FAQs
What material are these U-bolts made of?
These U-bolts are made from high-tensile steel.
What is the thread size of these U-bolts?
They feature an M10 thread, which is 10mm in diameter.
What are the external dimensions of the U-bolt?
The internal width is 70mm, the total internal length is 100mm, and the threaded section is 30mm long.
Are nuts included with the U-bolts?
No, nuts are not included. They must be purchased separately, ensuring they are M10 size.
What is the purpose of the Gold plating?
The Zinc & Gold Plating provides a layer of protection against corrosion and rust, enhancing the durability and lifespan of the U-bolt.
Can these be used on automotive suspension systems?
Yes, they are suitable for many automotive and trailer suspension applications requiring secure fastening, provided the dimensions match.
How should I tighten the U-bolts?
Tighten the nuts evenly in a cross or star pattern to ensure uniform pressure distribution. Refer to specific application torque recommendations if available.
Troubleshooting
U-bolt does not fit the mounting holes.
Verify the internal width (70mm) and length (100mm) of the U-bolt against the required dimensions. Ensure you are not trying to fit it over a component wider than 70mm.
Nuts do not thread onto the U-bolt.
Confirm you are using M10 nuts. Check the U-bolt threads for damage or debris. Clean the threads gently if necessary.
Corrosion is appearing on the U-bolt.
While plated, prolonged exposure to harsh conditions can eventually lead to corrosion. Clean the area and consider applying a protective coating or wax designed for automotive/metal components.
U-bolt appears to be bending under load.
Ensure the U-bolt is not overloaded beyond its high-tensile strength rating. Check that all nuts are tightened evenly. If bending persists, the application may require a stronger U-bolt.
Pros and Cons
Pros
High tensile strength for secure and reliable fastening under load.
Durable plating offers excellent resistance to corrosion.
OEM grade quality ensures consistent performance.
Standard M10 thread is widely compatible.
Pack of two provides immediate usability for many common tasks.
Cons
Specific dimensions might not fit all applications without modification.
Threaded section length is fixed, limiting adjustment for very thick materials.
Gold finish may not be aesthetically suitable for all visible applications.
Not suitable for extremely heavy-duty industrial applications requiring larger bolt sizes.
Setup, Compatibility & Care
Setup:
Ensure the mounting surface and the item to be secured have aligned holes that match the U-bolt's internal width (70mm) and length (100mm).
Slide the U-bolt over the axle or frame component, passing the threaded ends through the designated mounting points.
Attach appropriate M10 nuts (sold separately) to the threaded ends. Tighten nuts evenly in a star or cross pattern to ensure uniform pressure.
Torque to manufacturer specifications or to a firm, secure fit appropriate for the application.
Compatibility:
Thread: Compatible with standard M10 nuts and washers.
Dimensions: Best suited for mounting items onto components with a width of up to 70mm and a thickness of up to 30mm (for the threaded section).
Applications: Commonly used for trailer axles, vehicle suspension, frame reinforcement, and general heavy-duty clamping.
Care:
Inspect U-bolts regularly for signs of wear, corrosion, or damage.
Clean with a damp cloth. Avoid abrasive cleaners that could damage the plating.
If rust appears, consider applying a rust inhibitor suitable for plated steel.
