binifiMux 10-Set M6x20mm Rivet Countersunk Hex Socket Cap Bolts and Hex Head Barrel Nuts for Furnitures Cribs Chairs, Nickel Plated

Great product

I initially ordered the 35mm to connect 5 Ikea Billy Bookcases but 35mm just did not hold them together close enough for my liking. Re-ordered the 30mm and now the bookcases are nice and snug with no gaps.

I bought these 35mm sized connectors at the recommendation of a U Tube video to attach Ikea's billy shelves as well as some of the listed reviews. They turned out to be a few mm too long to make a tight connection between the shelves I should had to measured the distance myself. If you need to attach Billy shelves us 30 mm length they will make a tight connection. I have no complaints about the quality of the connectors, I will use them for jobs.

Nice set of connecting bolts, they are hard-to-find elsewhere! Beware though, these are a bit longer than expected. I needed to bolt boards together that had a total thickness of 1.5" (38.1 mm). I first bought the 40mm bolts, thinking the nut would screw on far enough to hold the boards securely, but the nut only screws on 3/4 of the way down its shaft, so despite the screw part of the bolt extending 40mm from its head (as expected), the 40mm bolts are more appropriate for a gap of about 42-47 mm. The 35mm bolts are the perfect length for what I need though, they seem to work for a gap range of about 37-42 mm. It would be nice for binifiMux to provide a chart mentioning what bolt length you need for a specific gap length.

Found these screws off an IKEA hack from YouTube. 35mm is the best size to attach the Ikea Billy Bookcases together.

These are perfect for what I need them for.

Excellent product. Easy to use, looks good. We used it to connect several Billy bookcases from Ikea

I thought I would receive five screws and five connecting caps, but I received five screws and two connecting caps.Otherwise the product is as described.

Although we did not end up needing the hardware because they were not the perfect fit, customer service was excellent. Delivery was quick and refund was issued just as quickly. Communication was great.
