BLACK INTERSCREWS ARE OUT OF PRODUCTION ... please ORDER NOW while stocks are still available.
Black Chicago interscrews (also referred to as screw posts, book screws, mating screws or ledger screws) are used in making post-bound photo albums and books, menus, folios, swatchbooks, and 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 15mm. Post diameter 5mm. Head diameter 10mm. Thread gauge M4.
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, then 10 to 60mm in 5mm increments.
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.
