A multi-bit driver apparatus containing a driver housing, a plurality of rotary drivers, and a rotary driver mechanism is presented. The driver housing contains a driver receiving cavity, and a plurality of rotary apertures. The plurality of rotary each contains a bit shaft, and a bit mounting aperture. The driver receiving cavity is positioned within the driver housing. The plurality of rotary apertures is distributed about the driver housing. The plurality of rotary drivers is positioned within the driver receiving cavity. The bit shaft is rotatably connected along the plurality of rotary apertures. The plurality of rotary drivers is rotatably engaged to each other through the rotary driver mechanism, where the plurality of rotary drivers is configured to rotate in tandem with each other. The bit mounting aperture traverses through the bit shaft.

An apparatus and method for detecting structural and material defects in a fastener driven during a manufacturing process includes a driving tool capable of recording an angle-torque trace during the driving of the fastener and a machine learning engine operably connected to the driving tool for analyzing the recorded angle-torque trace. The machine learning engine can be provided with a number of sample angle-torque traces from sample fasteners and can self-determine a stored trace including tolerances for acceptable angle-torque trace data from the samples in an unsupervised learning process or protocol without the need for defined anomalous and non-anomalous samples being provided to the machine learning engine. Using the self-defined stored trace and acceptable tolerances, the machine learning engine can analyze attributes of subsequently recorded angle-torque traces to ascertain whether the attributes of the recorded angle-torque traces indicate anomalies within the fastener identified by the recorded trace.

An improved multi-bolt and nut torque wrench for installing and removing bolts or nuts from flanged joints or the like which includes a plurality of torque stations having a plurality of high torque wrenches for engaging the heads of the bolts or nuts during a high torque phase of removal or installation; a plurality of low-torque motors operatively engaged with the wrenches for rotating the bolts or nuts during the low torque phase of removal or installation; a source of hydraulic fluid for driving the low-torque motors during the low-torque phase, and driving the high-torque wrenches during the high torque phase; and a mechanism for switching between the two phases depending on the torque needed.

Fasteners, drivers, punches, fastener systems, and methods of making fasteners, drivers, punches, and fastener systems are disclosed herein. The fasteners, drivers, punches, and fastener systems include, in one example, stabilizing ribs and corresponding recesses.

Systems and methods of operating power tools. The method includes receiving a command to start a recording mode at a first electronic processor of a first power tool, and receiving at the first electronic processor, a measured parameter from a sensor of the first power tool while a first motor of the first power tool is operating. The method also includes generating a recorded motor parameter by recording the measured parameter, on a first memory of the first power tool, when the first power tool operates in the recording mode, and transmitting, with a first transceiver of the first power tool, the recorded motor parameter. The method further includes receiving the recorded motor parameter at an external device, transmitting the recorded motor parameter to a second power tool via the external device, and receiving the recorded motor parameter via a second transceiver of the second power tool.
