Astro Tools 78345 Long Flex Head Ratchet Wrench for 1/4in Nano Sockets | Astro Pneumatic Tool Company

Overview

Meet the Astro Tools 78345 Long Flex Head Ratchet Wrench, purpose-built to work with Astro Nano style 1/4in drive sockets that feature an 11mm outer hex. The tool’s working height is an impressively low 0.88 inches, letting you slip it into cramped pockets of an engine bay, under dashboards, or along bike frames with minimal clearance. The extended 10-inch length provides reach for fasteners tucked behind hoses or brackets, helping you maintain control while freeing your other hand for alignment or support.

At the heart of the 78345 is a 100-tooth ratcheting mechanism paired with a polished teardrop handle. This combination delivers smooth, precise increments and a comfortable grip even during long sessions. The c-clip design keeps 1/4in Nano sockets securely retained, so you can move between sizes without interruptions. When used with Astro Nano socket sets, this wrench not only complements existing tools like the 78113 Metric and 78110 SAE sets but also fits into a growing family of 1/4in drive Nano accessories planned for the future.

Designed for real-world use

In everyday maintenance—from automotive dashboards to motorcycle engine bays—fasteners may resist at awkward angles. The 78345's long reach helps you approach from a more favorable angle, while the low height reduces the risk of binding against nearby components. The teardrop handle is finished for a comfortable grip during longer sessions, and the 100-tooth mechanism offers steady, controlled ratcheting that improves speed without sacrificing precision.
