5630351002 Lawn Mower Blade Bolt Bolt Nut & 5640226002 Center Flange Bolt & 5650705002 Washer for EGO 21" Lawn Mowers LM2130 LM2130SP LM2150SP

What It Is

This is an OEM hardware kit for EGO 21-inch lawn mowers, including the blade bolt (5630351002), center flange bolt (5640226002), and washer (5650705002) needed to secure or replace the cutting blade on select models.

Fitment & Compatibility

• Exact fit for: EGO LM2130, LM2130SP, and LM2150SP 21" mowers.
• OEM vs aftermarket: Genuine EGO parts; aftermarket bolts may have different thread pitch or head size, risking improper torque or blade slippage.
• Check before buying: Confirm your mower model number (on the deck or manual). These bolts are not for EGO 20" or 56V push mowers with different deck designs.
• Measurements: Bolt is M8x1.25 thread, ~20mm length. Washer is 24mm OD, 8.5mm ID. The center flange bolt is M8x1.25 with a built-in flange.

Key Things to Know

• Installation difficulty: Easy—requires a socket or wrench (typically 13mm or 15mm) and a torque wrench (recommended 30-35 ft-lbs). Over-tightening can strip threads or crack the blade adapter.
• Common gotcha: Reuse old bolts or washers that are worn or corroded; this can cause blade wobble or detachment. Replace all three parts together for safety.
• Quality: OEM parts are zinc-plated for corrosion resistance. Aftermarket bolts may rust quickly or have incorrect thread pitch, leading to stripped holes.
• Tip: Always check blade balance after installing new hardware—unbalanced blades vibrate and can loosen the bolts over time.

Should You Buy It

If you own an EGO LM2130, LM2130SP, or LM2150SP and need to replace lost, damaged, or worn blade fasteners, this OEM kit is the safest choice. It’s also a good spare to keep on hand for blade changes. Skip it if your mower is a different model or if you only need a single bolt—buying the full kit is still cheaper than sourcing individual OEM parts.
