Extension Screws for Binding Screws - Silver / Nickel - 5mm
5mm extension screws are compatible with all Gobrecht & Ulrich binding screws from 10 mm length. These extension screws can increase the capacity of your screw post binding without buying longer binding screws than the ones you might already have. You'll only receive extension screws without matching screw posts.
The extension screw has two parts. First, a binding post extension of 5mm length, with a standard 5mm hole diameter. Second, a 7.5mm screw thread, which can be used with any matching screw post from 10mm length. The screw head is slotted.
Easily increase the maximum capacity of your screw post binding
Simply use this extension screw instead of your standard screw and extend the length of your binding screw by 5mm.
