WESTport hexalobe plug gages are fixed-limit GO/NO GO gages for verifying internal hexalobe drive recesses on surgical fasteners, bone screws, and implant components. The GO member confirms the recess accepts a correctly sized driver; the NO GO guards the upper limit so worn or oversized recesses are caught before assembly.
Built to standard or to your print
Manufactured to ISO 10664 hexalobular driving-feature sizes, or to your own patented or proprietary drive profile. Our engineering team is experienced across the full range of standard and custom hexalobe geometries.
