Bomag 08251213 Domed Cap Nut

The Bomag 08251213 Domed Cap Nut is a genuine OEM fastener designed for Bomag cold milling machines, including the BM1000/30-2, BM1200 30-2, BM1300/30-2, BM 1200/30, and BM 1300/30 series. Sourced directly from Bomag, this component matches the original hardware specification exactly, ensuring correct thread engagement and a flush, secure seating on the fastened assembly. Verified fitment against part number 08251213 gives buyers confidence they are ordering the right hardware the first time.

Key Features

• Genuine OEM Hardware Grade — manufactured to Bomag's original thread pitch and dimensional tolerances, so the dome profile seats squarely and holds torque without deforming over time
• Direct Drop-In Replacement — threads onto the existing stud or bolt without rework, matching the original fastener profile used on the factory assembly
• Broad Cold Milling Machine Coverage — confirmed fit for BM1000/30-2, BM1200 30-2, BM1300/30-2, BM 1200/30, and BM 1300/30 cold milling machines under part number 08251213
• Protective Dome Profile — the closed dome end shields the exposed thread tip from contamination, moisture, and mechanical damage, extending the service life of both the nut and the stud beneath it
• Fastener Integrity Matters — a missing or damaged cap nut leaves threads exposed to the abrasive, debris-rich environment of a milling operation, risking corrosion and eventual joint failure that is far more costly to repair

A domed cap nut is a closed-end fastener that threads onto a bolt or stud to secure a joint while simultaneously covering and protecting the exposed thread end with a rounded dome. On cold milling machines like the BM-series, fasteners operate in a harsh environment where water, dust, and milled material constantly assault exposed metal surfaces. When a domed cap nut is worn, cross-threaded, or missing entirely, the unprotected stud becomes vulnerable to corrosion and mechanical damage, which can compromise joint clamping force and lead to component loosening during operation.
