  • Heat-treated chrome vanadium steel resists rounding

Steelman 78533 15-Piece Metric Set

This new Steelman 78533 set provides fifteen metric combination wrenches for professional service technicians and serious DIY mechanics. Each wrench is constructed from heat-treated chrome vanadium steel alloy with a mirror-polish chrome plating for rust resistance. Size callouts are stamped vertically and horizontally on both sides for quick identification. The open and box ends both feature a 15-degree offset for improved access in tight spaces.

Suited for metric fastener work up to 21 mm

These wrenches meet or exceed ASME and ANSI torque standards, making them reliable for daily garage use. The 15-degree offset on both ends helps reach fasteners where clearance is limited. Buyers who need imperial sizes, a larger piece count, or sizes beyond 21 mm should look at other sets. The product carries a California Proposition 65 warning for chemicals known to cause cancer and birth defects.

15-piece metric range from 7 mm to 21 mm

The set covers 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, and 21 mm fasteners. This specific range decides whether the kit matches the hardware you work on most often. If your regular jobs require sizes outside this spread, a different combination will be necessary.

Questions about this item

How much heat or power does the 78533 wrench set generate during all-day use?

These are hand tools with no motor or electronics, so they produce no heat and draw no power during extended use.

What must I already own for the 78533 set to work?

Only the fasteners you intend to turn — the 6-point box and open ends fit standard metric nuts and bolts from 7 mm through 21 mm.

Will the 78533 wrenches clear older fasteners with rounded or worn corners?

The 6-point box end and 15-degree offset give better grip on worn heads while providing finger clearance in tight spots.
