Product Introduction

Every socket is precision forged from premium Cr‑V chrome‑vanadium steel with thick reinforced walls and fully heat‑treated for exceptional impact strength and torque resistance. The long deep‑well body reaches deeply seated and long‑shank fasteners that standard sockets cannot reach. Its 6‑point inner profile grips nuts securely and minimizes the risk of rounding corners under heavy force. Unlike regular black oxide sockets, these sockets adopt manganese phosphate surface treatment, which provides better wear resistance, anti‑slip performance and rust protection in oily, gritty workshop environments. Each socket uses universal 1/2" (12.5 mm) square drive with a retaining pin hole for safe mounting on heavy‑duty pneumatic impact guns and electric impact wrenches. The set comes in a durable blow‑molded plastic carrying case to keep sockets organized and protected during transport and storage. It is an essential stocking tool for hardware wholesalers and heavy‑service repair workshops.
