This is a 6-pack of brass 25mm Chicago interscrews 32IS25-6 containing 6 posts and 6 screws with a 25mm post length.
Brass Chicago interscrews (also referred to as screw posts, book screws, mating screws or ledger screws) are used in making post-bound photo albums, scrapbooks, menus, folios, material swatch books, and as joiners in leatherwork.
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 25mm (one inch). Post diameter 5mm. Head diameter 10mm. Thread M4.
Brass interscrews are available in 2mm, then 5mm to 80mm in 5mm increments, and can be lengthened further with the use of extension posts.
Interscrews up to 20mm feature ONE-PIECE posts. Interscrews 25mm and longer feature TWO-PIECE posts made up using short brass posts with zinc-coated steel extensions.
Extension posts are available in 7mm, then 10 to 60mm in 5mm increments.
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.
