018-6020-00 Replacement Blade Bolt for Bad Boy, 3-Pack | Fits ZT, CZT, MZ Models, Fits Outlaw, Magnum, Maverik, New

What It Is

This is a 3-pack of replacement blade bolts (part number 018-6020-00) designed for Bad Boy zero-turn mowers. Each bolt secures the mower blade to the spindle assembly, making them a direct consumable replacement for models like the ZT, CZT, MZ, Outlaw, Magnum, and Maverik.

Fitment & Compatibility

Check these before buying:

• Deck size/type: Fits 42", 48", 50", 54", 60", and 72" Bad Boy decks that use a 5/16"-18 x 1-1/4" bolt with a 1/2" hex head. Measure your current bolt length and thread pitch if unsure.
• Model range: Confirmed for ZT, CZT, MZ series, plus Outlaw, Magnum, and Maverik. Not listed for all Bad Boy models—verify your deck’s spindle bolt specs.
• OEM vs aftermarket: This is a non-OEM replacement. It matches Bad Boy OEM part 018-6020-00 but may differ slightly in finish or thread tolerance.
• Bolt spec: 5/16"-18 thread, 1.25" length, grade 5 or similar. Do not use on decks requiring a different thread pitch (e.g., 3/8"-24) or length.

Key Things to Know

• Torque is critical: Tighten to 30-40 ft-lbs (check your manual). Under-torque can cause blade loosening; over-torque can strip threads or snap the bolt.
• Replace with every blade change: Bolts fatigue over time. Always use new bolts when swapping blades to prevent failure.
• Anti-seize recommended: Apply a light coat to threads to prevent galling and make future removal easier, especially on older decks.
• Single review: Only one rating so far (5 stars). No long-term durability data—buy with confidence but inspect after first use.

Should You Buy It

If you own a compatible Bad Boy ZT, CZT, or MZ model and need fresh blade bolts for routine blade changes, this 3-pack is a cost-effective choice. Just double-check your deck’s bolt specs and torque to spec. Skip it if you need OEM-grade finish or have a non-listed Bad Boy model.
