Material moving system

A pin assembly for a chain of a material moving system comprising:

• a pin having a first end and a second end, the first end comprising a threaded portion extending to a guide region having a reduced cross-section compared to the threaded portion, the threaded portion being at least partially modified during fabrication of the pin, the guide region extending to a transition region of increasing cross-section with respect to the guide region from the first end toward the second end, the transition region terminating at a shoulder;
• a fastener configured to engage the threaded portion during construction of the chain;
• in response to an opening of a first chain link being directed over the first end of the pin during construction of the chain, the opening having a cross-section greater than a cross-section of the guide region and less than or equal to a cross-section of the transition region, the fastener urges the first chain link to a position over the transition region, forming a compression fit between the opening and the transition region in response to a predetermined torque applied to the fastener;
• and
• wherein during application of the predetermined torque to the fastener, the fastener threadedly engaging the threaded portion of the pin, at least a threaded segment of the fastener is damaged, substantially limiting reuse of the fastener after the fastener has been disassembled from the threaded portion of the pin.
