   "A lug nut or wheel bolt is defined by four things: thread, seat, hex and length. The thread has to match the stud or hub, the seat has to match the wheel, the hex has to match your socket; length depends on wheel thickness and thread engagement. The nut or bolt must also match the pattern on the wheel (see wheel-bolt-patterns-pcd-lug-patterns).",
   "Where the sources disagree: the inch 9/16 thread is 9/16-18 in McGard's catalogue, motorverso and trailer hub listings, and 9/16-20 in Wikipedia. Wikipedia also calls 13/16 in a less common hex, while motorverso and McGard treat it as the standard inch match to 21 mm. 13/16 in is 20.64 mm, so a 21 mm socket fits but is not the same size; 3/4 in is 19.05 mm against 19 mm.",
   "Thread major diameters are the nominal designation (M12 = 12.0 mm; 1/2 in = 12.7 mm); pitches are the second number. No tolerance classes or thread forms were read, and wheel-seat angle tolerances are not published in the sources; use the wheel maker's data.",
   "Lug nut lengths are product-specific: Dorman 611-183 (M12-1.50, 19 mm hex) is 0.831 in (21.1 mm) overall and McGard 69432 (M14x1.5, 13/16 hex) is 1.945 in (49.4 mm); the cone, bulge and hub-cap profiles are not given as numbers, so no nut or bolt models are published.",
   "Torque: the sources read do not give general values (Wikipedia: vehicle and wheel maker values apply; wheel-sizes.com prints per-vehicle torque on some pages, 131 Nm for the Toyota Tundra and 133 Nm for the Nissan Titan, which are not repeated as rules). Use the vehicle's manual.",
   "Files: none; this page is numbers only. McGard's catalogue is the maker's listing used for the thread and hex sizes; the maker's own CAD was not found."

   "q": "What size are most lug nuts?",

  },
  {
   "q": "What does 'R13' on a ball-seat lug bolt mean?",
   "a": "13 mm ball radius. R12, R13, R14 and R15 are different radii and must match the wheel's seat."

  {
   "q": "Is a 21 mm lug nut socket the same as 13/16 in?",
   "a": "No: 21 mm is the metric size; 13/16 in is 20.64 mm. A 21 mm socket fits a 13/16 in nut, but they are not equal."
  },
  {
   "q": "What seat angle do conical lug nuts use?",
   "a": "60° normally; 45° on some racing wheels (Wikipedia). Dorman prints 'Conical Seat - 60 deg' for the M12-1.50, 19 mm part 611-183."
