Sunex Tools 3580 80-Piece 3/8 Inch Drive Master Impact Socket Set

The 3580 is a genuine impact socket set. The sockets are made from chrome-molybdenum (Cr-Mo) steel, the alloy standard for impact use, and are listed by Sunex as compatible with both impact drivers and impact wrenches. Cr-Mo sockets have the toughness to absorb rapid high-torque impulses without shattering, unlike standard chrome-vanadium hand sockets.

Yes. The metric range runs from 8 mm to 19 mm continuously, covering 10 mm in shallow, deep, and universal (wobble) configurations. All three metric variants are included for every size in the range.

Both are 3/8-in drive Cr-Mo impact socket sets. The 3342 is a 42-piece set covering SAE and metric in standard and deep variants only. The 3580 is the 80-piece master set that adds universal (wobble) sockets in both SAE and metric, plus a full complement of Torx (T20-T55) and E-Torx (E5-E16) sockets that the 3342 does not include. The 3580 is the more comprehensive choice for work that involves star fasteners common on European vehicles and modern drivetrains.

Yes. Sunex Tools specifies a lifetime warranty on the 3580, as listed in the product specifications. The lifetime warranty is a documented manufacturer commitment that extends the useful life of the set through repair or replacement rather than disposal.

The 3580 is a 3/8-in drive set. For typical lug nuts and larger suspension fasteners (which commonly require 1/2-in drive for the higher torque capacity), a 1/2-in drive set is the appropriate choice. The 3580 handles the majority of engine-bay, brake, and interior fasteners that fall in the 3/8-in drive range, but buyers who frequently work on wheels or suspension components benefit from adding a 1/2-in drive set.
