Tekton SID91404 72 Pc Deep Impact Socket Set 3/8 Drive

Product Description

The TEKTON SID91404 is a 72-piece deep impact socket set built around a 3/8 inch drive. It covers both standard and deep profiles in SAE and metric sizes, giving technicians a single organized kit for impact wrench and ratchet work across a wide range of fastener sizes. Sockets are 6-point, which concentrates torque on the flat faces of hex fasteners to reduce rounding. The set ships with two extensions, a universal joint, and a storage rail, keeping components accessible at the bench or in a service vehicle. At 18.1 pounds, the kit has enough mass for a full professional socket complement without being impractical to transport.

This set is suited for automotive, fleet maintenance, and equipment repair applications where both SAE fractional and metric fastener sizes appear on the same job. The 6 to 24 mm metric range and 1/4 to 1 inch SAE range handle the majority of fastener sizes encountered on passenger vehicles, light trucks, HVAC equipment, and general mechanical assemblies. The deep socket profiles provide clearance over studs and protruding bolt threads where standard-depth sockets cannot seat fully. The included 3 inch, 6 inch, and 10 inch extensions extend reach into recessed fastener locations without requiring a separate extension set.

Key Features

• 72-piece set includes standard and deep sockets in both SAE (1/4 to 1 inch) and metric (6 to 24 mm) sizes
• 3/8 inch drive fits the most common impact wrenches and ratchets used in automotive and mechanical service
• 6-point socket geometry reduces fastener rounding under high-torque impact use
• Bright/uncoated finish allows visual inspection of socket condition and simplifies size marking readability
• Three extensions (3 inch, 6 inch, 10 inch) and a universal joint included for varied access angles and depths
• Storage rail included to organize sockets and reduce loss during multi-socket jobs

Compatibility

Designed for use with 3/8 inch drive impact wrenches, air ratchets, and hand ratchets. Compatible with standard 3/8 inch drive accessories including extensions, universal joints, and adapters.

Installation Notes

Select the correct socket size before applying torque to avoid fastener damage. Inspect each socket for cracks or deformation before impact use, as damaged sockets can fail under load. When using with an impact wrench, confirm the socket is fully seated on the drive square before operation. Follow equipment manufacturer torque specifications and applicable service procedures for the application being serviced.
