How Fasteners Work with T-Slotted Aluminum Framing

A major advantage of using modular aluminum framing over welded steel is that the t-slot that allows infinite mounting locations for accessories. Common examples of these are in-fill panels, interlock switches, pneumatic or electronic components, mechanical components, etc. Depending on the profile series chosen you can select a wide variety of thread sizes to best fit the component you are trying to mount. The hardware is typically categorized by a t-slot width designator within the product ID that will allow a fast understanding of commonality with a particular profile size.

Ex: TN10M6 - a t-nut for the 10mm wide t-slot that is found on 40mm profiles and up and will show a symbol. Also, this t-nut has an M6 thread and will work on any profile showing the corresponding t-slot symbol allowing fast reference.

Once the t-slot width is identified it’s a simple choice for thread size based on the component being mounted & the style of fastener desired. The most common fastener type is the t-nut. This is a post-assembly or drop-in style that can be inserted anywhere the t-slot is available. This series nut has an elliptical shoulder which, with a 90° turn, aligns within the upper portion of the t-slot & locks into the t-slot with a strong, vibration proof & electrically conductive connection.

Roll-in or Drop-in t-slot nuts function in a similar fashion with the additional benefit of having either a leaf-spring, ball-spring or set-screw for retaining their position in the t-slot. This is very beneficial when used for mounting table-tops or surface mounted plates as you don’t want these fasteners to move when the top is un-bolted. These also hold their position when used in a vertical t-slot & won’t slide down or fall out.

T-Bolts are commonly used & function just as the t-nuts do in that they have a similar shaped head with the locking feature & a male thread available in various lengths. Use the –“W” suffix & a flange nut will be included to assist in the mounting of your clad-on panel or other equipment. As you can see below, here are all the aluminum fastener types we carry.

Fastener Types We Carry
