Knurled Interscrews

Knurled Interscrews.(serrated)

These are the finest quality interscrews available. Our interscrews have a relatively flat head with serrations around the outside which enable the interscrew to be easily tightened by hand or secured with a locking key. The locking key fits over top of the serration and allows for extra tightening.

Sizes up to and including 20mm are manufactured from solid brass in one piece plus the screw. For sizes larger than 20mm, as a cost saving measure, we have introduced a 3 part system which involves a 5mm solid brass base plus screw and an appropriate extension to make up to the length required.
