Single Sizes
Pick a crowfoot wrench in the exact size you need. Choose the drive (e.g. 1/4 inch) and the opening in millimetres. The profile determines how it grips the bolt, and the finish protects against corrosion. Length gives the right leverage in tight spaces. Buy only what you use, no unnecessary extras.
Crowfoot wrench per size
Pick the right size and drive
You buy a crowfoot wrench in one size here. That way you don't pay for a whole set. First check the drive, for example 1/4 inch. Then check the opening size in millimetres. It must fit the bolt or nut exactly.
Where ordering goes wrong
The biggest mistake is choosing an opening size that is close but not right. A 13 mm wrench won't work on a 12 mm bolt. Always measure the bolt. Also check the profile. A Torx profile needs a Torx key, not an Allen key. If you are unsure between profiles, see the overview in Hex & Torx Keys.
Length and access
The length of the wrench determines the leverage. An extra long version gives more force but takes up more space. In tight spots, a shorter wrench is easier to handle. Choose the length that suits the access to your workspace.
