Dorman Serrated Wheel Studs M12-1.25 — 10-Pack, 14.38 mm Knurl, 43.5 mm Length for Scion/Subaru/Toyota

Dorman M12-1.25 serrated wheel studs are carbon-steel replacement studs engineered to restore safe wheel mounting on compatible Scion, Subaru and Toyota models.

If a wheel stud is worn, damaged, or corroded, replacing it with a correctly sized, tested stud is essential for secure wheel retention. These Dorman studs are manufactured to automotive industry standards, receive tensile and corrosion testing, and are supplied as a 10-pack so you can replace multiple studs at once. Before purchasing, verify fit by checking your vehicle’s make, model, year and trim.

How do these studs match my vehicle’s requirements?

These studs are M12-1.25 thread pitch with a 14.38 mm knurl diameter and a 43.5 mm overall length — dimensions chosen to match OE-style fitment for listed vehicles. They will work when your hub or rotor accepts a serrated knurl of that size and the thread pitch matches your lug nuts.

• Thread size: M12 x 1.25
• Knurl diameter: 14.38 mm serrated
• Total stud length: 43.5 mm
• Sold as a 10-piece pack for multi-stud replacement

What vehicles are these studs compatible with?

This Dorman stud is designed to fit many Scion, Subaru and Toyota platforms across several model years. Compatibility covers popular Subaru models like Impreza, Forester, Outback, Legacy, WRX / WRX STI, Crosstrek/ XV, BRZ and larger models such as Ascent and Tribeca, plus Scion FR-S and Toyota 86 in the years listed.

• Check specific years and trims for Scion FR-S, Toyota 86, Subaru BRZ, WRX, WRX STI
• Includes many model years for Impreza, Forester, Outback, Legacy, Crosstrek
• Use vehicle lookup (e.g., Amazon Garage) to confirm fit for your trim
• Not universal — ensure knurl and thread match your hub design

What quality and testing standards were applied to these studs?

Dorman manufactures these studs from carbon steel and subjects them to industry-standard mechanical tests to confirm strength and corrosion resistance. The parts go through tensile (proof-load) checks and salt-spray exposure equivalent to extended roadside conditions.

• Carbon steel construction for tensile strength and durability
• 72-hour salt spray testing for corrosion resistance
• Proof-load tensile testing to validate load capacity
• Quality oversight by Dorman engineers and U.S.-based QC teams

How should I install and inspect replacement wheel studs?

Installation typically involves pressing the new stud into the hub and securing it with the wheel and lug nut to draw the stud fully into position. Always follow vehicle service manual torque values and inspect hub bore and knurl seating before driving.

• Clean the hub bore and remove debris before installing
• Press or drive the stud in squarely; avoid damaging threads
• Tighten wheel nuts to manufacturer torque specifications
• Recheck torque after a short test drive and periodically thereafter

Who is this for: Automotive DIYers, independent mechanics, and fleet technicians who need a reliable, lab-tested replacement wheel stud for Scion, Subaru or Toyota vehicles listed above. This 10-pack suits drivers replacing multiple studs during rotor or hub service, and shops requiring consistent, USA-backed quality controls. Always confirm thread pitch, knurl diameter, and length against your vehicle’s hub specifications before ordering.
