Description

20-GAUGE STEEL • 133-PIECE METRIC SET • STANDARD + DEEP SOCKETS • KEY + COMBO LOCK

For the homeowner who wants the metric bases fully covered — not a starter kit.

Most affordable tool sets give you the common sizes and leave gaps you don't discover until you're mid-job. You've got the 10mm and the 13mm, but not the 22mm the job actually calls for — or you've got standard sockets but nothing deep enough to reach the fastener. The BOXO USA 133-Piece Metric set is built to close those gaps: broad metric coverage, standard and deep sockets in both common drives, and the hex and torx keys a modern vehicle needs — so the size you reach for is in the tray.

This is a complete working set, not a blister-pack starter. It's the kit you buy so you stop making a parts-store run every time a job needs a size you don't have.

Why it earns a spot in your shop:

  • The sizes that are never in the small set. 1/4" and 3/8" drive sockets running the full common metric range, in both standard and deep — plus a 14-piece combination wrench set — so the metric size you need is actually there.
  • Fasteners a shallow socket can't reach. Deep sockets in both drives get down over studs and recessed bolts, right alongside the standard sockets for everything else.
  • Fine ratcheting in tight quarters. 1/4" and 3/8" drive 90-tooth ratchets turn a fastener on just a few degrees of swing — the difference between progress and skinned knuckles in a packed engine bay.
  • The modern-vehicle fasteners a basic set skips. A 9-piece ball hex set, a 9-piece torx key set, and a 10-piece anti-tamper bit set with adapter — the stuff today's cars and equipment actually use.
  • Wrenches that slip and round off bolts. Smooth open ends, 12-point box ends with positive grip, and a 15° offset for clearance — with the size marked on both sides so you grab the right one fast.
  • Tools that rust and look rough. Professional-grade tools with a mirror chrome finish that resists corrosion and wipes clean.
  • Tools shifting around and going missing. Every tool sits in a molded EVA foam tray, so nothing rattles loose and one look tells you if a piece is gone.
  • A box that won't keep your investment safe. Heavy-duty 20-gauge steel with three comfortable handles, ball-bearing slides, three drawers, a deep top compartment, and a key lock plus resettable digit combination.

Broad, organized, and built to last — the metric set that has what the job needs, right when you need it.
