  • Very high quality. Work very well in a 3/4" bench hole.
Style: Holdfast
Using these with thick, nearly 3 " thick bench and 3/4" diameter dog holes. They work perfectly one hit and bang their set one hit and they're loose. This bench is very old over 50 years and doesn't have a lot of dog holes. I'm changing that. Using hold fasts and dogs. No wood vise here!! These are heavy and great quality. ... show more

  • A Workbench Necessity
Style: Holdfast
One of the most valuable and essential woodworker's tools to own. Simple in design and operation, they make your projects and your life infinitely less difficult. These in particular are built solid, work great, and will most likely last a lifetime. I (and a few other people) did have to make minor modifications to the contact surfaces because they were too rough for use on the finished timber I work with, however, they were insignificant. A quick swipe or two with a flap disk on my angle grinder and a little primer/paint and problem solved. You could easily create the same results with a file if needed. I have zero regrets about this purchase. ... show more

  • Good. Could be better. Some critiques ...
Style: Holdfast
I was looking for a smaller set of holdfasts for when I need a bit less reach, and these holdfasts seem to fit the bill. My dogholes on my benches are 3/4" x 3" deep. Immediately after receiving these, I went directly to my bench. I did a side by side comparison of these to my Gramercy holdfasts. All told, I'm happy with the purchase for what was paid. They have the same shaft size. There was another review that mentioned that the shaft is smaller than the typical 13/16 measurement, which would wear the dogholes faster. This is not my case. These holdfasts have a rough powder coat, and even ribbed where they are molded. I would have thought maybe they'd grip better than my Gramercys, which are smooth, but that doesn't seem the case. They are almost as good, tending to loosen a bit quicker than the Gramercys. The shape of the part that contacts your work is not flat. This could result in more damage to your work, and even create a potential pivot point for your work to move on. I'm thinking about filing mine flat for a better contact surface. ... show more

  • Grips firmly.
Style: Bench dog stops
I use these for wood working. I just set them down on the bench and place my work piece on top to sand or paint. They grip the table and workpiece very well, nothing moves.

  • Very useful
Style: Bench dog stops
These work very well as a base with a palm router as well as stands for staining.

  • Started slipping
Style: Holdfast
Started out pretty solid, but saw a bit of a bin in it after a little while and in about 3 to 4 months after purchasing them and using them a good bit, they just kind of stopped holding. Probably could be longer or have a different finish.

  • Best investment for a wood working bench
Style: Holdfast
These do what they are meant to do which is Hold your piece and Fast. Loosening is just as fast. I used these recently to lock down pieces that needed nails removed and then cut with a jigsaw. They did not vibrate lose which can happen with Quick release squeeze clamps. Sturdy,value, quality

  • Didn't work for me at all, had to find something else.
Style: Holdfast
I bought these hold-fasts because I made an old-timey English joiner's bench. They did not hold in the 3/4" holes I bored in the bench. I tried smacking them with every hammer I had, in every place on the holdfast, and they just don't hold. Doing more research, I learned that cast holdfasts like these have issues with that, plus they have a reputation of breaking on the neck because they just don't flex properly. Live and learn. I ended up making a charcoal forge and forming my own from 5/8" mild steel rod I purchased at a box store. The ones I made hold in every hole on the bench, which is a relief because I thought I had ruined it by deforming the holes with the cast ones. Very glad I didn't have to replace the bench I had worked so hard on. Don't buy these... ... show more
