Overview
The Astro 78318 is an 18 inch wrench weighing about 1.3 pounds, built with extra length for added leverage on stubborn fasteners.
The long handle is the defining feature here, letting you apply more hand torque than a standard length wrench would without a cheater bar. Jaw size and type are not listed, so match the opening to your fastener before assuming fit.
- 18 inch overall length
- 0.61 kg, about 1.3 lb, weight
- Wrench category tool
- Built for added leverage
Who it's for
Works for anyone dealing with tight or corroded fasteners who wants extra hand leverage. Not the right pick if you already know you need a specific jaw or socket size, since that detail is not confirmed here.
Pros and cons
- 18 inch length gives extra hand leverage
- Under 1.5 lbs, manageable one handed
- Suited to stuck or high torque fasteners
- Jaw type and size not specified
- No indication of adjustable vs fixed jaw
Performance notes
Length is the main mechanical advantage of a tool like this: an 18 inch handle multiplies hand force at the jaw far more than a 6 or 10 inch wrench would on the same fastener.
