Bolting — Snug-Tight Adequacy Check
Whether a joint may remain snug-tight or requires pretension per the RCSC decision rules.
Most bearing-type joints need only snug-tight — full ironworker effort on a spud wrench. Pretensioning everything wastes hours and tool wear; the RCSC table of WHERE pretension is required is the checklist this tool encodes.
Formula
Note: Erection-planning estimate only. Member weights, connection capacities and tolerances for execution must come from the issued drawings, the EOR and the erection engineer — never from a generic calculator.

About Bolting — Snug-Tight Adequacy Check
Bolting — Snug-Tight Adequacy Check computes the governing relationship RCSC: pretension if slip-critical, direct tension, fatigue/reversal, or spec-listed cases live as you type. Most bearing-type joints need only snug-tight — full ironworker effort on a spud wrench. Pretensioning everything wastes hours and tool wear; the RCSC table of WHERE pretension is required is the checklist this tool encodes. Defaults are pre-filled with realistic values for this exact scenario, and the worked example substitutes your numbers step by step so the math is never a black box.
How to use Bolting — Snug-Tight Adequacy Check
- 1Enter your values — Slip-critical? (1 yes / 0 no), Bolts in direct tension? (1/0), Fatigue/vibration/reversal? (1/0), A490/10.9 in certain cases? (1/0) (sensible defaults are pre-filled).
- 2Read the live results: Pretension triggers hit.
- 3Check the "with your numbers" line to see RCSC: pretension if slip-critical, direct tension, fatigue/reversal, or spec-listed cases substituted step by step.
- 4Adjust inputs until the scenario matches yours, then copy or share the result.
