Woodworking Experience:
Great looking and functional clamps
I use them in cases where I don't need a lot of adjustments and move the jig a lot. Using the lever is much quicker than having to turn a knob.
They cost more so I would not use them everywhere. They also take up more space.

Very well made
Yes, the accessory bolts are glorified toilet flange bolts, but I needed a long length and these worked well. Fit and finish impeccable, just what I needed for my project.

Clamps work great. Bought a couple of sets had an issue with one clamp, Rockler immediately took care of the issue, very happy with the product and the customer service.

Works Great
They are easy to use and hold down this fence super tight. Converted some bench dog fences into T-Track fences with these clam clamps. They really hold tight and work great.
Converted this bench dog fence with Cam Clamps for the Rockler T-Track system. After Picture

love them
I wish I had bought these much sooner. It makes clamping much baster and easier compared to the knobs I had been using.

My Kreg router table has 2 t-knobs too close to each other. I will replace one pair with the cam levers so there will be more room.

I plan to use these clamps to attach an auxiliary fence to my Festool Kapek miter saw. They will replace wing nuts to make removing and replacing the fence easier and faster.

These were recommended to use on a music stand that my husband is making. Since it was a Rockler product, I knew there was no question of quality.
DEBORAH S on Nov 8, 2017
Needed them to fix a issue with a small CNC machine that has issues with object slipping. It is already slotted so it just makes sense.

while im not crazy about the blue color, i am crazy about 5/16th hardware in a compact package. All the others i've seen are substantially larger than the 1/4" counterparts. I was pleased to find a more compact 5/16th cam lever, AND IT IS BLUE TO BOOT!!! i CAN'T WAIT TO GET MY HANDS ON THESE BABIES....sorry bout the outburst, i'll go home and try to wait patiently. thank-you.

What is the 'throw' of the 5/16 clamp (how far does it pull the bolt in)?
Ned T on Sep 14, 2015
BEST ANSWER: about 3/16"
Are these clamps ferrous/magnetic? Intended for use with an MRI compatible robotic support.
Mitch S on Nov 10, 2017
BEST ANSWER: The blue clamps are not magnetic. the bolts are steel and magnetic.
Is there a clamp force specification for these? I'm hoping to use these as part of the design project for my mech. eng. degree (it would be a LOT easier, and better quality, than having work out a design for this myself) and I would need to have that sort of data.
Chris B on Apr 15, 2020
I actually haven't had a chance to use these clamps, but I'm pretty positive they are aluminum and made for woodworkers. There are no clamping pressure specifications for these clamps. Woodworkers generally aren't interest in how much pressure is exerted on a piece of wood, just that there is enough pressure without breaking the clamp. The pressure force from this clamp is adjustable and thus variable, and the larger the screw/barrel bolt, the greater the force available. You could derive some ballpark torque figures yourself by using a pocket hook scale, such as is used to weigh suitcases or for fishing.
If Rockler would provide you with a contact for the manufacturer of these clamps, you might find your answer.
Sorry I couldn't be more help.
Where are the accessory long hold down supports shown in the video that accompanies this product at the 43 second mark?
Keith D on Jul 10, 2019
BEST ANSWER: Based on the video, it looks like what you want the Rockler Hold Down Clamp, 5-1/2''L x 1-1/8''W. It looks like they replaced the standard star knob that comes with the clamp and replaced it with the cam lever. Looks like you would have to purchase both items to duplicate the setup shown.
What are the dimensions of the handle?
Jonathan S on Dec 8, 2015
BEST ANSWER: Approx. 3.25" x .75" for the 5/16" version. I believe the 1/4" version is the same. I have both versions; the only difference appears to be in the insert for the hold-down bolt. I am using them to clamp down the fences on my shop-built router table and auxiliary drill press table. Much more convenient than the threaded knobs I was using before I got these.
Do they come in another color? Red?
Ricebiker on Nov 6, 2015
BEST ANSWER: Have never seen them in a color other than blue, including at the Rockler store near me.
What are the dimensions of the heads of the T-track bolts?
A shopper on Aug 21, 2015
BEST ANSWER: The 1/4" cam works with a standard 1/4" hex head bolt I bought at Ace Hardware or Home Depot. The 5/16" cam works with a 5/16" toilet bolt. Don't have the actual dimensions of the bolt head, but believe they are standardized and readily available. I bought the Rockler T- track to use with the cam lock. They secure a lamp and gooseneck to hold my tablet at my lathe station and the fence on my router table. They work much better and faster than the knobs I was using before. Great product and will order more for similar applications.
