Osculati A2 AISI 304 Stainless Steel Phillips Raised Countersunk Machine Screws DIN 966 / UNI 7689
Osculati raised countersunk machine screws are manufactured from A2 (AISI 304) stainless steel and are listed according to DIN 966 / UNI 7689. They feature a raised countersunk head, a cross-recessed drive and a metric threaded shaft for fastening compatible mechanical components and fittings.
The head combines a tapered underside with a slightly convex upper section. The tapered portion fits into a matching countersunk recess, while the rounded top remains raised above the mounting surface. This provides a different appearance from a flat countersunk screw, whose head is intended to sit flush with the surface.
The cross-recessed drive allows installation and removal using a matching Phillips screwdriver or driver bit. The metric thread is designed to engage with compatible nuts or internally threaded holes, making these screws suitable for a variety of mechanical fastening applications.
Unlike DIN 7983 self-tapping screws, DIN 966 machine screws are not designed to cut their own threads into the mounting material. Their installation requires a compatible threaded connection.
A2 (AISI 304) stainless steel offers corrosion resistance for general indoor, outdoor and suitable marine applications. For prolonged saltwater exposure or environments with high chloride concentrations, the suitability of this stainless steel grade should be assessed.
The range includes 20 dimensional configurations across four nominal metric thread sizes: M3, M4, M5 and M6. Available lengths range from 16 to 60 mm, depending on the selected thread size. Each version has an individual Osculati part number and is supplied in a cardboard box containing a specified number of screws.
