Metric DIN 923 slotted pan head screws with shoulder are machine screws with a slotted drive pan head (raised cheese head) with a unthreaded shoulder directly below the head. The head and shoulders have a wider diameter than the threaded portion. This unique design makes them ideal to function as shafts for rotating bushings and bearings as well as maintaining alignment in component assembly. Aspen Fasteners offers one of the most complete ranges of metric screws and other inch and metric industrial fasteners for immediate delivery from stock. The following sizes of DIN 923 slotted pan head screws with shoulder are available for immediate shipping from stock: Diameters ranging from M2 to M10 with lengths up to 25mm in stainless steel 303.

DIN (Deutsches Institut f?r Normung - German Institute for Standardization) standards are issued for a variety of components including industrial fasteners as Metric DIN 920 slotted pan head screws with small head. The DIN standards remain common in Germany, Europe and globally even though the transition to ISO standards is taking place. DIN standards continue to be used for parts which do not have ISO equivalents or for which there is no need for standardization.

1) Mechanical properties of stainless steel for metric DIN 923 Slotted Pan Head Screws with Shoulder

Stainless steels can be divided into three groups of steel - austenitic, ferritic and martensitic. Austenitic steel is by far the most common type (>90% of commercial fasteners). The steel groups and strength classes are designated by a fourdigit sequence of letters and numbers (eg A2-70) as shown in the following table. DIN EN ISO 3506 governs screws and nuts made from stainless steel.
