Key Features & Benefits
- BSW thread — British Standard Whitworth thread is the traditional thread form used on Australian trailer hardware. Not interchangeable with UNF or metric bolts.
- 1/2″ x 2″ size — common size for trailer spring bracket bolts, body panel fixings and general structural connections.
- Nuts included — each bolt comes with a matching BSW nut for a complete fastening.
- Sold as a pair — two bolt-and-nut sets per pack.
When to Use These Bolts
Use the R5204AW for any trailer assembly task requiring 1/2″ BSW fasteners. Check your existing bolts before ordering — BSW thread is coarser than UNF and the two are not interchangeable. If you need shackle-specific bolts, see the R5201 shackle bolt instead.
