A fixed adjustable wrench. The fixed adjustable wrench includes a handle having a fixed jaw and an adjustable jaw forming a gap therebetween. The adjustable jaw is slidable along a shoulder and is adapted to cooperate with the fixed jaw to secure an object within the gap. An engagement member having a first set of teeth is configured to selectively interlock with a second set of teeth of the adjustable jaw. A second end of the engagement member is operably connected to a lever that is selectively moveable between an engagement position and a disengagement position. In the engagement position, the engagement member is coupled to the adjustable jaw via an interlocking of the first set of teeth and the second set of teeth. In the disengagement position, the engagement member is disengaged from the adjustable jaw allowing selective positioning of the adjustable jaw.

An example wrench is provided. The example wrench includes a first jaw having a first jaw engaging surface configured to engage a first side of a fastener and a second jaw having a second jaw engaging surface configured to engage a second side of a fastener. A first plane defined by the first jaw engaging surface may intersect with a second plane defined by the second jaw engaging surface at an engagement angle. The engagement angle may be an acute angle.

A wrench has a first segment and a second segment pivotally coupled together. The second segment is selectively positionable at various fixed pivotal positions relative to the first segment. The first and the second segments engage with a locking device. The first segment has a first joining end forming a first positioning surface and a second positioning surface. The locking device includes a catch selectively engagable and disengagable from the first and the second positioning surfaces. The catch has a body section abutting against the first positioning surface in a direction radial to the axis of rotation when the first segment is at a first fixed pivotal position relative to the second segment. The first body section is abutted against the second positioning surface in a direction radial to the axis of rotation when the first segment is at a second fixed pivotal position relative to the second segment.

A two jaw adjustable wrench having two opposing jaws that adjust inward and outward, one jaw having a left hand thread and the opposing jaw having a right hand thread for ease of adjustment. The user rotates the central knurled wheel in either a clockwise or counterclockwise rotation. The direction of rotation influences the opposing jaws to move inward or outward for various fastener size adjustments.

Opposite end of the ratchet wrench has a universally adaptable and slideable ratchet wrench for accepting universal ¼″ hexagon tool bits such as a #1 and #2 Phillips or slotted screwdriver bits of various sizes. Both tool ends are easily retractable and extendable by sliding either tool forward for use and or retractable when not in use.

The Adjustable and Ratchet Wrench's upper housing half provides two pocket-slots to store the Phillip's #1 and #2 screwdriver attachment and a #1 & #2 slotted screwdriver attachment.
