Countertop Joint Fasteners Double Action - 4-Pack, Flip Bolt Fastener for Counter-top Table-top Connector Hardware, Miter Draw Bolt Joint Seam Woodwork Surface Connector Kit

I read plenty of reviews and had my reservations, but decided these couldn't hurt to try. I was debating on using biscuits and pocket screws or traditional clamping bolts on my butcher block install, as I was assembling them I tried these to see if they would do the job.Installation is relatively simple. I did have to add these to the underside after setting counters and it wasn't too bad. The clamping action was very sufficient at tightening up my gaps, and the adjustment features allowed for smooth, flush counter surfaces at the seams with no additional finishing. I added pocket screws to keep things right after using these to set level and close the gap.The screws included were sufficient, but as others have stated, if you have adequate material thickness, consider a slightly longer screw. I didn't rip any screws out, but I could see the screws being an issue if the joints were overtightened.The only downside I found was locating at joints with cabinetry adjacent. The hardware was interfering on one joint which would have required me to route a section of cabinetry to fit the hardware. Clamp bolts would have worked in that location.

Used these to connect 2 butcher block countertops in our new kitchen. Finished look is great, worked exactly as needed. The only thing I would do different is install them to the last top before placing. Would make installing final screws easier inside a cabinet.

I’d never seen or tried this type of miter hardware before. NO ROUTING REQ. The adjustments up, down, sideways and along the cut WORKS AMAZINGLY well! I will use only these from now on. Only two minor issues: 1. No included installation instructions. (had to figure it out on my own.) 2. The sub-top underneath, had to be cut open to allow for the bulk of the hardware to pass through & the countertop to sit down flat. (careful with the lazy susan location ‘cause you don’t want to cut out where it attaches up top) This wasn't that big of a deal. I’m pretty happy with this product.

Made installing a three piece counter top way easier.

We used these to connect and level a counter top we put in our small cabin. They look complicated but did the job perfectly! This was our first time doing anything like this and I’m very pleased with how it turned out.

I dont know what the bad review leavers are experiencing. These worked flawlessly for meI did get different screws, only because I don't like the square head. Rather use Phillips head. But these installed with no problem. Screws didn't strip and it pulled the two pieces of WHiTE OAK butcher block together easily

We're putting in butcher block countertops with an island, I had bought a biscuit cutter with biscuits too secure the two countertops as they turned direction. After seeing these I thought it may be better and it worked like a charm. It brought the two pieces together and leveled them at the same time. Very pleased!

This is a good idea and worked great, half the time. The other half the bolt stripped out while tightening. Since the head of the bolt is round and snug against the counter top it wont tighten or loosen. My only option would be to remove it, put in another hoping to not strip out the screw holes in the wood, and then hope it didn't happen again.
