Osculati DIN 965 / UNI 7688 machine screws are manufactured from A2 (AISI 304) stainless steel and feature a flat countersunk head with a cross-recessed drive. The tapered head is designed to sit flush within a matching countersunk recess, while the metric threaded shaft engages with compatible nuts or tapped holes. AISI 304 stainless steel provides corrosion resistance for general mechanical assemblies, equipment installations and suitable marine applications. The range includes 36 dimensional configurations across five metric thread sizes from M3 to M8, with lengths from 12 to 80 mm. Each variant is supplied in a cardboard box containing 10, 25, 50, 100 or 200 screws, depending on the selected size.

Osculati A2 AISI 304 Stainless Steel Phillips Flat Countersunk Machine Screws DIN 965 / UNI 7688
Osculati flat countersunk machine screws are manufactured from A2 (AISI 304) stainless steel and are listed according to DIN 965 / UNI 7688. They feature a flat countersunk head, a cross-recessed drive and a metric threaded shaft for fastening compatible mechanical components, fittings and equipment assemblies.
The flat countersunk head has a tapered underside designed to fit into a matching countersunk recess. When correctly installed, the head can sit flush with the mounting surface, providing a smooth finish without a protruding screw head. This design is useful where a level surface is required or where an exposed screw head could interfere with adjacent components.
The cross-recessed drive allows installation and removal using a compatible Phillips screwdriver or driver bit. The metric threaded shaft is designed to engage with a matching nut or internally threaded hole, providing a removable mechanical fastening connection.
Unlike DIN 7982 self-tapping screws, DIN 965 machine screws are intended for use with compatible pre-threaded connections rather than for forming their own threads in the mounting material. They also differ from DIN 966 machine screws, which feature a raised countersunk head with a rounded upper surface.
A2 (AISI 304) stainless steel provides corrosion resistance for general indoor, outdoor and suitable marine applications. For installations involving continuous saltwater exposure or high chloride concentrations, the suitability of the stainless steel grade should be assessed.
The range includes 36 dimensional configurations across five nominal metric thread sizes: M3, M4, M5, M6 and M8. Available lengths range from 12 to 80 mm, depending on the selected thread diameter. Each version has an individual Osculati part number and is supplied in a cardboard box with a specified quantity.

Size Selection
Select the required nominal metric thread size and screw length according to the components being fastened. Ensure that the screw is compatible with the corresponding nut or tapped hole and that the mounting surface accommodates the flat countersunk head.
Available lengths vary by thread size. Each dimensional configuration has a fixed box quantity as indicated in the table above.
The exact thread pitch, drive recess size, strength class and countersink dimensions are not specified in the supplied catalogue information.
