Parts for your 2016 Subaru Impreza-Wheel studs nuts

2016 Subaru Impreza wheelstudsnuts — what they do and how to look after them

Based on Subaru’s technical literature — including the 2016 Impreza Owner’s Manual (Wheels and Tyres) and the factory Service Manual for the GP/GJ chassis — this vehicle uses wheel studs with separate wheel nuts (often called wheelstudsnuts). Each hub carries five press-in studs, and the wheel is secured with matching M12 x 1.25 nuts tightened to 120 N·m (about 88.5 ft‑lb). So yes, wheelstudsnuts are absolutely relevant and fitted on a 2016 Subaru Impreza.

On this model, the studs provide the fixed threaded posts, while the nuts deliver the clamping force that holds the wheel firmly against the hub face. That clamping keeps the wheel centred, maintains brake rotor alignment, and resists cornering and braking loads. Most 2016 Impreza trims use 60‑degree tapered (conical) seat nuts for both steel and many OEM alloy wheels, always match the nut seat to the wheel design if aftermarket rims are fitted.

As part of routine servicing, these wheelstudsnuts deserve a quick once-over. Subaru specifies tightening to 120 N·m on clean, dry threads — avoid oil, grease or anti‑seize unless a service bulletin specifically says otherwise, because lubrication changes torque-to-clamp relationships. After any tyre rotation, puncture repair, or wheel change, it’s good practice to recheck torque after 50–100 kilometres.

Replacement is straightforward when needed. Stretched, cross‑threaded or rusty studs should be pressed out of the hub and replaced with OE‑spec items, damaged or rounded nuts should be swapped for quality M12 x 1.25 nuts with the correct seat style and hex size. If the chrome caps on capped nuts deform, replace them rather than forcing a socket on — that’s how studs get hurt.

• Use a star pattern when tightening the five nuts to seat the wheel evenly.
• Clean the hub face and wheel mounting pad, corrosion here reduces clamp load.
• Do not rely on a rattle gun for final torque — finish with a calibrated torque wrench.
• If using aftermarket wheels, confirm the seat type and nut length, open nuts may be needed with long studs.
• Any stud that’s been significantly over‑torqued or heated (e.g., from brakes dragging) is cheap insurance to replace.

All up, keeping the 2016 Subaru Impreza’s wheelstudsnuts clean, correctly matched, and torqued means quieter rides, happier brakes, and fewer dramas at the next tyre service.

Popular questions about 2016subaruimpreza wheelstudsnuts

What’s the correct wheel nut torque for a 2016 Subaru Impreza?

The specified torque is 120 N·m (about 88.5 ft‑lb) on clean, dry threads. Use a star pattern across the five nuts to seat the wheel evenly.

After any wheel or tyre work, recheck torque after 50–100 kilometres to confirm the clamp load hasn’t relaxed.

What thread size and seat type do the wheelstudsnuts use?

The 2016 Impreza uses M12 x 1.25 wheel studs and matching nuts. Most trims use a 60‑degree tapered (conical) seat nut.

If you’re running aftermarket rims, verify the seat style — conical vs mag/flat — and always match the nut to the wheel for proper clamping.

When should wheel studs or nuts be replaced?

Replace studs if threads are stripped, the stud has stretched, or there’s heavy corrosion. Nuts should be swapped if the hex rounds off, caps deform, or seat faces are damaged.

Any time a nut feels gritty or won’t run on smoothly by hand, stop and inspect — forcing it can damage the stud and risk wheel loosening.
