Made-to-Size Crowfoot Wrenches
Pick your opening and drive. Plate thickness, jaw wall and neck are sized for the torque so big wrenches come out heavy-duty. Hardened 4130/4140 chromoly, 42–48 HRC, jaw finished to size after hardening.
Multi-head crowfoots: up to 4 sizes on one drive
Stop digging for the next crowfoot. Put the two, three or four sizes you use on a job on one tool, each head with its own correction factor etched on.
- 2, 3 or 4 heads around one square drive, any sizes the drive can handle
- Every head sized for the torque, same as our single crowfoots
- Each head's E and correction factor etched on the wrench
- One tool to track, tether and hand up the rig instead of four

Ordering, Shipping and How They're Made
Lead time
Stock ships in 2 business days. Custom wrenches up to 1/4" thick ship in about 10 business days (5 with rush). Thicker plate for 1/2" drive and up adds about 5 days. Put a hard deadline in the order notes and we'll tell you within one business day if we can make it.
How big wrenches are sized
Each wrench is sized for the torque its drive is built for, or what the nut needs if that's less. The jaw wall, neck and plate thickness are chosen so the steel stays below its yield point at 1-1/2 times that torque. That's why a 3/4" drive, 3" crowfoot is 1/2" thick and weighs a few pounds.
Torque correction factor
A crowfoot pointing straight out adds length to your torque wrench, so it clicks late. Multiply your target torque by the correction factor to get the setting. We etch the factor for your wrench length on the crowfoot.
Your size isn't listed
Choose "Other" under Opening and type the size in inches or millimeters, or type it in the search box at the top. Custom drive sizes from 1/4" to 2-1/2" are also available.
How they're made
Cut from 4130 or 4140 chromoly plate, heat treated to 42–48 HRC and hardness tested, jaw and drive finished to size, then black oxide or nickel and laser etched. Every order is checked for fit before we cut steel.
Refunds
If we can't make your wrench, or can't make it by your deadline, you get a full refund.
