Overview
A mechanic working on metric hardware in tight spaces has a use for this Prostormer set. Each wrench pairs an open end with a box end, and the flex-head ratcheting action moves the head to reach awkward fasteners.
Ratcheting heads speed up work because the wrench does not need to be lifted off the fastener between turns. The limitation is that sizes are metric alone, with no size list or case information given.
Who it's for
A garage bench handling metric engine, bike and appliance fasteners suits a ratcheting set. Not a socket set and not an inch set, so buyers with SAE hardware should look elsewhere.
Pros and cons
- Flex heads reach awkward spots
- Ratcheting action saves time
- Open end and box end on each
- Chrome vanadium steel
- Metric sizes only
- Sizes not itemized
- Case not described
Performance notes
A ratcheting head turns the fastener on the working stroke and clicks back freely, so the wrench stays on the nut while the handle swings. Flex-head joints angle the head to clear obstacles, and the open end handles quick spins.
