GEARWRENCH 84916N 44-Piece 3/8" Drive 6-Point SAE & Metric Impact Socket Set

The GEARWRENCH 84916N 44-piece 3/8-inch drive 6-point impact socket set fastens standard SAE and metric hex hardware across automotive suspension assemblies, commercial fleet machinery, and heavy industrial plant equipment. Forged from high-strength chrome molybdenum (Cr-Mo) alloy steel treated with a corrosion-resistant black oxide coating, these standard and deep sockets feature an off-corner loading broach that applies rotational force to fastener flats to prevent corner rounding. Outfitted with high-visibility dual laser-etched and roll-stamped size markings, two impact extension bars (3-inch and 6-inch), a 3/8-inch universal flex joint, and a rugged blow-molded case, it equips professional automotive technicians, diesel fleet specialists, and millwrights with ASME B107.2-compliant high-torque fastening performance.

Best Used For:

  • Automotive Chassis and Brake Service: Removing stubborn suspension bolts, caliper brackets, and steering linkage fasteners with pneumatic or cordless impact wrenches.
  • Diesel Engine and Drivetrain Maintenance: Slicing down through recessed engine bay hardware and deep transmission bellhousing studs using deep-well sockets and extension bars.
  • Industrial Machinery Assembly and Rigging: Torquing heavy structural machine mounts and anchor bolts across plant floors without stripping fastener heads.

Key Performance & Safety Features

  • Forged Chrome Molybdenum (Cr-Mo) Alloy Steel: Industrial impact-grade metallurgy absorbs continuous torque shockwaves from high-output pneumatic and cordless impact wrenches.
  • Off-Corner Loading Broach Architecture: Directs rotational force across the flat surfaces of hex hardware, preventing fastener damage and stripped corners.
  • Parallel Neck-Down Geometry: Slender neck-down profile on smaller metric sizes (8mm, 9mm, 10mm, 11mm) provides enhanced clearance into tight, recessed fastener wells.
  • Permanent Dual Size Markings: Combines high-contrast laser markings for instant identification with secondary stamped hard impressions that survive abrasive shop wear.
  • Corrosion-Resistant Black Oxide Surface: Industrial chemical conversion finish seals alloy steel against rust, shop solvents, and hydraulic fluids.
  • Complete Impact Drive Extension Package: Includes a 3-inch extension, 6-inch extension, and 3/8-inch universal impact knuckle for off-axis angle access.

Pro-Tip: When using the impact universal joint on stubborn suspension hardware, keep your operating angle under 30 degrees; this maintains maximum torque transfer from your 3/8-inch impact anvil directly into the fastener while protecting the swivel pin from premature fatigue.
