Great value, solid construction
Reviewed in the United States on December 31, 2020

I just got this set yesterday, looked it over, but haven't used it.
This set fits the 5/8" slots on my Grizzly G1007 round column RongFu clone mill beautifully.
The finish is slightly rough, but only visually. All the threads operate smoothly, and the working faces are all uniform.
The T-slot anchors are not tapped all the way through, which is correct.
The studs do not have milled flats. I don't mind that- they're not bolts that should be heavily torqued.
The step blocks are US manufactured from powdered metal, and seem clean and uniform. They have a slightly sharp burr on the sides, where the molds parted. This is not on the operating faces, but I'll probably hit it on a sander for the sake of my fingers. They are as dimensionally accurate as my cheap digital calipers- 0.000" difference from one set to the next.
The plastic holder is made in Taiwan. It looks as though it will serve well as a bench organizer, but I won't be hanging it on the wall.
The bolts have zero rust, and are clean and well oiled. The step blocks could use some oil, but still no rust.
This is a great middle ground between China junk and first-quality pricing. Not so pretty, but smoothly functional.

Much nicer fit and finish than a similarly priced import set
Reviewed in the United States on March 27, 2024
Verified Purchase
I had purchased an supposedly "high quality" import set for my Bridgeport, but it was garbage. This TE-CO set is made in the USA and the quality is significantly better. This set has sintered step blocks instead of ones cut and machined from bar stock. The machining on the straps is clean, and the threads of the screws, nuts, and T-nuts are also clean. No burrs to be found on any parts. Aesthetically they could perhaps look a little better - the Parkerizing appears a bit uneven, but that's a minor quibble for USA-made at this price point.

The plastic organizer is imported - you can pay more and get a set from TE-CO with a USA-made metal holder but I honestly prefer these plastic ones.

Decent Set
Reviewed in the United States on January 14, 2019
Verified Purchase
MUCH better quality than the Chinese imports for $25 or so more! The T-nuts fit the 5/8th slot in my milling machine table very well, with acceptable tolerance. The studs will bottom out in the T-nuts, but this should not be an issue when using the hold down set properly. The holder is plastic and would probably break if not supported from underneath. I am simply going to make an L-shaped cradle out of 3/4" plywood for the plastic holder- problem solved. Considering that the next step up from this set is double the price, some minor things like a plastic holder and the absence of a thread cleaner are not going to keep me from giving it 5 stars.

USA made, Plastic Holder, but as the TITLE SAYS, "PROMO"
Reviewed in the United States on July 10, 2021
Verified Purchase
Step Blocks are true 90 degrees square.
Import Brands are not square ground. They are ground at a slight degree from being a true 90 degrees. Which causes the hold down brackets to have more pressure on one corner leaving marks on your products.
Best buy on the market for USA. Messed around with the Chin'e brands, and the chine t-nuts allow the studs to be screwed into your table, Te-co's are bottom tapped, and stops so your hold down bolts, won't mess up your table. Another interesting point is the slots in the hold down bars, on chinese whether 7/16-1/2 inch, the slots are milled out to large. Te-co are milled to tolerance, for even distribution positioning.
The plastic holder is marked USA made. It is thick plastic, but as"the title says"
"PROMO Kit". Which means Promotional/introductory into a USA made set for a lesser price.
If you want the steel holder, pay the extra money for the Higher Priced Te-co sets. I have mine placed on a shelf, so it doesn't bother me.
I have ordered two sets of chinese knockoffs, and ended up returning them because of poor quality. Spend and extra $25.00, and got a really nice set. Very happy now.

Teco is superior to import sets.
Reviewed in the United States on February 7, 2021
Verified Purchase
Do youself a favor and buy this set, do NOT try to save 20 bucks and buy an import set. The import sets suck so freaking bad. I know, I have an import set and I've seen others import sets. This teco set is made in USA, except for the rack, the rack gets bad reviews but I don't know why, it's really good plastic and it's made well. The difference between this set and the 200 dollar teco set is not the blocks as so many ignorant people often say, the blocks are the same, the difference is the studs. 1541 vs 4340 chromolly and flats machined on the 4340 also. Other than that and the metal rack it's all the same. Same straps, same blocks, same tnuts, same nuts, different studs and rack. Your not gonna break these studs though, you'll screw up your table torquing before you bust these 1541 studs. That the same material in the rear axle shafts on my Jeep by the way. This set is superior to any import set and the price is only like 20 to 30 bucks more. You will have pride using these and be glad you bought them. If you go import to save a buck you'll hide them and be ashamed of them. The import ones look nasty, and not a good nasty like Mrs. Jackson either. I have an import set I bought to use with my mini mill about 15 years ago and they are gross. When I bought a bigger set for my Bridgeport I bought this Teco set and I am so happy I did, these things are nice. Very well made and a joy to use. Some import stuff is ok, but not a clamp set, they suck.
