If an older forum post or build document brought you to the retired RocketMaterials shear-pin resource, the surviving report is linked here.
Read the historical report
Open the preserved RocketMaterials shear-pin test report (PDF). The report identifies an update of August 19, 2004 and retains the original resource URL in its page footers.
What the record contains
The report describes specific test fixtures, nylon screw specimens, peak loads and variation between trials. It discusses how the fixture and pin arrangement affected the measurements. It also includes limited cardboard-fixture results and tests using fork tines.
Use the results in context
These are historical specimen measurements. They are not a current product certification or a universal load rating for every screw, tube or joint. Read the original method and limitations alongside the tables, and seek current manufacturer guidance for your actual hardware.
The current RocketMaterials editorial site did not perform these legacy tests. This page provides access to the surviving record; it does not republish the full dataset.
