Key Features

• John Deere hexagonal socket head flange screw, M6 x 20 (part 19M8649) designed for precise tensioning and reliable load distribution.
• Flange under the head provides even clamping force, reducing the need for separate washers and minimizing bolt head protrusion.
• Externally threaded fastener suitable for through-hole assemblies, with the ability to engage existing internal threads or form its own mating thread in compatible materials.
• Headed design enables tightening or releasing by turning the hex socket head, enabling controlled maintenance and serviceability.
• Metric M6 diameter with 20 mm length supports compact, high-precision joins common in agricultural equipment assemblies.
