Hammer nuts and slide-in T-nuts both create threaded attachment points in aluminum extrusion, but they suit different assembly methods. Selecting the right one helps reduce rework, protects the profile slot, and gives the assembly team a more predictable installation process.
How hammer nuts work
A hammer nut is inserted into a T-slot and rotated into position. Its geometry is designed to engage the slot after turning, so it is useful when access to the profile end is limited. For a project, confirm the slot series, thread size, material, surface finish, and required clamp load before ordering. QIYI hammer nuts are offered in carbon steel or stainless steel with zinc or nickel plating, with thread options stated from M3 to M8.
How slide-in T-nuts work
A slide-in T-nut enters from the open end of the aluminum profile and moves along the slot to the required location. This makes it a practical choice when many fasteners must be positioned before the frame is closed. It can also make alignment easier on longer assemblies where repeated spacing is required.
Selection checklist
- Match the nut to the profile slot width and series.
- Choose the thread to match the bolt or accessory.
- Check whether the nut must be installed after the frame is assembled.
- Select corrosion protection appropriate to the working environment.
- Confirm the load path and tightening requirement with the assembly drawing.
Which option should you use?
Choose a hammer nut when you need to add a fixing point from the side after the profile frame has been assembled. Choose a slide-in T-nut when you can load components from the end of the extrusion and want to position several fixing points efficiently. For custom projects, provide the profile section drawing, slot dimensions, thread size, quantity, and application environment when requesting a quotation.
