Best clamps use so far from Sainsmart

These are awesome little hold downs, they are great quality and I would definitely recommend them to anyone..

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...

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

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.

I GOT THESES T RAIL CLAMPS FOR MY T RAILS ON MY BOAT, I MODIFIED THEM SLIGHTLY WELL ALL I DID WAS DRILL A HOLE IN THEM TO BOLT ON A 12VT LED LIGHT TO THEM FOR NIGHT FISHING AND BOW FISHING MAKES IT EASIER TO MOVE THE LIGHTS WHERE I NEED THEM TO SHINE, THEY WORK GREATI WILL UPDATE THIS REVIEW WITH PICTURES IN A FEW WEEKSTO SHOW YOU HOW THEY WORK WITH MY SET UP ON THE BOAT I AM REBUILDING MY BOAT MAKING IT MORE FISHABLE PUTTING IN A NEW FRONT DECK ECTBUT THESE T RAIL CLAMPS HOLD TIGHTLY INPLACE AND DO NOT MOVE ABOUT EVEN WHILE BOUCING ACROSS THE LAKE AT 25MPH GREAT VALUE FOR THE MONEY AND ARE EASY TO USE JUST SLIDE THEM IN THE RAILS AND CLAMP YOUR WOOD METAL OR WHAT EVERY YOU ARE WORKING ON DOWNI HIGHLY RECOMMEND THEM

This is great looking product with spring loaded post, and two positions to set the angle of clamping. However, it doesn't fit any of my T-Track. I'll try and replace the post with a 1/4" T-bolt and reuse the spring.

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.
