SKU CH-DBHN-2Z56B

A 55 mm single-end open wrench with a 15-degree offset head and 16 23/32 in overall length

  • Professional-grade Facom reliability for heavy-duty fastening
  • 55 mm metric opening fits large industrial bolts
  • 15-degree offset head improves access in tight spaces
  • 16 23/32 in overall length provides strong leverage
  • Carbon steel with black oxide finish resists corrosion

55 mm Open-End Wrench

The Facom FM-45.55 is a single-ended metric wrench sized at 55 mm with a 15-degree head angle. Forged from carbon steel, it carries a black oxide finish and measures 16 3/4 inches overall with a 5/8 inch head thickness. The one-piece rounded design suits heavy-duty fastening tasks.

Suited to large fastener work

Mechanics and maintenance crews needing a 55 mm opening on substantial bolts will find the length and leverage appropriate. The wrench is not insulated, so it must not be used on live electrical equipment. Buyers requiring a double-ended profile or a smaller head size should look elsewhere.

55 mm capacity and leverage

The 55 mm jaw fits corresponding nuts and bolts directly, while the 16 3/4 inch handle provides mechanical advantage for high-torque applications. The 5/8 inch head thickness resists deformation under load. There is no second opening, so a different wrench is needed for any other fastener size.

The 55 mm open end engages metric nuts and bolts with a 55 mm across-flats dimension.

Will the 16 3/4 in length clear obstacles that shorter wrenches cannot?

The 16 3/4 in overall length provides extra reach for deep or recessed 55 mm fasteners.

How can I confirm the 15 degree offset is correct after I start using it?
