This is a 6-pack of matt black 20mm Chicago interscrews 32IS20B-6 containing 6 posts and 6 screws with a 20mm post length.

Black Chicago interscrews (also referred to as screw posts, book screws or ledger screws) are used in making post-bound photo albums and books, menus, folios, swatchbooks, as well as joiners in leatherwork.

Made from black zinc electroplated genuine brass and therefore ideal for archival use, these high quality interscrews have knurled heads which can be easily tightened and loosened by hand for convenience and to avoid burring.

DIMENSIONS

Post length 20mm. Post diameter 5mm. Head diameter 10mm. Thread gauge M4

ALSO AVAILABLE

Our black interscrews are available in 5mm increments in sizes from 5mm up to 20mm, and can be lengthened further with the use of extension posts

Extension posts are available in 7mm, 10mm, 15mm, 20mm, 30mm, 40mm, 50mm and 60mm lengths. These can be used to extend the interscrews, for instance if extra pages are added to an album.

Our interscrews are also available in brass and silver finishes.

WHAT'S WHAT IN INTERSCREWS

Interscrew components at The Photo Album Shop

Variables such as length, depth, diameter, thread length and pitch mean that it is 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.
