STAINLESS STEEL SLOT ROUND WOODSCREWS DIN 96

Slot Round Woodscrews DIN 96 — DIN 96 is the oldest-style head profile in the woodscrew range — fully round, sitting entirely proud of the timber, driven with a flat slot rather than any cross-recess — and it's specified today almost exclusively for traditional and reproduction ironmongery, furniture restoration, and heritage fittings where matching the original screw's appearance matters more than driving convenience. Because the head doesn't countersink, it's used with fittings that have a plain clearance hole, such as period hinges, casement stays, and similar visible hardware, where the domed slotted head is itself part of the expected look. The standard fixes the same round head geometry as the Pozidriv equivalent, DIN 7996 — dome diameter and profile, shank taper, part-thread length — with a slotted recess taking the place of Pozidriv. Like other traditional patterns, the shank has a plain section below the head and thread only lower down, so the screw clamps the fitting down onto the timber rather than gripping along its full length. The slot's main drawback is practical: with only two contact points for the driver, it offers little resistance to cam-out, so it needs a well-fitted flat bit and more deliberate driving than a cross-recessed screw, particularly under power-tool torque. A2 (304-equivalent) covers the great majority of restoration and reproduction work comfortably. A4 (316-equivalent) is worth specifying for visible exterior ironmongery in coastal or persistently damp settings, since a domed, fully exposed head shows staining or pitting far more obviously than a countersunk or hidden fixing would. Size selection follows the fitting being matched — gauge to its clearance holes, and a length that leaves solid thread engagement in the timber without the point breaking through thinner sections.

FAQs
How does DIN 96 compare to the Pozidriv round head, DIN 7996?
The head shape is identical; DIN 96 uses a slotted drive while DIN 7996 uses Pozidriv, so the decision is really about matching existing period hardware versus wanting easier, faster driving.

Why is a round head specified rather than countersunk for period hardware?
Original hinges, catches, and similar ironmongery from before modern countersunk fixing conventions typically used plain clearance holes and proud, domed screw heads, so matching that appearance calls for a round rather than countersunk head.

Does DIN 96 need a countersunk hole?
No — it sits on top of a plain clearance hole in the fitting; a countersunk hole would let the domed head sink in unevenly and isn't the intended fit.

Is DIN 96 suitable for power-tool driving?
It can be driven with a power tool, but the slot offers minimal resistance to cam-out, so lower speed and a well-matched flat bit reduce the risk of the driver slipping and marking the visible head.
