13mm 3/8 Inch Drive Mid-Length Pinless Universal Impact Sock - Astro Pneumatic

Part #: 78344M04

The Astro Pneumatic 78344M04 13mm 3/8 Inch Drive Mid-Length Pinless Universal Impact Socket is engineered for professional technicians requiring robust performance and exceptional access in constrained workspaces. This specialized impact socket combines a compact overall length with a deeper hex, providing the reach needed for recessed fasteners without the bulk of standard universal sockets. Its innovative pinless design ensures unrestricted movement, making it an indispensable tool for complex automotive and industrial applications.

Key Features

  • Pinless Universal Design: Offers full 360 degrees of freedom for the universal head, allowing it to angle and rotate without the limitations of traditional pinned designs, enhancing access in tight spots.
  • Optimal Mid-Length Profile: Engineered with a mid-size overall length and a deeper hex, providing superior reach for recessed fasteners while maintaining a compact footprint for use in confined areas.
  • 6-Point Secure Grip: The 6-point design delivers a precise and secure engagement with fasteners, reducing the risk of rounding and ensuring efficient torque transfer.
  • Durable CRO-MO Construction: Forged from robust Chrome-Molybdenum (CRO-MO) steel, this impact socket is built to withstand high-torque applications and the demanding conditions of professional use.
  • Lifetime Warranty: Backed by a lifetime warranty, providing assurance of its quality and durability for continuous professional service.
  • 3/8 Inch Drive Compatibility: Designed for use with 3/8 inch drive impact wrenches and ratchets, making it a versatile addition to any professional toolset.

Applications

This 13mm mid-length pinless universal impact socket is particularly well-suited for professional mechanics and industrial technicians who frequently encounter fasteners in challenging positions. It excels in automotive applications such as accessing engine components, transmission fasteners, suspension bolts, and exhaust manifold nuts where clearance is often limited. Its universal joint allows technicians to navigate around obstructions, making it ideal for tasks in confined engine bays, undercarriages, or within machinery where straight access is not possible.
