great little clamps well made

Bought the 3018 Pro milling machine as an introductory tool to milling "bigger" things. The DIY project went together very nicely and ran the samples supplied with ease. What I didn't really care for the the clamping system supplied for the "Y" axis for many reasons I'll not go into here. I found these hold-down clamps advertised in their brochure and decided to try them. I use a lot of purchased and home made clamps for "T" gigs for metal and woodworking and have some much larger that wouldn't work with this smaller surface. The clamps arrived on time and in a very well protected holder for storage. They are very well made and worth the money, buttttt- now for a minor problem to dampen the glory. They have a spring that holds the center of the clamp up while adjusting and tightening the clamp, this was an annoyance as the spring would flex under the clamp and get into the threads of the clamp bolt preventing it to be tightened down any further until it was pulled out of the threads. The spring is tapered with the large end sitting against a nylon washer under the clamp arm. To eliminate the problem I machined shoulder washers for the two clamps that keep the spring centered on the screw and moved the nylon washer to the top just under the star nut. Works great and I'm sure you can find shoulder washers online if you want to do the same. Was just a little more fun and experience making my own!. FYI, the screws are M6x1 thread.

These are great, they made clamping the material much faster and easier. Compared to the clamps that came with my 3018 pro it's night and day. They hold very well and the quality is great.

As others have mentioned the T-track nut on these didn't fit what I consider a normal T-track. My Powertec T-tracks were slightly narrower and have a 90 shelf if you will on the bottom where the T branches out. These T nuts instead of a lower 90 shelf are beveled or chamfered down like they were designed to work with aluminum extrusion but they are to large to fit in 2020 and to small to work with 4040. Maybe they're designed for 3030 but I don't have any. The price was right and I knew they might not fit when I ordered them and didn't balk at reshaping them on the grinder till they fit nice.

These clamps were made for the machine, not just some sort of generic product. The packaging was above and beyond. They work very smoothly. It's pretty expensive for a tiny set of clamps but at the end of the day you won't be disappointed. Aligning a 3018 is already enough of a pain. The last thing you want to be doing is fiddling around with clamps that require a screwdriver or worrying about taping stuff down.

Purchased for use on a Micro-Mark mini-mill. I suspected the T-nuts would be too small for my application, and planned to make new ones. I've attached some pictures clearly showing the dimensions so you can decide if these will work for you without modification. The threaded rod is M6-1.00. The T-nut is designed for an 8mm groove. The base of the T-nut is just under 16mm square and 6mm thick. For my intended use, it was a simple matter to make new T-nuts. I'm very pleased with these clamps.

kind of annoyed these dont come standard with all CNCs instead of those obnoxious bolts + washers + butterfly nuts. they clamp down quickly and easily and hold everything down firm. I bought 2 sets so i have 4 clamps total for my 3018. right now, i will never not use this type of clamp.

Should have read closer, these will not fit standard T-track

Ottima qualità. Indispensabili....mi hanno cambiato la vita rispetto ai blocchi originali. Sicuramente da avere.

Die sehr teuren Klemmen sind mit Nutensteinen ausgestattet, die nicht überall passen. Vielleicht auf so Tischschienen, aber nicht in eine T-Nutenplatte von CNC-Maschinen wie z.B. Isel. Aber es gibt ja andere Steine zu kaufen. Gemacht, getan... Steile mit gefederter Kugel gekauft, die Gewindestange umgesetzt und mit einer Made gegen Verdrehen gesichert. So kann man am Knauf drehen, ohne daß sich die Gewindestange rausdreht oder sich in der Platte verklemmt. Die Klemmen sind schön flach, man kann auch erhöhte Platten klemmen, bei denen man durchfräsen muß. Halten sehr gut und werden sicher lange ihren Zweck erfüllen. Leider nur in silbrig / Alu-Natur erhältlich, nicht in rot. Dennoch sehr teuer für so China-Ware.

These clamps hold incredibly well. I use them with FoxAlien Masuter Pro; just remove the t-slot nuts. They are low profile and provide either a short or medium reach. The pivot on them helps to keep them secure and well-aligned, and they are easy to tighten and remove.

Très bon produit, de très bonne qualité, merci ... André du sud est France.

バネ+ポリアセワッシャーはいらないですね。ちょっとしたことでイラッとしますので、とっぱらいました。その後快適です。
