T-Nuts and Low-Profile Screws for 25 mm Rails




  • T-Nuts Fasten Rails to Other Mechanical Components
  • Low-Profile Channel Screws Provide Added Clearance

Features

  • T-Nuts Fasten Rails to Other Optomechanics
  • Four T-Nut Choices (See Image Above)
  • Low-Profile Channel Screws with Smaller Footprint than Standard Cap Screws

our T-Nuts and Low-Profile Channel Screws are designed to link 25 mm rails to other optomechanical components.

T-Nuts
T-Nuts effectively add 8-32 (M4) or 1/4"-20 (M6) tapped holes to the rail sides, permitting a wide range of standard optomechanics to be fastened to the rails. Our T-Nuts are available in three styles—Quick-Release, Drop-In, and Low-Profile—which are detailed in the text below.

 


Quick-Release T-Nuts for 25 mm Rails

 

  • Can Be Inserted and Removed from Any Exposed Portion of a Rail Channel Without Accessing the Ends as Shown in the Animation to the Right
  • Drops into Position and Locks by Rotating
  • More Surface Engagement than Drop-In and Low-Profile T-Nuts
  • 8-32 (M4) Tapped Hole for Mounting

The XE25T4(/M) Quick-Release T-Nut is our most versatile option for mounting mechanics to 25 mm rails. Its thin width profile allows it to be inserted into an exposed rail channel. After being inserted, a clockwise rotation by 90° prevents it from being removed again. Once rotated, screwing in a mechanical part draws the T-Nut away from the rail's center axis, eventually forcing the T-Nut and rail channel to engage. The protruding edge of the 8-32 (M4) tapped hole centers the T-Nut within the rail channel, ensuring even engagement on both sides.

To remove the Quick-Release T-Nut, simply remove any attached mechanical parts and rotate the T-Nut counterclockwise.

 

Drop-In T-Nuts for 25 mm Rails

 

  • Can Be Dropped into Any Exposed Portion of a Rail Channel Without Accessing the Ends
  • Removal Requires Access to the Rail Ends
  • 8-32 (M4) Tapped Hole or 1/4"-20 (M6) Tapped Hole for Mounting

Drop-In T-Nuts can be dropped in along any point of an exposed rail channel, making them easy to install even if the rail ends are blocked. They are available with either an 8-32 (M4) tapped hole [Item # XE25T2(/M)] or 1/4"-20 (M6) tapped hole [Item # XE25T1(/M)].

Although these T-Nuts can be easily inserted anywhere along the rail, access to the end of the rail is necessary for removal. This procedure is shown in the animation to the right. In contrast, our Quick-Release T-Nuts, shown above, offer the added flexibility of being able to be removed when the rail ends are obstructed.

 

Low-Profile T-Nuts for 25 mm Rails

 

  • an Only Be Inserted and Removed from the End of a Rail
  • 1/4"-20 (M6) Tapped Hole for Mounting
  • Economical Alternative to Drop-In and Quick-Release T-Nuts

The XE25T3(/M) Low-Profile T-Nut can be used when there is access to the rail end, which allows the T-Nut to slip into place. Since installation (and removal) requires the rail end to be unobstructed, as shown in the animation to the right, this T-Nut usually needs to be positioned before an XE25-based mechanical construction is completed.

Our Quick-Release and Drop-In T-Nuts, shown above, can be inserted and removed even if the rail ends are blocked.

 

Low-Profile Channel Screws

 

  • Sold in Boxes of 100 Screws
  • SH25LP38: 1/4"-20 Threading, 1/8" Hex Head
  • SH6M10LP: M6 Threading, 4 mm Hex Head

Our Low-Profile Channel Screws have a reduced cap height relative to standard screws, permitting them to be used in tight spaces. In particular, they are recommended when neighboring screws are at a right angle and in close proximity, as in our XE25W3 Corner Cube or RM1G Construction Cube.

Shown to the right are a standard cap screw and a low-profile channel screw installed in an RM1G cube. The low-profile screw's shortened cap height prevents neighboring screws from interfering with each other.
