Description

Overview

SAF Holland Weld In King Pin 50mm suits trailers that run an 8mm skid plate and need a genuine weld-in kingpin for a fifth wheel turntable. It gives you a proven coupling interface so the prime mover locks in cleanly. Correct selection matters because skid plate thickness and rating affect service life and safety.

Features

This weld-in kingpin supports workshop rebuilds where you replace a worn or damaged pin rather than swapping the whole skid plate assembly. The mushroom style head helps maintain consistent engagement in compatible fifth wheels when the skid plate and weld prep are correct.

• 50mm weld-in kingpin format for fifth wheel skid plates
• Rated to 151kN D value for heavy-duty coupling loads
• Designed to suit 8mm skid plate thickness
• Specified with CRN 16672 for identification and compliance checks

Specifications and Materials

Part number: TT4444.
SAF selects metallurgical properties for each kingpin application to balance strength, hardness, and impact resistance. A genuine replacement helps you restore the original coupling design intent during turntable servicing.

Compatibility and Fitment

Confirm your turntable uses a 50mm weld-in kingpin and that the skid plate thickness matches the specification before you start any welding work. This cross-reference listing means this part is a suitable replacement for the part numbers and applications shown. Some changes in installation may be required. KPT809EF, KP-T-809-EF

Compliance and Safety

Kingpins and skid plates are safety-critical components, so a qualified heavy-vehicle workshop should carry out welding and inspection. Treat the SAF Holland Weld In King Pin 50mm as a rated coupling component and confirm the 151kN D value suits the vehicle and trailer combination. Incorrect fitment can cause accelerated wear or coupling issues.

Trailer Applications

For example, fit this kingpin to semi-trailer and dolly skid plates that use a 50mm coupling standard and an 8mm plate thickness. Fleet maintenance teams also use the SAF Holland Weld In King Pin 50mm during turntable overhauls where the kingpin surface shows wear, scoring, or deformation.
