2017 Case 590sn Lug Nut Torque & Bolt Specs

The 2017 Case 590sn lug nut torque is 310 ft-lbs (420 Nm), tightened with a 33mm socket on M22x1.5 studs. Torque in a star pattern in two passes (snug, then final), and re-check after the first 50–100 miles of driving. Use a calibrated torque wrench — not an impact gun — for the final pass.

Lug nut torque: 310 ft-lbs (420 Nm) · Socket size: 33mm · Thread: M22x1.5.

This page is the OEM-referenced fastener summary for the 2017 Case 590sn. Use it before any maintenance or repair job where torque values matter — brake work, wheel changes, suspension service, engine teardowns, or oil changes. Specs are pulled from manufacturer service literature, cross-checked against community data, and updated as new chassis variants become available.

For the 2017 Case 590sn, fasteners follow metric standards typical of late-model Case engineering. Always confirm spec against the factory service manual before tightening safety-critical fasteners (suspension, brake, steering, head bolts).

Common fastener categories on the 2017 Case 590sn

Wheel / lug nut torque and thread spec (covered above)
Brake caliper bracket bolts (typically 80-130 ft-lbs) and slide/guide pins (18-35 ft-lbs)
Engine oil drain plug torque — rarely above 30 ft-lbs; always use a new crush washer
Transmission pan, valve cover, and intake manifold bolts (low torque, often 89-106 in-lbs)
Suspension control arm, sway bar, tie rod end and ball joint torque
Spark plug torque (typically 10-15 ft-lbs on aluminum heads — do not exceed)
Differential cover bolts (RWD/4WD only) and transfer case fasteners

Repair guidance for this model year

For 2017 model-year work: This era introduced widespread torque-to-yield (TTY) bolts on head, main, and crank pulley fasteners. TTY bolts stretch permanently when torqued and must not be reused — the spec calls for a fresh bolt every time. Always verify TTY status against the FSM before reassembly.

Tools you will need

Metric socket set (8mm-22mm), 6-point impact-rated
Calibrated torque wrench (10-150 ft-lbs covers most automotive jobs; add a 0-250 ft-lbs wrench for truck lug nuts)
Breaker bar (24" minimum) for initial loosening
Penetrating oil (PB Blaster or Kroil) for any fastener over 5 years old
Anti-seize on stainless or dissimilar-metal threads; thread-locker (Loctite blue) on critical reassembly

Frequently asked questions

What is the lug nut torque on a 2017 Case 590sn?

The OEM-specified lug-nut torque for the 2017 Case 590sn is 310 ft-lbs (420 Nm), using a 33mm socket on M22x1.5 thread studs. Use a calibrated torque wrench in a star pattern, in two passes (50% and 100%), and re-check after 50-100 miles of driving.

What socket size do I need for the 2017 Case 590sn lug nuts?

The 2017 Case 590sn uses a 33mm socket. A 6-point impact-rated socket is recommended over a 12-point chrome socket — 12-points round off lug nuts under impact-driver use.

Are the 2017 Case 590sn fasteners metric or SAE?

Metric is the standard for this vehicle. Most fasteners on this vehicle are metric (M6, M8, M10, M12, M14). Bring a full metric set; SAE substitutes can round the head. Bolt-head markings are the fastest way to confirm grade and material at the bench.
