Osculati AISI 316 Stainless Steel Fully Threaded Hex Head Bolts DIN 933 / UNI 5739

Osculati fully threaded hex head bolts are manufactured from AISI 316 stainless steel and are listed according to DIN 933 / UNI 5739. They feature an external hexagonal head and a metric threaded shaft for fastening compatible marine fittings, structural brackets, equipment components and mechanical assemblies.

The hexagonal head allows installation and removal using a correctly sized wrench or socket. The fully threaded design provides continuous threading along the shaft beneath the head, allowing the bolt to engage with compatible metric nuts or tapped holes.

Unlike partially threaded bolts, DIN 933 hex head bolts do not feature an extended unthreaded shank. This makes them suitable for fastening arrangements requiring threaded engagement along the available shaft length.

AISI 316 stainless steel provides corrosion resistance for suitable marine, outdoor and general mechanical applications. The material is commonly selected for equipment exposed to moisture, although the suitability of the fastening assembly depends on the installation environment, loading conditions and contact materials.

The range includes 34 dimensional configurations covering six nominal metric thread sizes: M4, M5, M6, M8, M10 and M12. Available bolt lengths range from 12 to 120 mm, depending on the selected diameter. Each variant is supplied in a box containing a specified number of bolts.
