Replacement Tow Ball for 50mm Combination Pintle Hooks
Upgrade or replace your worn pintle hook components with this premium, Australian-made Heavy-Duty Replacement Tow Ball. Specifically engineered and tested by Couplemate™ Trailer Parts for 50mm combination pintle hooks, this high-tensile towing solution delivers a certified 3,500kg ATM rating for towing with vehicles under 5 tonnes. Featuring an anti-rotation flat shoulder and a low-profile half-nut design, it guarantees maximum thread engagement and an unyielding lock under demanding industrial conditions.
Product Features & Advantages
Worn towing components threaten safety and load stability on rough transit routes. This heavy-duty replacement ball restores safety compliance to your combination hitch setup:
- Australian Made & Tested: Proudly manufactured and rigorously evaluated by Couplemate™ to survive harsh commercial applications.
- Anti-Rotation Design: Engineered with a machined flat section on the shoulder to lock the tow ball securely against the pintle hook body, preventing the component from spinning during tightening or transit.
- Maximum Thread Engagement: Supplied with a specialised, low-profile locking half-nut to ensure optimal thread locking without compromising structural protrusion clearance.
- Universal Combination Fitment: Tailored directly to suit standard heavy-duty 50mm combination pintle hook assemblies.
Technical Specifications
To comply with safety benchmarks and prevent fastener thread stripping, over-stretching, or component detachment, this 32mm fine-thread shank must be installed using a calibrated manual torque wrench.• Target Installation Torque: 550 to 600 ft-lbs (745 to 813 Nm).Note: Do not use a standard impact wrench for final verification, as high-speed friction can trigger severe thread galling and false torque readings. Check and re-torque the half-nut after the first 100km of heavy service.
• Measure Your Hardware First: Commercial shank diameters vary across brands. Always measure your current pintle hook hole size and shank diameter prior to ordering to ensure an exact fit.
• Need Higher Capacity? If your commercial application requires a 4,500kg (4.5t) rating, do not use a 50mm configuration. View our 70mm Integral Ball Truck Pintle Hook (CTA-061572) to satisfy higher heavy transport capacities.
