CRAFTSMAN Mechanics Tool Set, 71-Piece Versastack 1/4 & 3/8 in Drive — Low-Profile 72-Tooth Ratchets, Chrome

CRAFTSMAN Versastack 71-piece Mechanics Tool Set (CMMT45171) is a compact, garage-ready collection of 1/4" and 3/8" drive sockets, low-profile 72-tooth ratchets, and accessories designed to fit the VERSASTACK storage system.

This mechanics set brings a balanced mix of common sockets and drive tools so you can tackle maintenance, repairs, and light fabrication without hunting for individual pieces. Built with a polished chrome finish, the set resists corrosion and the ratchets use a 72-tooth mechanism that requires only a 5-degree swing arc — ideal for tight work areas. The tools meet or surpass ASME standards and are backed by CRAFTSMAN’s Full Lifetime Warranty, making this set suitable as a starter kit or a modular addition to a larger VERSASTACK collection.

How do the ratchets perform in cramped or hard-to-reach spots?

The low-profile heads on the 1/4" and 3/8" drive ratchets are engineered to be thinner than traditional ratchet heads, improving access in confined locations. With a 72-tooth gear, each ratchet provides fine engagement, which reduces the amount of handle movement needed to turn a fastener.

• Up to 25% thinner head for improved clearance in narrow spaces
• 72-tooth mechanism gives 5° swing arc for tight-angle work
• Available in both 1/4" and 3/8" drive sizes for versatility

What sockets and accessories are included to cover common jobs?

The 71-piece configuration includes an assortment of sockets, extensions, adapters, and drive tools sized for everyday automotive and home projects. The combination of 1/4" and 3/8" drive components lets you choose the right balance of torque and accessibility for most bolts and nuts.

• Full set of standard and metric sockets across 1/4" and 3/8" drives
• Extensions and adapters to reach recessed fasteners
• Drive tools and accessories to expand functionality as needs grow

Is this set durable and easy to maintain?

Tools in the set are finished with polished chrome to resist rust and simplify cleaning after use. Construction conforms to ASME specifications, which indicates consistent manufacturing tolerance and strength appropriate for common mechanical tasks.

• Polished chrome finish for corrosion resistance and easy wipe-down

How does the VERSASTACK compatibility help organize my workspace?
