What you will learn - SNUG: Connected plies in firm contact. - PRE: Specified minimum bolt pretension. - SLIP: Slip resistance at faying surfaces. - VERIFY: Installation and inspection requirements.

Design documents, project specifications, and the governing RCSC requirements control. Tension-control assemblies can be used in different joint conditions. A severed spline alone does not establish that a joint was properly pretensioned.

[Open related reference](https://www.quantumsteeldesign.com/learning-hub/steel-connections/#bolts-welds) Companion reading and practice ## Which requirement is being specified? A training connection note names a joint requirement, while a material list names the bolt assembly. Those pieces of information answer different questions. Read the specified joint category together with the assembly, holes, surfaces, installation, and inspection requirements. The terms in the video are not interchangeable labels for bolt strength. The applicable RCSC specification and project documents establish the requirements for the actual joint. ### Try it with a sample Make a small reference list for one training connection and mark any missing requirement as an open item.

Accessible transcript ## Snug-tightened, pretensioned, and slip-critical joints transcript The visible transcript makes the video content available to people and search systems without requiring playback. - The same bolt diameter can serve different structural joint requirements. - High-strength bolted joints may be snug-tightened, pretensioned, or slip-critical. - Snug-tight brings plies into firm contact, with no specified minimum installed tension. - Pretensioned joints require specified minimum bolt pretension and an approved installation method. - Slip-critical joints use pretensioned bolts plus specified faying-surface slip resistance, so surface condition and hole type matter. - A tension-control bolt can serve different conditions; a severed spline alone does not prove pretension. - Design documents and project specifications—not AI or shop habit—identify the required condition. - AI can flag conflicts; qualified teams must resolve, install, and inspect under the governing RCSC specification.
