VEVOR 3/8" Drive Impact Socket Set — 15-Piece Metric (8–22mm), 6-Point Cr-Mo

You're mid-job and the fastener won't budge. It's metric, it's tight, and your 1/2" drive is too big to fit the angle. That's exactly the gap a 3/8" drive set fills — strong enough to handle stubborn underhood bolts, small enough to actually reach them.

This 15-piece set covers 8mm through 22mm in a continuous run — no gaps in the common sizes you'll actually reach for. Sockets are Cr-Mo alloy steel, vacuum heat-treated to HRC 42–48 hardness, and built to handle impact torque without cracking. The 6-point design grips the flats of a fastener instead of the corners, which matters when you're breaking loose something that's been corroded on for a decade.

What's in the set:

• 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, 16mm, 17mm, 18mm, 19mm, 20mm, 21mm, 22mm
• All deep well, 3/8" drive
• Plastic storage case with molded slots

Good for:

• Underhood work — valve covers, intake manifolds, sensor housings
• Suspension components where a 1/2" drive won't fit
• Wheel bearing nuts, caliper bolts, hub hardware
• General metric fasteners on imported vehicles

Not for:

• SAE fasteners — this is metric only
• Heavy torque applications above what 3/8" drive is rated for (use 1/2" drive for lug nuts)
• Fine finish work where chrome polish matters

A full 8–22mm run in Cr-Mo steel is a straightforward buy. Not the fanciest socket set on the market. Just a solid, complete metric set that covers underhood work without a gap in the lineup.
