Zipbolt Slipfix Rail Bolt 13.810, Metallic, 1 Double Pack with Wood Plugs

The idea seems sound enough, but the product was not up to the job. It all seemed very straight forward, however, when it came to tightening the screw thread up to ensure a snugg tight fit, it didn't. Therefore, having waited for the product to do the best job I thought I could, I'm afraid it was back to good old screws.Disappointing.

Strong connection. Highly recommend

Great product, made installing my railing a breeze.

Easy but don’t necessarily follow the individual, make a test first. For me, it needed different mesures. The look is flawless and it is sturdy and solid

…but you must actually read and follow the directions or watch the video. I wish you could order the gear head separately.

If you follow the measurements precisely, they work like a charm!
