This is a 6-pack of brass 40mm Chicago interscrews 32IS40-6 containing 6 posts and 6 screws with a 40mm 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.
These high quality interscrews have knurled heads which can be easily tightened and loosened by hand for convenience and to avoid burring.
Post length 40mm. Post diameter 5mm. Head diameter 10mm. Thread M4.
Interscrews in 2mm up to 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.
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.
