Weld-on tie-down tabs create fixed anchor points for securing cargo with straps. For general trailer or fabrication use, the Fanmao 8-pack with 3-5/8-inch overall length is best for buyers who want a compact set of steel tabs; the longer Fanmao option suits buyers who need a 4-1/4-inch tab. The OTTFF slotted tabs offer a six-piece option, while the axle-specific OTTFF brackets are designed for welding onto a 3-inch round trailer axle. Compare the listed dimensions and intended mounting location before choosing.

Fanmao 8-Pack, 3-5/8-Inch Tabs
These Fanmao tabs are made from 1/4-inch low carbon steel and have a plain finish. Each measures 3-5/8 inches overall, with an inner height of 1-3/16 inches. The eight-piece set is a straightforward choice when a project needs multiple welded strap anchor points.
Best for: Buyers seeking a set of standard-size steel tabs for a trailer or fabrication project. The stated length and inner height make it easier to compare the tab with the available mounting space before welding.
Limitation: The finish is listed as plain, so buyers who need a particular coating or corrosion protection should plan for that separately. Confirm the dimensions suit the intended strap and installation location.
Fanmao 8-Pack, 4-1/4-Inch Tabs
This eight-pack uses low carbon steel with a plain finish. Its 4-1/4-inch overall length is longer than the other Fanmao tab in this guide, while its inner height is 1-1/8 inches. These dimensions help distinguish it from shorter tabs when planning anchor-point placement.
Best for: Buyers who prefer a longer tab and need several tie-down points. Choose this option if its 4-1/4-inch length fits the intended layout better than a shorter anchor.
Limitation: The listing does not provide a steel thickness in the supplied product details. Check the full product information and confirm the tab dimensions and application requirements before purchase.
Fanmao Tabs with Pre-Punched Holes
These Fanmao tabs are made from low carbon steel and have a plain finish. The listing gives an overall size of 3-1/2 by 2 inches and a D-ring size of 1-11/16 inches long by 1-1/4 inches wide. Pre-punched holes are specified for a 5/8-inch bolt.
Best for: Buyers whose design calls for the listed D-ring dimensions and a pre-punched bolt opening. The hole can be useful when a project requires a bolted component in addition to a welded mounting tab.
Limitation: The listed hole size is specific to a 5/8-inch bolt. Verify the bolt and mating hardware dimensions rather than assuming other sizes will fit.
OTTFF 6-Pack Slotted Tie-Down Tabs
OTTFF supplies six slotted tie-down tabs made from low carbon steel. They have a plain finish, measure 2-3/8 inches wide by 3-1/2 inches high, and are 1/4 inch thick. The listed dimensions are useful for checking clearance and placement during a build.
Best for: Buyers who want slotted anchor points and a six-piece quantity. Choose this set when its width, height, and thickness match the planned mounting surface and strap arrangement.
Limitation: The supplied details do not state the slot dimensions. Check the product information to confirm that the opening accommodates the hardware or strap planned for the project.
OTTFF Axle Tie-Down Brackets
This four-piece OTTFF set is described as weld-on axle tie-down tab brackets for a 3-inch round trailer axle. The brackets are low carbon steel with a plain finish and a stated thickness of 7/32 inch. Their axle-specific description separates them from general flat-surface tabs.
Best for: Buyers planning tie-down points on the stated 3-inch round trailer axle. Choose this option when the axle shape and listed thickness align with the installation plan.
Limitation: The supplied details identify a specific axle size. Avoid choosing it for a different axle dimension without confirming fit and suitability with the manufacturer or a qualified fabricator.
Buying Guide: How to Choose Weld-On Tie-Down Tabs
Which dimensions should you compare?
Check overall length, width, inner height, thickness, and any slot or hole measurements. These determine whether a tab fits the mounting area and the intended strap, bolt, or attachment hardware. The Fanmao options list different lengths and inner heights, while the OTTFF slotted set specifies width, height, and thickness.
Should you choose a general tab or an axle bracket?
Choose a general tab for a project where the mounting surface and layout are not restricted to a particular axle shape. Select an axle-specific bracket only after confirming that the axle matches its stated 3-inch round size. Do not treat a specialized bracket as interchangeable with a flat mounting tab.
How many tabs do you need?
Count the anchor points required for the cargo or fabrication layout, then compare that number with the package quantity. The products here come in sets of four, six, or eight. Consider whether the project needs matching points in multiple locations and whether the selected tab dimensions fit each location.
What should you check before welding?
Confirm that the tab, mounting surface, and attachment hardware are appropriate for the intended use. Review the complete product specifications, including any missing hole or slot dimensions. Welding and cargo restraint involve safety risks; use suitable fabrication practices and have the installation assessed by a qualified professional when needed. A plain finish does not specify a protective coating.
Frequently Asked Questions
What are weld-on tie-down tabs used for?
They provide welded attachment points for securing straps or other compatible hardware. The correct design depends on the mounting surface and attachment method.
Are all weld-on tabs the same size?
No. The products listed here have different lengths, heights, widths, thicknesses, and openings. Compare the stated measurements with your project before buying.
Can a tab with a pre-punched hole take any bolt?
No. The Fanmao tab with pre-punched holes specifies a 5/8-inch bolt. Verify the bolt size and fit rather than assuming the opening is universal.
Are axle tie-down brackets suitable for every trailer axle?
The OTTFF axle brackets are listed for welding onto a 3-inch round trailer axle. Confirm the axle dimensions before selecting them.
Does a plain finish mean the tab is corrosion-protected?
The product details identify a plain finish but do not specify a protective coating. Check the complete listing and determine whether additional protection is appropriate for the project.
