The Challenge

A crew working with a harvester contacted Big Bolt. Some of the bolts on the machine kept bending. The broken bolts were costing the crew time and money, so they needed to know why it was happening.

The Investigation

Big Bolt asked for samples of the broken bolts. An investigation determined that the bolts were failing in the threaded section. Big Bolt concluded that the threaded section of the bolt needed to be adjusted.

The dimensions of the bolts were incorrect. The threads were in the shear plane and causing this type of failure to occur. Threads in the shear plane reduce the bolt design’s shear capacity.

The Strategy

Big Bolt devised a plan to keep the bolts from failing, Their experts determined that shortening the threaded section would make the bolt stronger.

The Solution

Shortening the threaded section of the bolt worked. It strengthened the shear plane connection. And because Big Bolt always has a full supply of blanks, the new bolts were manufactured and shipped in about a week.
