Definition: "A spanner wrench is a specialized tool designed to grip and turn fasteners that have slots, holes, notches, or protrusions around their circumference—features that standard wrenches can't handle effectively." [credit MS Copilot]
"Common Uses of a Spanner Wrench:
Plumbing & HVAC: Tightening or loosening gland nuts, pipe fittings, and retaining rings without damaging soft metals.
Machinery Maintenance: Adjusting threaded collars, locknuts, and round nuts on industrial equipment.
Bicycle & Motorcycle Repair: Setting preload on suspension systems or securing components with slotted nuts.
Camera & Optical Equipment: Handling delicate retaining rings on lenses or precision instruments."
