About this asset

This A325 heavy hex nut is a native Revit family component featuring accurate thread geometry for high-strength structural assemblies. The A325 heavy hex nut is designed as a precise 3D component for structural steel detailing. It features a standard heavy-duty hexagonal profile with clean, defined edges and a central aperture with modelled internal threading. The geometry is clean and lightweight, ensuring it does not bloat project files while remaining visually recognisable in 3D views and sections. The finish is a neutral grey, representative of standard galvanised or plain steel fasteners. This component is essential for engineers and detailers who require accurate representation of bolted connections within their BIM workflows.

The download is a 440 KB file containing a Revit family (.rfa). Load it into a project from the Insert tab with Load Family, then place it like any other component of its category; it schedules and tags with the rest of your model.

In Revit, this fastener family can be loaded into a project or nested within a structural connection family. It is typically hosted on reference planes or bolt points to ensure accurate placement. Users should manage visibility settings to ensure the threaded detail does not cause graphical lag in large-scale structural models. It is recommended to use this in conjunction with bolt and washer families to create complete, schedule-ready connection assemblies for structural steel projects.

This fastener is intended for use in structural engineering and steel construction projects where precise connection modelling is required. It is suitable for detailing steel frames, trusses, and industrial platforms. Architects and structural engineers will find this useful for BIM coordination, particularly when resolving clashes in complex steel nodes. It pairs well with standard A325 bolt families and structural steel sections, making it a reliable asset for creating detailed shop drawings or high-fidelity construction documentation in professional architectural and engineering workflows.
