Utility workers, plumbers, and maintenance pros - this penta socket set is essential for working on those tricky 5-point pentagon nuts! The set includes two sockets: one with 1/2-inch drive and another with 3/8-inch drive, both fitting 13/16-inch pentagon nuts commonly found on curb boxes, water meters, fire hydrants, and various utility fixtures. The 5-point design provides maximum grip on pentagon fasteners, giving you the torque and control you need without rounding the points. Made from impact-grade steel, these sockets can handle serious abuse from impact wrenches and breaker bars without cracking or deforming. The 3/8-inch drive socket works with most standard ratchets and tools, while the 1/2-inch drive handles heavier torque applications. The precise manufacturing ensures a perfect fit on pentagon nuts without slop or play. Whether you're turning off water mains, maintaining fire hydrants, or working on any equipment with pentagon fasteners, having the right tool makes the job so much easier and prevents damage to expensive components. The two-piece set covers you for different tool sizes and applications. If you're tired of struggling with adjustable wrenches or the wrong tools on pentagon nuts, these purpose-built sockets will save you time and frustration on the job.
