Osculati A2 AISI 304 Stainless Steel Hex Socket Head Cap Screws DIN 912 / UNI 5931
Osculati socket head cap screws are manufactured from A2 (AISI 304) stainless steel and are listed according to DIN 912 / UNI 5931. These metric machine screws feature a cylindrical head with an internal hexagonal socket and are intended for fastening compatible mechanical components, equipment fittings and mounting assemblies.
The cylindrical socket head provides a flat bearing surface against the mounted component. Its internal hexagonal recess allows installation and removal using a matching Allen key or hex driver, making this head design useful where access for an external wrench is limited.
The metric threaded shaft is designed to engage with a compatible nut or internally threaded hole. These fasteners are machine screws rather than self-tapping screws and require a corresponding threaded connection.
A2 (AISI 304) stainless steel offers corrosion resistance for general indoor, outdoor and suitable marine applications. For installations involving prolonged saltwater exposure or high chloride concentrations, the suitability of the stainless steel grade should be assessed.
The range includes 25 dimensional configurations across four nominal thread sizes: M4, M5, M6 and M8. Available lengths range from 10 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.
