How the points were given
Each bar is scored out of 10 on performance, build, value, safety and warranty, with the weights published on our How We Pick page. A stated ANSI or ASME standard earns safety points; a listing with no standard stated scores nothing for safety.

What the listings tell you
We read 5 breaker bar listings for this guide. Two state a safety standard: the NEIKO meets ASME B107.110-2012, and the VÄRMA is rated to 284.2 N·m and exceeds ANSI standards by 1.4 times. None of the five state a warranty term. Four of the five list a spring-loaded ball that holds sockets in place.
Three of the five are 15 inch bars, and the other two run 18 and 24 inches. The HORUSDY set adds a 6 inch bar and a 10 inch bar beside its 15 inch bar. Treat the spec table weights with care: the NEIKO table lists 0.000625 pounds and the VÄRMA table lists 0.2425084882 pounds, neither of which matches a steel bar of that length.
Buying guide: choosing the best 3/8 breaker bar
Length and leverage
A longer bar gives more leverage for a stuck nut. The WORKPRO bar runs 24 inches, the Capri 18 inches, and the NEIKO and VÄRMA bars 15 inches. The HORUSDY set covers 6, 10 and 15 inches.
Flex head
Every bar here has a flex head. The HORUSDY, NEIKO and VÄRMA heads turn 180 degrees, the WORKPRO head turns 360 degrees, and the Capri head turns 230 degrees. A head that holds its angle helps in tight spaces, and the VÄRMA listing says its washer-tension system keeps constant tension.
Drive size: 3/8 or dual drive
All five take 3/8 inch sockets, and the WORKPRO also takes 1/2 inch sockets with its dual drive ends. If you are choosing between drive sizes, read our 1/2 vs 3/8 breaker bar comparison.
Breaker bar or torque wrench
A breaker bar breaks nuts loose; a torque wrench measures torque for tightening. Read our torque wrench vs breaker bar comparison before you buy.
Garage Fit Check
- Check the length against your workspace: the bars run from 6 to 24 inches, with the longest at 24 inches.
- Match the drive to your sockets: all five take 3/8 inch sockets, and the WORKPRO also takes 1/2 inch sockets.
- Check the socket lock before the first job: four of the five list a spring-loaded ball that holds sockets in place.
- Check the rating before heavy work: the VÄRMA bar is rated to 284.2 N·m, and the NEIKO bar meets ASME B107.110-2012.
Use rated jack stands on solid ground, wear eye protection with power and air tools, keep fuel-burning equipment out of a closed garage, and follow the manual for every tool. Read our Safety Disclaimer.
FAQ: garage tools

A breaker bar breaks loose stuck, rusted or over-tightened nuts and bolts with leverage from a long handle. It does not ratchet and it does not measure torque.
What length breaker bar do I need?
It depends on the job and the space. The bars here run from 6 to 24 inches, with the WORKPRO at 24 inches and the Capri at 18 inches. Longer bars give more leverage where there is room to swing them.

A 3/8 inch bar suits smaller fasteners. For lug nuts, the WORKPRO bar also takes 1/2 inch sockets, and the HORUSDY set includes a 1/2 inch bar.
Which of these bars state a safety standard?
The NEIKO bar meets ASME B107.110-2012, and the VÄRMA bar is rated to 284.2 N·m and exceeds ANSI standards by 1.4 times. The other three state no standard.
How do I keep sockets from falling off?
