1. A shear coupling for connecting downhole components of a well string, the shear coupling comprising:
first and second coupling members driveably engageable with each other, each of the first and second coupling members having an axial bore formed therethrough, a shoulder being formed on the second coupling member within the axial bore, the axial bore of at least one of the first and second coupling members having an internally threaded portion; and
a shearable connecting member having a first end and a second end, the shearable connecting member disposably receivable within the internally threaded portion of the axial bore of at least one of the first and second coupling members, the shearable connecting member being radially supportable by the internally threaded portion of the axial bore and configurable to operatively connect the first and second coupling members,
wherein the first end of the shearable connecting member comprises a body having a circumferential flange formed thereon that is axially engageable with the shoulder.
