Across
  1. 2. The connection option that arrives with a wrench and leaves with a checklist.
  2. 4. The twisting force that turns “snug” into “serious.”
  3. 5. The connection that says, “We are now one piece forever.”
  4. 7. The spiral part that looks important, but isn’t always where the shear should be.
  5. 8. The total thickness of the steel “sandwich” being clamped together.
  6. 10. The smooth part of the bolt that does the hard work quietly.
  7. 11. The weld that looks like a tiny metal triangle doing a big job.
Down
  1. 1. The weld that needs prep work first—like steel getting ready for surgery.
  2. 3. When a connection refuses to rotate freely and decides to resist bending.
  3. 6. The flat metal sidekick that spreads pressure and protects the surface.
  4. 9. The “no drama” connection—strong, but it lets the beam rotate.
  5. 10. The thing you don’t want happening when the structure starts shaking.
