, BT 65, BT 65/4, BT 65 G, and BVT 65 tampers, making this a versatile stock item for mixed Bomag fleets
- Structural Integrity Maintained — a correctly fitted collar nut keeps critical assemblies properly secured; a worn or damaged fastener can allow loosening under the high-cycle vibration loads these tampers generate
- Verified Part Number Traceability — part number 05747578 cross-references directly to Bomag's OEM parts catalog, eliminating guesswork when ordering service components
A collar nut is a threaded fastener with an integrated flanged collar that distributes clamping load across a wider surface area than a standard hex nut. On a vibratory tamper, components are subjected to intense repetitive impact forces with every stroke of the ram, making fastener integrity critical to safe and consistent machine operation. When a collar nut stretches, strips, or backs off under vibration, it can cause assembly looseness, accelerated wear on adjoining components, or loss of secure connection — making timely replacement with a correctly specified OEM part essential to keeping the tamper performing as intended.
