GEARWRENCH 82554 6-Piece 3/8-Inch Drive Long Metric Hex Bit Socket Set

The GEARWRENCH 82554 6-Piece 3/8-Inch Drive Long Metric Hex Bit Socket Set is an extended-reach driver tool collection engineered for accessing deeply recessed internal hex fasteners in automotive engine bays, heavy machinery housings, and hydraulic valve assemblies. Utilizing precision-machined S2 tool steel insert bits with a protective black oxide coating, these extended bits resist cam-out, bit wear, and high rotational torque loads across sizes ranging from 4 mm to 10 mm. Outfitted with heat-treated alloy steel socket bases featuring full polish chrome plating, a distinct metric knurled identification ring, permanent hard-stamped size markings, and a metal storage rail, this 1-3/100 pound set meets or exceeds all ASME performance standards.

Best Used For:

  • Automotive Engine & Intake Manifold Service: Reaching deeply recessed internal hex bolts on intake manifolds, valve covers, and brake caliper slides.
  • Industrial Machinery Housing Maintenance: Servicing recessed metric socket head cap screws inside tight gearbox housings and hydraulic pumps.
  • Heavy Equipment Hydraulic Valve Fastening: Applying precise torque to recessed 4 mm through 10 mm hex fasteners in cramped mechanical bays.

Key Performance & Safety Features

  • Extended Long-Reach Bit Profile: Extra bit length bypasses structural obstructions to access deeply sunken socket head cap screws.
  • High-Tolerance S2 Tool Steel Bits: Industrial-grade S2 steel inserts deliver superior hardness and dimensional accuracy to prevent fastener stripping.
  • Knurled Metric Base Identification Ring: Distinctive knurled pattern around the socket base allows instant visual differentiation from SAE sockets.
  • Full Polish Chrome Alloy Steel Bases: Heat-treated alloy steel bases resist chemical corrosion, surface rust, and wipe clean easily after greasy jobs.
  • Black Oxide Protective Bit Finish: Chemical conversion coating shields the high-stress steel bit shaft from rust and mechanical abrasion.
  • Permanent Hard-Stamped Size Markings: Roll-stamped sizing on socket walls ensures long-lasting legibility even after continuous shop wear.

What's Included

  • (6) 3/8 In. Drive Long Metric Hex Bit Sockets (4mm, 5mm, 6mm, 7mm, 8mm, 10mm)
  • (1) Aluminum Socket Storage Organizer Rail
