Ronstan RF255 Transom Pintle – 6.4mm Stainless Steel Rudder Pin Fitting
Ensure secure and reliable rudder attachment with the Ronstan RF255 Transom Pintle—a high-quality marine-grade stainless steel fitting designed for dinghies, trailer yachts, and small keelboats.
This pintle forms the pivot pin connection between the rudder and gudgeon, allowing smooth, controlled steering while maintaining a strong and stable attachment. It is typically paired with a compatible gudgeon such as the RF254 or similar fittings.
Constructed from 316 stainless steel, the RF255 provides excellent resistance to corrosion, saltwater exposure, and general wear, ensuring long service life in demanding marine conditions.
The 6.4mm (1/4") diameter pin delivers a solid and dependable connection, while the cross-drilled design allows for retaining clips, helping keep the rudder securely in place during operation.
With a 4-hole mounting base, installation is straightforward and secure, making this fitting ideal for both new builds and replacement rudder hardware.
Compact, strong, and easy to install, the RF255 is a trusted solution for maintaining smooth steering performance and reliable rudder alignment.
