GEARWRENCH 84925N 29-Piece 3/8-Inch Drive Metric Impact Socket Set

The GEARWRENCH 84925N 29-Piece 3/8-Inch Drive Impact Socket Set is an industrial fastener driving kit engineered for high-torque pneumatic impact wrench service, suspension component disassembly, engine repair, and heavy machinery maintenance. Manufactured from heat-treated chrome molybdenum alloy steel (Cr-Mo) with a corrosion-resistant black oxide finish, this 6-point metric collection spans sizes from 8 mm to 22 mm across both standard and deep well socket profiles. Outfitted with off-corner loading geometry to prevent bolt head rounding, dual laser-etched and hard-stamped size markings, a 3/8-inch drive universal joint, and a blow-molded carrying case, this set meets or exceeds all ASME strength standards.

Best Used For:

  • Automotive Suspension & Brake Service: Removing stubborn caliper bracket bolts, strut mount nuts, and control arm fasteners with high-torque impact wrenches.
  • Engine Bay & Transmission Maintenance: Reaching recessed metric fasteners in cramped engine compartments using deep-well sockets and the included universal joint.
  • Industrial Equipment & Machinery Repair: Driving 8 mm to 22 mm metric bolts on commercial plant machinery without stripping worn fastener heads.

Key Performance & Safety Features

  • Chrome Molybdenum (Cr-Mo) Alloy Steel: Premium impact-grade steel formulation absorbs heavy pneumatic rotational shock without cracking or shattering.
  • Anti-Rounding Off-Corner Loading Geometry: Shifts contact force to the flat sides of hex fasteners rather than the corners to prevent stripping.
  • Protective Black Oxide Coating: Chemical conversion finish shields high-stress alloy steel against corrosion, rust, and shop fluid exposure.
  • Dual High-Visibility Size Markings: Combines bold laser-etched text for quick selection with permanent hard-stamped numbers for permanent legibility.
  • High-Flex 3/8-Inch Drive Universal Joint: Swivel adapter articulates at off-axis angles to access awkward fasteners inside confined chassis spaces.
  • Custom Blow-Molded Storage Organizer: Heavy-duty molded organizer case locks each socket into dedicated size-marked slots for easy jobsite transport.

What's Included

  • (14) 3/8 In. Drive 6-Point Metric Standard Impact Sockets (8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, 16mm, 17mm, 18mm, 19mm, 21mm, 22mm)
  • (14) 3/8 In. Drive 6-Point Metric Deep Impact Sockets (8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, 16mm, 17mm, 18mm, 19mm, 21mm, 22mm)
  • (1) 3/8 In. Drive Universal Joint Adapter
  • (1) Hard Shell Blow-Molded Storage Case
