A wrench system provides for resiliently holding a nut periphery between opposed jaws and holding washer axially of the nut between arms at right angles to the jaws and with the jaws between the arms; adjustment of inter-jaw spacing is provided by a first sliding member carrying past an extended portion of each jaw at an inclined angle thereto respective provisions urging it inward toward the other jaw or outward away from it, depending on direction of sliding; convolutions in the extended portions of the jaws provided for step setting of jaw spacing; a second sliding member carries the washer holding arms into position for washer holding in alignment with a nut held by the wrench system, or away from that position to provide clear access for nut loading; a headed screw fixes the first and second sliding members in selected relation to the handle.

1. In a wrench system having means for adjustably holding a nut, means for holding a washer in alignment with the nut for attachment of the washer and nut on a fastener such as a bolt, and a longitudinally extending handle portion, the improvement comprising: the means for adjustably holding a nut including: first and second jaws, means resiliently spacing the first and second jaws relative to each other; said means for holding a washer including: at least a first arm, means for biasing the first arm toward said first and second jaws, said first arm having a slotted end for receiving a said fastener therein, said means for resiliently spacing the first and second jaws relative to each other comprising: said first and second jaws having respective resilient portions thereof extending to and affixed to said longitudinally extending handle portion, a first member slidable relative to said longitudinally extending handle portion, the first member having a protrusion between said respective resilient portions, a respective part of the first member outboard each respective resilient portion; a second member slidable relative to said longitudinally extending handle portion, said means for biasing the first arm toward said first and second jaws, including said first arm being resilient and affixed to said second member; means for fixing the slidable position of said first member and of said second member relative to said longitudinally extending handle portion, the longitudinally extending handle portion substantially surrounding the first member, the second member substantially surrounding the longitudinally extending handle portion, and the means for fixing the slidable position being a headed screw extending through respective slots in said second member and said longitudinally extending handle portion and threaded into said first member. 2. In a wrench system having means for adjustably holding a nut, means for holding a washer in alignment with the nut for attachment of the washer and nut on a fastener such as a bolt, and a longitudinally extending handle portion, the improvement comprising: the means for adjustably holding a nut including: first and second jaws, means resiliently spacing the first and second jaws relative to each other; said means for holding a washer including: at least a first arm, means for biasing the first arm toward said first and second jaws, said first arm having a slotted end for receiving a said fastener therein, said means for resiliently spacing the first and second jaws relative to each other comprising: said first and second jaws having respective resilient portions thereof extending to and affixed to said longitudinally extending handle portion, a first member slidable relative to said longitudinally extending handle portion, the first member having a protrusion between said respective resilient portions, a respective part of the first member outboard each respective resilient portion; said resilient portion affixation being to respective sides of said longitudinally extending handle portion, and the distance between said respective parts of the first member outboard each respective resilient portion being less than the effective distance between said affixations of said resilient portions to said respective sides of the longitudinally extending handle portion whereby said sliding of the first member relative to the longitudinally extending handle portion adjusts said spacing between the jaws. 3. In a system as recited in claim 2, and means for providing step-settings in said spacing adjustment, comprising said resilient portions being convoluted adjacent said first member parts. 4. In a system as recited in claim 2, said means for resiliently spacing being means for symmettrically resiliently spacing. 5. In a wrench system having means for adjustably holding a nut, means for holding a washer in alignment with the nut for attachment of the washer and nut on a fastener such as a bolt, and a longitudinally extending handle portion, the improvement comprising: the means for adjustably holding a nut including: first and second jaws, means resiliently spacing the first and second jaws relative to each other; said means for holding a washer including: at least a first arm, means for biasing the first arm toward said first and second jaws, said first arm having a slotted end for receiving a said fastener therein, said means for resiliently spacing the first and second jaws relative to each other comprising: said first and second jaws having respective resilient portions thereof extending to and affixed to said longitudinally extending handle portion, a first member slidable relative to said longitudinally extending handle portion, the first member having a protrusion between said respective resilient portions, a respective part of the first member outboard each respective resilient portion, said first member protrusion having an incline adjacent each said respective first member part in a location for bearing on a respective resilient portion. 6. In a wrench system having means for adjustably holding a nut, means for holding a washer in alignment with the nut for attachment of the washer and nut on a fastener such as a bolt, and a longitudinally extending handle portion, the improvement comprising: the means for adjustably holding a nut including: first and second jaws, means resiliently spacing the first and second jaws relative to each other; said means for holding a washer including: at least a first arm, means for biasing the first arm toward said first and second jaws, said first arm having a slotted end for receiving a said fastener therein, said means for resiliently spacing the first and second jaws relative to each other comprising: said first and second jaws having respective resilient portions thereof extending to and affixed to said longitudinally extending handle portion, a first member slidable relative to said longitudinally extending handle portion, the first member having a protrusion between said respective resilient portions, a respective part of the first member outboard each respective resilient portion, a second member slidable relative to said longitudinally extending handle portion, said means for biasing the first arm toward said first and second jaws including said first arm being resilient and affixed to said second member, and a second said arm, opposed to the first arm and fixed on said second member, with said first and second jaws between the first arm and the second arm. 7. In a wrench system having means for adjustably holding a nut, means for holding a washer in alignment with the nut for attachment of the washer and nut on a fastener such as a bolt and a longitudinally extending handle portion, the improvement comprising: the means for adjustably holding a nut including: first and second jaws, means slidable on the longitudinally extending handle portion for resiliently spacing the first and second jaws relative to each other; said means for holding a washer including first and second arms at right angles to said first and second jaws, means for biasing said first and second arms towards said first and second jaws, each of said first and second arms being offset inwardly, and having a respective slotted end therein for receiving a said fastener therein. 8. In a wrench system as recited in claim 7, said means for holding a washer slidable on the longitudinally extending handle portion, and means on the longitudinally extending handle portion for simultaneously tightening in slidable position said means for resiliently spacing and means for holding a washer.
