CRAFTSMAN CMMT45171 71-Piece Mechanics Tool Set

This mechanic's tool set from Craftsman gathers 71 pieces of 1/4 and 3/8 inch drive sockets and accessories to cover common repair and maintenance tasks around the garage. It aims to deliver versatile socket sizes, a low-profile ratchet for tight areas, and a corrosion-resistant finish for durable daily use.

Key Points

The set includes a full range of 1/4 inch and 3/8 inch drive sockets along with extensions and drive accessories to handle automotive work and general mechanical tasks. The low-profile ratchet is up to 25% thinner according to the manufacturer compared to older Craftsman ratchets, helping you reach fasteners in confined spaces. A 72-tooth gear provides a 5-degree arc swing for finer movement when room for leverage is limited. The polished chrome finish helps protect the pieces from rust and allows easier cleaning after use. Compatibility with the Versastack storage system lets you organize this set alongside other modules for a customized workshop layout.

Technical Specifications

• Name: Craftsman CMMT45171 71-Piece Versastack Mechanics Tool Set
• Drive sizes: 1/4 inch and 3/8 inch
• Ratchet gear: 72 teeth, 5-degree arc swing

Usage Recommendations

Use the low-profile ratchet when working in engine bays, behind dash panels, or other narrow service areas where a standard ratchet cannot fit. The combination of 1/4 and 3/8 inch drives covers both small fasteners and mid-size bolts commonly found on motorcycles, cars, bicycles, and home machinery. Keep frequently used sockets in the top row of a Versastack module for faster access and store the rest in the included compartmentation if available.

Nuances and Limitations

According to the manufacturer, the low-profile design improves access but may offer slightly different leverage feel compared to traditional full-size ratchets. The polished chrome finish resists corrosion under normal workshop conditions, however prolonged exposure to harsh chemicals or moisture could still require regular cleaning and drying to maintain appearance and function. The set focuses on drive tools and does not include wrenches or specialty bits beyond the specified sockets and accessories.
