Overview
The Astro 78301 is a compact box-end wrench targeting the 17mm fastener size, with a listed length of 4.5 inches and a weight of 0.21 kilograms. That short overall length is the defining feature: it is purpose-built to reach fasteners in areas where a standard-length wrench cannot swing freely.
With 200 units sold last month and a 4.8-star rating across 111 owner reviews, the Astro 78301 shows real, sustained buyer demand. At $33.99 it is priced toward the mid-range for a single-size specialty wrench, which reflects its professional-grade positioning.
The 17mm size is a common target for suspension bolts, wheel-speed sensor housings, and various engine fasteners, making the stubby length especially practical for in-situ repairs where a ratchet cannot engage.

Performance notes
At 4.5 inches overall, the Astro 78301 is designed for access in confined spaces rather than maximum leverage. The 17mm box end fits common metric fasteners encountered in automotive work. The 0.21 kg weight keeps the tool easy to control in overhead or one-handed positions.
