STAINLESS STEEL HEXALOBULAR PAN POLYTECH 30

Hexalobular Pan Polytech 30 — Hexalobular drive's six-lobed recess grips the driver bit more positively than a cross-head pattern, which is why this pan-head screw is often the default specification on automated or high-speed plastic assembly lines rather than hand-built runs. The pan head bears fully on the plastic surface, spreading load without needing a flush finish, and the Polytech 30 thread profile forms its own mating thread into a pilot hole as the screw is driven — no pre-tapped boss, moulded thread, or insert required. That combination suits enclosure and housing assembly, control gear, automotive interior trim, and any high-volume production environment where consistent torque and minimal cam-out across thousands of cycles matter more than driver familiarity. Because hexalobular resists slipping so well, it also tends to hold up better than Pozi or Phillips when a screw needs periodic removal and re-driving during servicing or rework, since a rounded recess is one of the more common causes of a stripped or unusable screw head. Polytech 30 is PTS's more broadly applicable thread-forming range; where an existing design specifies the alternative Polyfix 45 thread, or where trial fixing into a particular boss shows poor engagement or splitting, that's the point to review which range suits the plastic and boss combination rather than simply changing head or drive type. There's no single ISO or DIN standard covering the thread-forming profile itself, since it's an application-specific design for plastic rather than a generic machine screw thread, though the pan head and hexalobular recess follow the same general geometry used on ISO metric machine screws elsewhere in PTS's range. Grade choice again comes down to the assembly's destination: A2 (304-equivalent) is the sensible default for indoor enclosures and general appliance work, while A4 (316-equivalent) earns its keep on outdoor, marine, or washdown products where corrosion at the head could eventually mark or stress the surrounding plastic.

FAQs
Does hexalobular drive need a special bit, or will a standard Torx-type driver work?
A standard hexalobular (Torx-type) driver or bit matching the screw's size works; no proprietary tooling is needed, which is one reason it's a practical upgrade from Pozi or Phillips on lines that already stock hexalobular bits for other fasteners.

Is it worth switching an existing Pozi or Phillips line over to hexalobular?
Where cam-out, rounded heads, or inconsistent driving torque have been a recurring issue on powered or automated assembly, switching to hexalobular is usually worth trialling; for low-volume or hand-driven work the practical benefit is smaller and may not justify a change.

Does this screw form its own thread, or does the plastic need tapping first?
It forms its own mating thread directly in a correctly sized pilot hole as it's driven in, in the same way as the rest of the Polytech 30 range, so no separate tapping or thread insert is needed.

How does the Hexalobular Pan compare with the Hexalobular Countersunk Polytech 30?
Both share the same recess and thread-forming action; the head differs, with pan sitting proud on a flat bearing face and countersunk seating flush within a matching chamfered hole.
