The 2018 Chevrolet Silverado 1500 uses six lug nuts with an M14 x 1.5 thread. The specified installation torque is 140 lb-ft (190 Nm). Its wheel fitment data includes a 6x139.7 bolt pattern and a 78.1 mm center bore, but the bolt pattern alone does not confirm that a wheel or fastener is compatible.
The supplied facts do not list the lug nut seat type or socket size. Replacement hardware for OEM or aftermarket wheels still needs a seat-type check, along with confirmation of the thread. A wheel with a center bore smaller than 78.1 mm cannot be installed on this hub.

Frequently asked questions
Does the 2018 Chevrolet Silverado 1500 use lug nuts or lug bolts?
The supplied specification lists lug nuts, not lug bolts, for the 2018 Chevrolet Silverado 1500. The thread is M14 x 1.5, and the vehicle has six lug positions.
What thread size do the lug nuts use?
The listed lug nut thread is M14 x 1.5. Matching the thread alone does not confirm complete fitment; the lug nut must also suit the wheel’s seat. Seat type is not listed in the supplied facts.
What is the lug nut torque for a 2018 Chevrolet Silverado 1500?
The specified wheel fastener torque is 140 lb-ft (190 Nm).
How many lug nuts does the 2018 Chevrolet Silverado 1500 use?
The Silverado 1500 has six lug positions and a 6x139.7 bolt pattern. The bolt pattern and lug count should be checked along with the M14 x 1.5 thread, center bore, and wheel seat before installing replacement hardware.
What center bore and bolt pattern should be checked with replacement wheels?
The listed center bore is 78.1 mm. A wheel with a smaller center bore than the 78.1 mm hub cannot be installed. A matching bolt pattern by itself does not guarantee wheel compatibility.
Can I use any M14 x 1.5 lug nuts or wheel locks?
Seat type and socket or hex size are not listed in the supplied facts. For OEM or aftermarket wheels, confirm that the replacement lug nuts use the M14 x 1.5 thread and match the wheel’s seat before installation. The same check applies to wheel-lock hardware.
Thread, torque and fastener type come from the OEM catalog. Seat type and socket size are not listed for this vehicle, so lug nuts that match the thread still need a seat-type check.
