LawnFlite-Pro 335L-0620 Spare Part - Bolt

MTD 335L-0620 — Flange-style bolt (M6 × 20 mm) designed for fastening blade/spindle and deck hardware on small mowers. The 335L uses metric M6 sizing (the similar 335L-0610 is listed as M6×10 with 1.0 mm thread pitch), so 335L-0620 is the matching 6×20 mm length used where a slightly longer flange bolt is required.

What you’ll get: a single M6×20 mm flange-head bolt (metric thread pitch ~1.0) with the same form factor used in blade mounting hardware — the flange head gives a larger bearing surface for secure clamping without a separate washer. It’s the same style fastener found in blade assemblies (for example on the LawnFlite‑Pro blade assembly FG484_0030 / model 553HRS, where 335L‑0620 is listed as the blade bolt).

Why this matters: if your blade or deck cover requires a longer M6 flange bolt, this part restores correct clamp pressure and alignment so the blade runs true again. Keep in mind bolt length must match the stack-up (spacer + blade + hub) — if you’re replacing a stripped or missing fastener, this M6×20 option is the direct hardware match used in the 335L series.

Note: this is the MTD-style 335L fastener used in mower assemblies and is a straightforward parts-for-power-tools replacement when a longer M6 flange bolt is called for.
