Cross wrench sizes

A cross wrench (also known as a cross-shaped lug wrench or tire iron) typically has four different socket sizes, one on each arm, to fit various lug nuts or bolts. The exact sizes can vary by manufacturer and region, but common sizes include:

Common Cross Wrench Sizes (Metric & SAE):

• 17 mm (Most common for European/Asian cars)

• 19 mm (Common for many vehicles)

• 21 mm (Used on some trucks and SUVs)

• 22 mm (Common for larger vehicles)

• 13/16" (SAE, common for older American cars)

• 7/8" (SAE, found on some trucks)

• 3/4" (SAE, less common but used in some applications)

Typical Combinations on a Cross Wrench:

• 17 mm, 19 mm, 21 mm, 22 mm (Metric)

• 13/16", 7/8", 19 mm, 21 mm (Mixed SAE/Metric)

How to Determine the Right Size:

• Check your vehicle’s manual for the correct lug nut size.

• Measure the lug nut with a caliper or ruler.

• Test-fit the wrench to ensure a snug fit (avoid rounded nuts).
