zinc-plated steel • extendable
This is a 6-pack of brass 20mm extension posts 32EP20-6 which can be used to lengthen any post-&-screws from our range of brass, silver or black interscrews.
Extensions are made from zinc-plated steel, and are not coloured to match the interscrews. This is usually inconsequential, since the posts are typically concealed by the item being bound.
Post length 20mm. Post diameter 5mm.
Extensions are available in 7mm, 10mm, 15mm, 20mm, 30mm, 40mm, 50mm and 60mm lengths.
We also carry a range of brass, silver and black interscrews in various lengths. Interscrews, also known as post-&-screw sets, are the 'top and bottom' pieces for the extensions.
WHAT'S WHAT IN INTERSCREWS:
Variables such as length, depth, diameter, thread length and pitch mean that it is HIGHLY UNLIKELY that our interscrews or extensions will fit into existing sets from different manufacturers. Instead of trying to match existing sets, we recommend that you consider replacing your existing interscrews entirely. This way you will be able to add extensions or obtain replacements later if required.
