DEWALT Mechanics Tool Set DWMT45402 131 Piece Socket Kit (Chrome Vanadium Steel 72 Tooth Ratchet SAE Metric ToughSystem Tray Automotive Fastening)

Navigate Cramped Engine Bays and Secure High-Torque Fasteners Natively inside a Modular Workspace Container Array

The DEWALT DWMT45402 131-Piece Mechanics Tool Set is a professional-grade 1/4-inch and 3/8-inch drive socket and fastening system engineered for automotive maintenance and workshop chassis repair operations. Forged from premium-grade Chrome Vanadium steel with a corrosion-resistant full-polish chrome finish, this comprehensive set utilizes high-maneuverability 72-tooth ratchets that deliver a tight 5-degree arc swing to turn hardware in highly restricted engine compartments. Outfitted inside two modular ToughSystem® 2.0 shallow trays with custom molded inserts and lids, this dual SAE and Metric utility array coordinates layout workflows seamlessly.

Best Used For:

• Automotive Engine Overhauls: Reaching and turning deeply recessed oil pan bolts, manifold nuts, and ignition block brackets inside compact modern vehicle engine compartments.
• Chassis Suspension Assembly: Driving heavy-duty fractional SAE and metric hardware connections across undercarriage steering rods, sway links, and brake caliper mounts.
• Mobile Site Operations: Transporting structured tool configurations safely across dynamic service calls by packing the modular layout trays straight into rolling equipment cases.

Key Performance & Safety Features

• 5-Degree Arc Swing Maneuverability: Precision 72-tooth gear mechanism drives high-torque fastening inside confined corridors where normal tools bind entirely.
• Forged Chrome Vanadium Core: Heavy-duty cold-drawn structural steel alloy provides long-term resistance against rotational socket shearing and wall fracturing under load.
• Full-Polish Anti-Corrosion Skin: Smooth mirror finish repels garage moisture, cutting oils, and synthetic grease while enabling immediate jobsite cleaning passes.
• Hard-Stamped Size Identification: High-contrast alphanumeric scale markings stamped directly onto socket outer bodies prevent measurement layout tracking fade.
• Universal ToughSystem 2.0 Staging: Interlocking shallow modular trays feature structural component nests and transparent safety lids to verify parts inventory instantly.

Technical Specifications

PRO-TIP: When seating thin-walled 1/4-inch or 3/8-inch drive sockets inside greasy engine blocks, wipe away surface scale before applying the ratchet handle. Aligning the 6-point internal socket flats square and dead-flush over the hardware head maximizes the full load-bearing footprint of the Chrome Vanadium alloy, stopping high-torque slips and keeping tool faces intact.
