Dorman M12-1.50 Serrated Wheel Studs 10-Pack — 14.20 mm Knurl, 40 mm Length, Carbon Steel (Made in USA)

Dorman M12-1.50 serrated wheel studs are durable, corrosion-tested carbon steel replacement studs designed to restore secure wheel fastening on compatible vehicles.

These 10-pack lug studs provide a direct-replacement option for vehicles that use M12-1.50 threading with a 14.20 mm knurl diameter and 40 mm overall length. Manufactured and inspected in the United States, the studs are built from carbon steel and subjected to tensile and salt-spray tests to meet automotive industry standards, giving you a reliable part when mounting wheels or replacing bent or stripped studs.

How do these studs match my vehicle?

Fit depends on thread pitch, knurl diameter, and length; the Dorman 610-266 studs use M12-1.50 threads, a 14.20 mm knurl, and a 40 mm length to mirror factory dimensions for the specified applications. Always check your vehicle’s wheel hub specifications or use the seller’s fitment tool to confirm compatibility before purchase.

• M12-1.50 thread pitch for compatible hubs and lug nuts
• 14.20 mm knurl diameter to seat securely in the hub bore
• 40 mm overall length for correct washer and nut engagement
• Pack of 10 to replace multiple studs or keep extras on hand

What makes these studs strong and long-lasting?

These wheel studs are made from carbon steel formulated and heat-treated to meet SAE automotive strength and hardness criteria. They undergo proof-load tensile testing and extensive salt-spray exposure to validate performance under stress and resistance to corrosion.

• Carbon steel construction for high tensile strength
• Industry-standard proof-load testing to confirm load capacity
• Salt-spray testing for rust resistance over time
• Quality inspections performed by U.S.-based engineers

How do I install these studs safely?

Installation typically involves pressing or pulling the old stud from the hub and seating the new serrated stud so the knurl locks into the hub bore; torque the lug nuts to the vehicle manufacturer’s specifications. Use proper tools—hydraulic press, stud puller, or appropriate driving method—and follow safety steps such as supporting the vehicle and using thread lubricant only where recommended.

• Remove wheel and brake components as needed to access hub
• Extract damaged stud using a puller or press
• Seat new serrated stud so knurl engages hub bore fully
• Tighten lug nuts to the manufacturer-specified torque

Are these studs resistant to rust and road conditions?

Dorman tests these studs with salt-spray exposure to evaluate corrosion resistance—helpful for vehicles exposed to road salt and wet climates. While the studs are engineered to resist rust longer than untreated hardware, routine inspection and maintenance of wheel mounting hardware are still recommended.

• Salt-spray tested for enhanced corrosion resistance
• Carbon steel grade chosen for durability in harsh conditions
• Recommended for routine checks in corrosive environments
• Backed by Dorman quality control procedures

Who is this for? These Dorman M12-1.50 serrated wheel studs suit DIY mechanics, professional technicians, and fleet owners needing reliable, direct-fit replacement studs for compatible vehicles. Choose this 10-pack when you need proven strength, verified fit dimensions (14.20 mm knurl, 40 mm length), and parts inspected under U.S. quality standards—ideal for restoring wheel security after damaged or worn studs.
