This is a 6-pack of matt black 5mm Chicago interscrews 32IS05B-6 containing 6 posts and 6 screws with a 5mm 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.
Post length 5mm. Post diameter 5mm. Head diameter 10mm. Thread gauge M4.
WHAT'S WHAT IN INTERSCREWS
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.
