DIN 316 zinc plate screw, American form

DIN 316 is a fastener with an external thread and a curved head (in the shape of an “ear” or “butterfly”), which allows it to be tightened and loosened without the use of tools. This design greatly facilitates installation work and increases convenience during frequent assembly and disassembly operations.

Scope of application: used in assemblies that require regular adjustment, periodic assembly and disassembly, or quick access without tools.

Material: steel.

Coating: zinc plate protects against corrosion if the fastener is to be used in aggressive environments.
