Like a ratchet, we have stepped back to move further forward.

The invention concerns a ratchet spanner comprising a chuck (3) which is rotatably disposed in the annular or jaw-like spanner head (1) and is supported such that it can slide axially on steps at the ends of the cylindrical head opening.

Ratchet wrenches are provided that allow for drive on both the forward and return strokes of the ratchet handle.

A method of assembling and using the low profile ratchet wrench (10) is described.

A low profile ratchet wrench (10) has an opening (22, 26, 28) formed through the head (16) of the wrench (10).

A ratchet wrench has a drive-stud element with a drive stud at a first end and a drive recess at a second end.

An improved socket wrench (300) is provided which includes a first pawl (318) sliding on a first slide surface (312) and a second pawl (320) sliding on a second slide surface (314).

The final revolutions when placing the implants exceeded the value of 32 Ncm and were performed by hand.

A reversible and a bidirectional ratcheting wrench that transfers multiple torque power from the handle (20, 120) to a nut, or a standard (71) or special socket (68), by use of flat gears.
