3X Blade Bolts 109-9220 12633 3213-6 Compatible with Exmark Lazer Z AC AS CT XS Zero-Turn Turf Tracer Vantage S X Series

What It Is

This is a pack of three replacement blade bolts (OEM cross-reference 109-9220, 12633, 3213-6) designed to secure mower blades on Exmark zero-turn mowers. Specifically made for Lazer Z, AC, AS, CT, XS, Turf Tracer, Vantage S, and X Series models. Use these when your original bolts are stripped, rusted, or lost during blade replacement.

Fitment & Compatibility

Check before buying:

• Deck size: Fits Exmark 42", 48", 50", 52", 54", 60", and 72" decks on the models listed. Does not fit older Lazer Z with different bolt patterns.
• Model years: Confirmed for 2000–present Lazer Z, AC, AS, CT, XS, Turf Tracer, Vantage S, and X Series. Verify your deck part number if pre-2000.
• OEM cross: Replaces OEM part numbers 109-9220, 12633, and 3213-6. Aftermarket, not OEM.
• Measurements: Bolt is 5/16" x 1-1/4" with a 7/16" hex head and 3/8" shoulder length. Thread pitch is 18 TPI (fine thread). Measure your old bolt to confirm—Exmark uses two different bolt lengths depending on deck thickness.
• What won’t work: Not for walk-behind or push mowers, or for Exmark Quest, Radius, or Navigator series (those use different bolts).

Key Things to Know

• Quality: Grade 8 steel, zinc-plated. Comparable to OEM, but some users report the hex head is slightly shallower—use a 6-point socket to avoid stripping.
• Installation: Torque to 35–40 ft-lbs. Do not reuse old lock washers; these bolts come with new ones, but you may want to add a drop of blue Loctite for extra security.
• Common gotcha: The shoulder length must match your blade stack height. If you run a mulching kit or blade adapter, these bolts may be too short—measure blade stack thickness before buying.
• Pack size: You get 3 bolts, enough for a single spindle. If your deck has 3 spindles, you need 2 packs. For 4-spindle decks, buy 2 packs.

Should You Buy It

Buy this if you need a quick, affordable replacement for stripped or lost blade bolts on a compatible Exmark zero-turn and don’t mind aftermarket parts. Skip it if you prefer OEM for peace of mind, or if your deck uses a different bolt length or thread pitch. For standard blade swaps on common Lazer Z models, this is a solid value at $8.50.
