Why customers choose TaskHolt Tools

Meet the Astro Tools 78314 set, a 14-piece metric nano socket collection designed for a 3/8 drive. Brought to you by AP Astro Pneumatic Tool Company, these sockets are forged CR-MO with precision broaching to deliver dependable performance in demanding workspaces. At just 0.88 inches long (22.5 mm), they sit 35% shorter than standard shallow impact sockets and 15% shorter than many other stubby designs, providing a compact profile that helps you reach fasteners in tight areas. The outside hex measures 17 mm, offering improved clearance when used with a wrench and reducing effort in cramped engine bays.

The materials and build support longevity and reliable torque transfer. The set features forged CR-MO steel with a thicker wall design between the socket body and drive, which contributes to durability during repeated use in busy shop environments. With accurate metric sizing and a 14-piece lineup, you gain broad fastener coverage without constantly swapping tools, helping you stay focused on the task at hand. This combination of compact form, solid construction, and practical sizing makes the Astro Tools 78314 a versatile addition to professional and DIY tool kits alike.
