STAINLESS STEEL HEXALOBULAR RAISED COUNTERSUNK MACHINE SCREWS DIN 966TX

Hexalobular Raised Countersunk Machine Screws DIN 966TX — DIN 966TX carries the same flush-seating, domed-top raised countersunk head as the rest of the DIN 966 family, but with a hexalobular (TX-denoted) recess in place of a slot or Pozidriv cross — giving markedly higher torque capacity and virtually eliminating cam-out compared with either. That matters directly for the finish: because the domed top stays visible once installed, a driver that slips marks a surface that's meant to look neat, and hexalobular's greater contact area makes that far less likely than a cross-recess drive would allow, particularly under power tools. It's the natural choice for automated or high-volume assembly of visible, decorative fixings — furniture, fittings, and consumer hardware production lines wanting both a finished appearance and consistent, repeatable driving torque.

Head geometry and countersink requirements are identical across the DIN 966 drive variants — only the recess differs between DIN 966Z (Pozidriv), the slotted version, and this hexalobular TX variant — so the countersink hole doesn't change when switching drive type, only the driver needed to install it.

Where a specification calls for the internationally standardised equivalent rather than the DIN reference, ISO 14584 covers the same raised countersunk hexalobular geometry with formally fixed tolerances; the DIN 966TX designation remains in wide commercial use and the two are broadly interchangeable, though the specific cross-reference is worth confirming for critical assemblies.

A2 stainless suits most indoor decorative and furniture applications. A4 is the better choice for outdoor, coastal, or washdown-exposed fittings, since visible corrosion on an exposed domed head is both more likely with A2 in those conditions and more damaging to a finished product's appearance than hidden staining would be.

Match thread to the tapped hole, and specify DIN 966TX wherever powered or automated assembly of a visible fixing makes consistent, low-cam-out driving worth the modest cost step up from Pozidriv.

FAQs
How does DIN 966TX differ from DIN 966Z?
Both share the same raised countersunk head form; DIN 966TX uses a hexalobular drive recess, while DIN 966Z uses a Pozidriv recess. Head geometry and countersink requirements are the same; only the drive differs.

Does DIN 966TX require a different countersink hole than DIN 966Z?
No. The tapered seating portion of the head is the same across drive variants, so countersink angle and depth requirements are unchanged.

How does DIN 966TX relate to ISO 14584?
ISO 14584 is the internationally standardised equivalent of the same raised countersunk hexalobular geometry. Where a specification calls for ISO compliance rather than a DIN reference, quote ISO 14584, confirming the exact dimensional cross-reference for critical assemblies.
