Genuine MTD hex-head screw 710-0412 — a 1/4-28 (≈6.35 mm diameter, ~0.91 mm thread pitch) hex screw with a length of 0.75 in (≈19.05 mm). Designed for fast, reliable reassembly of engine and chassis components on MTD-family lawn & garden machines; it replaces older part numbers such as 1100002, 1509-125 and 1509-165.
Fits a range of MTD, Cub Cadet, Troy-Bilt and Ryobi equipment — examples include MTD rear‑tine tiller model 450 (21A-450 / related service diagrams), MTD rear‑tine tiller 21AB455C730, Ryobi rear‑tine tiller 21AB454B734 and Troy‑Bilt walk‑behind mower model 12AF753B063. Use this screw where the parts diagram or manual calls for 710-0412 (or its superseded numbers).
Handy for repairs: same head style and thread pitch as original MTD fasteners, so it installs cleanly into the existing tapped holes and holds brackets, shield plates and pulley hardware as shown in original parts diagrams.
