Description

Overview

King Pin Block with Bolts 3/4UNF supports a bolted king pin mount on a skid plate for fifth wheel coupling. It provides a stable mounting interface for service replacement where the skid plate setup uses 3/4UNF fasteners. As a result, you can restore coupling security while keeping the existing turntable layout.

Features

King Pin Block with Bolts 3/4UNF is designed for simple, bolt-on serviceability during repairs and rebuilds.

• 3/4UNF fastener thread for bolting to a skid plate
• Supplied with bolts for a complete mounting set
• Supports bolt-in king pin mounting layouts used on many turntable assemblies
• Helps maintain a secure king pin interface during coupling and uncoupling

Specifications and Materials

Part number: TT4444K.
This listing covers the king pin block and bolts only. Confirm the required bolt grade and tightening torque from the skid plate or king pin manufacturer before installation. See SAF-HOLLAND kingpin technical brochure for general kingpin mounting guidance

Compatibility and Fitment

Use this king pin block when your skid plate specifies a bolted 3/4UNF king pin mount. Confirm the mounting pattern and plate thickness on your trailer before ordering, because skid plates can vary between builds. Install and torque fasteners using the correct procedures so the king pin remains square to the skid plate. 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. SS020-8, SS0208

Compliance and Safety

Treat king pin mounting hardware as safety-critical and use a qualified technician for replacement work. Inspect the skid plate and king pin area for wear, cracking, or damaged threads before refitting. Follow your maintenance schedule for coupling components and re-check fasteners as required after service.

Trailer Applications

King Pin Block with Bolts 3/4UNF suits turntable and fifth wheel couplings that use bolt-in king pin mounting. For example, it can apply to semitrailers, B-double trailers, and converter dollies with a skid plate and king pin arrangement. It also suits workshop repairs where you want to replace the mounting block without changing the skid plate assembly.
