A bolted joint has one job: clamp the parts — without separating, slipping or overstressing anything in service.
This tool evaluates preload, load sharing, temperature effects and the critical safety checks in seconds, and presents the outcome as a clear PASS/FAIL table.

This tool is built on the internationally accepted analysis systematics for preloaded bolted joints (VDI 2230 approach; NASA-STD-5020 criteria framework), configured for a common case: a circular bolt pattern, an axial separating load and/or a torque-induced transverse (slip) load, a single fastener type and clamped members acting in series. The calculation core has been verified against a high-temperature reference case and an automated suite of ~4,000 scenarios. Real situations departing from these assumptions (eccentric/prying loads, gasketed sealing joints, multi-axis load combinations, fatigue assessment, etc.) require joint-specific treatment; material values are representative. Acceptance targets (margin thresholds) are configurable defaults based on common engineering practice. The tool is intended for capability demonstration and preliminary assessment; it may contain errors, omissions and, in some cases, software defects, and must not be relied upon alone for design or acceptance decisions.
