Osculati A2 AISI 304 Stainless Steel Split Cotter Pins DIN 94 / UNI 1336

Osculati split cotter pins are manufactured from A2 (AISI 304) stainless steel and are listed according to DIN 94 / UNI 1336. These mechanical retaining pins feature a looped head and two parallel legs that can be spread apart after installation to help prevent the pin from withdrawing from its mounting hole.

The split pin is inserted through a suitably sized hole in a shaft, clevis pin, bolt or other compatible fastening component. Once positioned, its two legs are bent apart to retain the assembly. The looped head helps prevent the pin from passing completely through the hole.

Split cotter pins are commonly used with castellated nuts and drilled bolts, as well as with compatible clevis pins and mechanical linkages. They provide a simple method of retaining components without requiring a threaded locking element.

Unlike solid clevis pins, DIN 94 split pins are intended to be deformed during installation. For reliable retention, a previously bent or damaged split pin should be replaced rather than repeatedly straightened and reused.

A2 (AISI 304) stainless steel provides corrosion resistance for general indoor, outdoor and suitable marine applications. For prolonged saltwater exposure or environments with high chloride concentrations, the suitability of the material should be assessed.

The Osculati A2-94 range includes 10 dimensional variants, with nominal diameters from 1.5 to 5 mm and lengths from 25 to 60 mm. Each version has an individual Osculati part number and is supplied in a cardboard box containing 25, 50 or 100 split pins.

Size Selection

Select the appropriate nominal diameter and length according to the mounting hole and the dimensions of the components being secured. The split pin should pass through the intended hole and provide sufficient leg length for proper bending and retention.

Available lengths depend on the selected diameter. Each dimensional variant has a fixed box quantity, as shown in the table above.

The exact dimensional tolerances and recommended mounting hole sizes are not specified in the supplied catalogue information.
