Abstract: A compound wrench apparatus includes a bolt shaft which includes threads. A bolt head is connected to the bolt shaft at a proximal end of the shaft. A first wrench assembly is engaged by the threads and is proximal to the proximal end of the shaft. A second wrench assembly is engaged by the threads of the shaft and is distal to the first wrench assembly. The first wrench assembly includes a threaded lock nut received on the shaft. A retention bracket is received on the shaft and is located between the lock nut and the implement-receiver. A first wrench member is provided, and a first pivot is connected between the retention bracket and the first wrench member. A brace is connected between the first wrench member and the retention bracket. A first bracket portion of the retention bracket includes a slot which receives the shaft and is oriented perpendicularly to the longitudinal axis. The second wrench assembly includes a threaded carriage received on the shaft.
