This pack contains 1 x Boimet 3i Gold-Tite Square UniScrew Ref: UNISG. This screw is used for external hexed only and has a square slot in it. Like new. Packaging maybe damaged but not opened. If you purchased this product in 2013 it would have cost as much as RRP £52.80 (INCL VAT). All our stock comes from people like you and me that have drawers full of left over implant parts and are happy to part with them for less.
