Key Features & Benefits
- Solid design — solid pin for applications where grease is applied externally during service intervals.
- 9/16″ x 3.5″ diameter — matches standard Australian trailer shackle plates with 1/2″ bolt holes. The UNF thread ensures compatibility with standard nyloc nuts.
- High tensile steel — manufactured from high tensile steel to withstand the constant pivoting loads that shackle pins endure during towing over rough roads.
- Includes nyloc nut — self-locking nyloc nut prevents the pin from backing out under vibration, maintaining a secure connection.
When to Use This Pin
Use the R5205 solid shackle pin when replacing worn pins on trailers that are serviced regularly and where external greasing is part of the maintenance routine. If you prefer low-maintenance operation, the R5205A greaseable version allows lubrication via a grease nipple.
