This is a 6-pack of brass 5mm interscrew sets 32IS05-6, containing 6 posts and 6 screws with a 5mm post length.

Brass 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, etc. Made from genuine brass (not simply brass-coloured metal) 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 M4.


Our brass interscrews are available in 5mm increments in sizes from 5mm up to 60mm, and can be lengthened further with the use of extension posts. Interscrews in 5mm, 10mm, 15mm and 20mm lengths feature ONE-PIECE posts. These are complete sets, including both the post (the body, or female end) and the screw (the head, or male end). Lengths 25mm and longer feature two-piece posts made up using short brass post-and-screws with zinc-coated steel extensions.

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

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.
