20-4065/118 Chrome Lug Bolt – 12x1.5 Thread, 17mm Hex, 1.18" Shank, 60° Conical Seat
Part Number: 20-4065/118
The 20-4065/118 chrome lug bolt has a 12x1.50 thread, 17mm hex head, a 1.18" (30mm) shank length, and a 60° conical seat. Manufactured from steel with a polished chrome-plated finish for secure, OE-style wheel mounting on factory and aftermarket wheels.
Lug bolts thread directly into the hub on vehicles that do not use wheel studs — common on European makes such as Audi, BMW, Mercedes-Benz, Volkswagen and Porsche. Available individually, in 2-piece packs, or as a set of 4.

Fitment: How to Confirm This Lug Bolt Fits
Before ordering, confirm all five of the following against your vehicle and wheels:
- Your vehicle uses lug bolts, not studs and nuts
- Thread size is 12x1.50 (not 12x1.25, 14x1.25, or 14x1.50)
- Seat type is 60° conical / tapered — not ball/radius or flat seat
- Shank length of 1.18" (30mm) matches your factory bolt or accounts for wheel and spacer thickness
- 17mm hex clears your wheel's lug hole and center cap
Bolt length must be matched to your specific wheel. A bolt that is too short will not achieve safe thread engagement; a bolt that is too long can bottom out in the hub and prevent the wheel from clamping.
Installation & Torque
Start each bolt by hand to avoid cross-threading the hub, then tighten in a star pattern to the vehicle manufacturer's recommended torque specification using a calibrated torque wrench. Re-torque after the first 50–100 miles of driving. Professional installation is strongly recommended.
Frequently Asked Questions
What thread size is this lug bolt?
12x1.50 with a right-hand thread, also written as M12 x 1.5.
What socket size do I need?
A 17mm lug socket.
What is the difference between a lug bolt and a lug nut?
A lug bolt threads directly into the wheel hub and holds the wheel on by itself. A lug nut threads onto a stud that is already pressed into the hub. They are not interchangeable.
Which length do I need?
Measure the shank of your factory bolt from the underside of the cone seat to the tip. This bolt measures 1.18" (30mm). Adding wheels or spacers that are thicker than stock requires a longer bolt.
How many do I need?
Most vehicles use 4 or 5 bolts per wheel. Count the holes in one wheel and multiply by four, plus spares.
Does it include a washer?
No. This is a standard 60° conical seat lug bolt with no washer and no wheel lock key.
