Genmitsu2PCS T-Track Hold Down Clamp Kit, for Woodworking Metalworking, Compatible with MDF Spoilboard with 6mm(0.24'') Threaded Hole and Aluminum Spoilboard for M6 T-slot Nut 16 x 16mm(0.6 x 0.6'')

All the optional parts I purchased are the same quality as the Frame and CNC machine.

This clamp looks great on page but useless, save your money look else ware poor quality clamp. way over priced!

I was excited to see these finally listed for the proverXL. I received a box labelled with the same item number that is listed on the Sainsmart website. Both amazon and Sainsmart list this as the new clamps for the prover 4030XL. The T-nuts are completely the wrong size for the proverXL, with the official aluminum bed. They also do not match what is shown in the image on the site. They will not fit into the slots. It's like I want to give SainSmart a good review but they just keep sabotaging themselves over and over. Nice clamps other than they do not work with the prover 4030XL...

These are thick aluminum. The milling and finish work is excellent. The screws and handles appear not to be cheap. They hold well. Great item.

I enjoy woodworking and use of a router with table. A solid set of hold down clamps is necessary for best work results. These are very well done with 2 positions to allow different thicknesses to be clamped. The plastic knobs have brass threaded inserts as they must. Be sure that the T Track can take a 16mm wide T Slot nut which is what these use; the shaft and nut are M6 Threaded. See the listing for exact dimensions.I Recommend these Genmitsu Brand 2PCS T-Track Hold Down Clamp Kit, for Woodworking Metalworking, Compatible with MDF Spoilboard with 6mm(0.24'') Threaded Hole and Aluminum Spoilboard for M6 T-slot Nut 16 x 16mm(0.6 x 0.6''). A bit pricey but well made for my purposes.I hope you’ve found the information and my review helpful.

i used these on my ww track table built by Kregg,changed out the hardware so it fits....well built clamps, price is on par with Rocklerfast way to get something clamped donw on a tablethe only thing faster is the Bessey QR hold down clamps...

I obtained this to use with my Shapeoko 4 XL CNC router. It fit the channels perfectly. I like the length of the arms as it will give me more room to work with given the spaces between the tracks are fixed. Also because they are long they can accommodate material up to 50mm (1.97'') thick. I also like that it has a spring under the tightener. I don't have that feature in any of the other clamps I own. The high strength 6061 aluminum alloy will be useful when cutting something hard as it can take the pressure from the router.

卓上用には少し大きいですが、工夫次第です。気に入ってます。

Perfekt gerne wieder

Excellent quality, well manufactured.

Aber schlecht verkauft.........Heute ist also das Paketerl bei mir angekommen und der erste Eindruck ist sehr gut. Die zwei Klammern waren hochwertig in Schaumstoff verpackt und auch die Verarbeitung wirkte auf mich sehr gut.Leider........ ja leider ist der mitgelieferte Nutenstein (8 mm Bosch Rexroth) zu groß für meine 30x40er Fräse. Gut ich habe mir dann etwas aus einem Flachstahl selber gebastelt, aber da hätte man von der Verkäuferseite etwas mitdenken können.Wer sich also überlegt, sich so ein Set zu kaufen, sollte zuerst die Nutenbreite der Aufspannplatte abmessen.Die Nutenbreite meines Aufspanntisches von 6 mm ist einfach zu klein, benötigt werden 8 mm Nutenbreite, das gilt auch für die kleinen Klammern.Vielleicht ist der Verkäufer so schlau und gibt bei den nächsten Klammern noch alternative Nutensteine dazu. 2 Stk. M 6 Muttern würden schon reichen um die Klammern auch auf den kleinen Fräsen (30x40-30x20) einsetzbar zu machen.

Tolle Idee..
