Original MTD hex-head screw — part 710-0818 — a direct-fit replacement designed for MTD equipment. It’s specified as a 3/8‑24 UNC thread, 2.00 in long (≈50.8 mm) and Grade 8 heat‑treated steel for high tensile strength; thread pitch is 25.4/24 ≈ 1.058 mm.

This hex screw is the same fastener listed to replace 910‑0818 and AM‑006877 and is commonly used to secure keyed engine crankshafts and other drive hardware on older walk‑behind mowers.

Example applications include older MTD walk‑behind models such as 115‑084‑719 and 115‑114‑719 (1985 era), and it’s the same style fastener found across related Cub Cadet, Troy‑Bilt, Bolens and Craftsman machines that share MTD hardware.

Buy this original MTD part if you need a reliable, correctly sized hex screw to finish a repair — it’s listed among MTD parts and is a small, durable replacement that’s handy to have with other parts for power tools when you’re restoring or maintaining garden equipment.
