above: interscrews, assembled and unassembled.
below: interscrew posts in 5mm increments from 10mm up to 60mm.

We carry a wide range of interscrews and extension posts. These are also often referred to as post-and-screw sets or ledger screws. Made of high quality brass, these interscrews have knurled heads which can be easily tightened and loosened by hand for convenience and to avoid burring which happens with slotted heads; alternatively a locking key is available.

Our interscrews are available in 5mm increments in sizes from 10mm up to 60mm, and each set includes both the post (body) and the screw (head). Post diameter is 5.5mm. They are supplied in bar-coded and labelled hang-sell bags of 2, or otherwise loose-packed or in boxes of 100.

Extension posts are also available in 10mm and 20mm lengths, and these can be used to fit between the post and screw in order to increase the length if required, or added in at a later date.

These screws available in bar-coded hang-sell packs of 2, or bulk boxes of 100 loose pieces:

Variables such as length, diameter, thread length and thread 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 set with our interscrews; that way you will be able to add extensions or obtain replacements later if required.
