STAINLESS STEEL POZI RAISED COUNTERSUNK WOODSCREWS DIN 7995

Pozi Raised Countersunk Woodscrews DIN 7995 — A raised countersunk woodscrew carries a domed top above the same countersunk base as a standard countersunk screw, so once driven it sits slightly proud rather than flush — the pattern specified whenever the fixing is meant to be seen as part of the finished piece, such as door and window furniture, decorative hinges, and cabinet hardware, usually paired with a cup washer that nests around the countersunk cone and supports the dome. DIN 7995 is the standard that fixes this geometry: head diameter and countersink angle, the dome profile above it, shank taper, and the Pozidriv recess dimensions, so screws from different suppliers match the same cup washers and driver bits. Like the fully flush DIN 7997 pattern, it has a plain shank below the head and thread only on the lower portion, drawing a top component — typically the hardware being fixed — down onto the timber as it's driven, rather than gripping along its full length. Pozidriv is the mid-ground drive choice here: it holds the bit far better than a slotted screw under torque without the added cost of a hexalobular recess, which matters less on decorative fixings driven by hand or a light power tool than it does on high-volume trade work. On grade, A2 (304-equivalent) is the right specification for the great majority of furniture, cabinetry, and interior hardware fixing this screw is used for. A4 (316-equivalent) becomes worthwhile mainly where the fitting sits somewhere genuinely damp or coastal — exterior door and window furniture near the sea, for instance — since visible screws in a decorative application show surface staining or pitting far more obviously than a hidden fixing would. Sizing follows the hardware being fixed: match the shank gauge to the screw holes in the fitting, and choose a length that seats the dome properly in a cup washer while leaving solid thread engagement in the timber beneath.

FAQs
Is a cup washer necessary with DIN 7995, or can it be used without one?
No — the screw seats perfectly well directly into a countersunk hole without a washer. A cup washer is an optional addition used mainly for appearance, to protect the timber surface, or to allow the screw to be removed and refitted without re-cutting the countersink.

How does DIN 7995 compare to the fully round head pattern, DIN 7996?
DIN 7996 has no countersunk base at all — its domed head sits entirely proud and suits fittings with a plain clearance hole, such as hinges, rather than a countersunk recess. DIN 7995 keeps the countersunk base of a standard screw and only adds the dome on top.

Does DIN 7995 need pre-drilling?
Softwood generally doesn't need it thanks to the screw's sharp point and thread form, but hardwood and denser timber benefit from a pilot hole to prevent splitting, particularly where the fixing sits close to a timber edge or corner.

Can DIN 7995 be specified for exterior door and window furniture?
Yes, particularly in A4 stainless where the fitting faces coastal or persistently damp conditions; for general exterior use away from the coast, A2 is normally the right and more cost-effective specification.
