The lug nuts on a 2014 Chevrolet Silverado 1500 are M14x1.50 with a 22 mm outer hex and a conical (60-degree) seat, used with the factory 6-lug, 139.7 mm bolt pattern. They’re typically torqued to about 140 ft-lbs (190 N·m).
In practice, this specification covers most Silverado 1500 models from that year when equipped with the standard wheels, but aftermarket wheels or different trims can require variations. Always verify with the wheel manufacturer or your dealer if you are unsure.
Key lug nut specifications
Before listing the core specs, here is a concise overview of the essential details you should know about the factory lug nuts for the 2014 Silverado 1500:
- Thread size: M14 × 1.50 (metric) — the nut threads onto the wheel studs.
- Hex size: 22 mm (approximately 7/8 inch) — the wrench pocket size for installation/removal.
- Seat type: Conical 60° — the nut seats into the wheel’s lug holes.
- Bolt pattern: 6 × 139.7 mm (6-lug, 5.5 inch C-C)
- Recommended torque: about 140 ft-lbs (190 N·m); re-torque after wheel installation as needed.
These are the factory norms for most 2014 Silverado 1500 configurations. If your vehicle has aftermarket wheels, or you’re mixing lug nuts, verify the exact size and torque with the wheel manufacturer.
Variations with aftermarket wheels
Some aftermarket wheels use different seat styles or lug nut dimensions. To avoid installation issues or damage, confirm the lug nut type required for your wheels and do not mix styles. If in doubt, consult a professional at a tire shop or the wheel manufacturer.
How to verify your lug nut size
If you want to confirm the correct lug nut size yourself, try these steps:
- Check the owner's manual or the tire/wheel specification sheet for the vehicle.
- Inspect the lug nuts or wheel hub area for markings indicating thread size or seat type.
- Measure the lug nut hex with a caliper or ruler to confirm if it’s around 22 mm or another size.
For replacement parts, always match the thread size and seat type to your current wheel setup, and use the recommended torque specification.
Summary
In short: For a 2014 Silverado 1500, the factory lug nuts are M14x1.50 with a 22 mm hex and a 60-degree conical seat, on a 6x139.7 mm bolt pattern, torqued to about 140 ft-lbs. Verify with your wheel manufacturer if using aftermarket wheels, and always torque to specification with a calibrated torque wrench.
