too thin for 20 Series. T-Slot Profiles 6.7mm depth

While they may fit some T-Slot profiles advertised as 20 Series, there is more than one "standard" set of metric profiles with T-slots . sizes and these nuts are too small at 1mm for the spring balls to secure the nuts in my profiles

Pros
  • Certified
Cons
  • -

In general they are fine.

Most of them are fine but some of them were inaccurate. Either too flat and free-floating in profile, or the fin wasn't cut clean enough to not quite fit the profile, or it was too thick, or the ball spring was missing, etc. Still probably the best option on the Revain that I've found have.

Pros
  • Material: high-quality carbon steel, nickel-plated surface. These nuts have high hardness after assembly, long service life and good rust resistance. The rear spring ball can be locked, which makes assembly very easy and safe.
Cons
  • Nothing here

Does not work with LDO profiles

Will not fit LDO rails. I have other t-nuts that fit LDO rails and while LDO rails are firmer and are strongly discouraged as they won't accept m3 cage nuts, my other m5 cage nuts work but they won't so will I blame her this time. but actually they are LDO extrusions. So if you have Misumi extrusions, you might be fine.

Pros
  • Size: 7.9mm x 13.5mm x 4.4mm (W x D x H) Thread: M3 Metric.
Cons
  • Questionable purchase for the elderly

The first package 6 months ago arrived well. Two packs bought a week ago will not fit the same pads.

The first pack 6 months ago fitted well. 2 packs bought a week ago do not fit the same profiles. I don't recommend them as something has changed in the product and they don't fit my Misumi rails like the first pack (bought them from the same store a few months ago). seller - same part number). I tried 5 of each pack and each of them was able to shrink but didn't remove the extrusion when rotated to fix them - very disappointing!

Pros
  • 2020 Series Aluminum Profile T Nuts, widely used for industrial aluminum frame building, 3D printers, CNC routers, CNC laser cutters, robotic projects, 3D cutting machines, machine guards, workstations, etc.
Cons
  • I really don't like it, everything fits well

The "spline bead " is too wide for McMaster profiles.

Good product, good price. The nuts work well and the threads are not loose. However, I have found that the "bulge" that needs to go into the extrusion slot and align the nut is too wide for the McMaster Carr profiles I usually use. Annoying but not a serious problem unless fasteners are tightened to high torque which can damage the inside of the tread and/or warp the tread. I don't know if this is just a problem with McMaster Carr extrusion nuts or with these nuts, but I haven't had this…

Pros
  • Includes 20 pcs Spring Ball T-Nuts, they have clean threads and can be installed directly into the aluminum hole at any point of assembly, making your job easier.
Cons
  • Only available in white
