Abstract
A fastener used to secure an electrical conductor includes a head, a shaft, and a pressure pad. The head has an inner surface for receiving a drive tool. The shaft has an outer surface including a threaded portion. The pressure pad can include a surface feature. The pressure pad can also be releasably, rotationally-fixed to the shaft through a breakaway portion.

A fastener comprising:
- a head having an inner surface including a first socket for receiving a drive tool;
- a shaft having an outer surface including a threaded portion;
- a shearable section positioned between the head and the shaft having a first torque limit;
- and
- a pressure pad having a surface feature and a breakaway portion with a second torque limit connecting the pressure pad to the shaft.
2 more elements
An electrical connector comprising:
- a body having a first aperture for receiving a conductor and a second aperture having a thread for receiving a fastener;
- and
- a fastener positioned in the second aperture including a head having an inner surface including a first socket for receiving a drive tool, a shaft having an outer surface including a threaded portion, a shearable section positioned between the head and the shaft having a first torque limit, and a pressure pad having a surface feature and a breakaway portion with a second torque limit connecting the pressure pad to the shaft.
A method of securing a conductor to an electrical connector comprising:
- placing a conductor into a first aperture of an electrical connector having a fastener positioned in a second aperture, the fastener including a head having an inner surface including a first socket for receiving a drive tool, a shaft having a threaded portion, a shearable section positioned between the head and the shaft having a first torque limit, and a pressure pad having a surface feature and a breakaway portion with a second torque limit less than the first torque limit rotatably fixing the pressure pad to the shaft;
- rotating the fastener until the second torque limit is reached, fracturing the breakaway portion and allowing the pressure pad to rotate with respect to the shaft;
- and
- rotating the fastener until the first torque limit is reached, separating the head from the shaft.
