For a period of time in 2021 the Go Direct® Structures & Materials Tester (GDX-VSMT) was shipped without the rivets that hold the endcaps onto the 8020 extruded aluminum supports. If you are assembling your Structures Tester and find these are missing, email support@vernier.com and request that the “end cap rivets” be sent to you.
