Tnisesm Blue Billet Aluminum Battery Hold-Down Bracket with 8-Inch J-Bolts
Product description
The blue anodized aluminium crossbar and stainless steel J-bolts provide a solid way to secure a battery with the specified width. The bracket is designed for batteries 175 mm wide or narrower, with fit depending on matching the stated measurements. Would a strap-style tie-down suit your setup better? This kit is a more specific choice when its bracket dimensions and hardware match the battery area.

The product listing names a range of battery group sizes, including 24, 27, 34, 35 and H6 (48), among others. Treat those as a starting point rather than a substitute for measuring: group labels alone do not confirm that a particular battery and installation will match this bracket’s width and bolt spacing. The listed parcel dimensions and weight describe the package, not the bracket’s fit dimensions.
Who it’s for
This Tnisesm bracket may suit someone replacing a battery hold-down or assembling a setup where a crossbar and two J-bolts are appropriate. It makes sense if your battery is no wider than 175 mm and the 190 mm bolt-centre spacing works for your installation. The blue anodized finish also gives the crossbar a distinct colour, while the stainless-steel bolts and supplied protective pieces form part of the hardware set.
Compared with a basic strap-based approach, this kit is built around a rigid crossbar and hooked bolts. That makes matching the actual battery and mounting arrangement especially important, a strap or another bracket style may be more suitable if this set’s dimensions do not line up. You may want to skip it if your battery exceeds the stated width or you cannot confirm that the bracket and bolts will fit your setup.
What you get
The package includes one battery hold-down bracket and two 8-inch J-hooks. It also comes with two hex nuts, two butterfly nuts, two rubber protective sleeves, two protective rubber washers, two spring lock washers and two flat washers. The supplied components give you the bracket and listed fastening hardware together, rather than just a replacement crossbar. Check that the included arrangement suits your installation before fitting, no additional tools or installation steps are specified in the product information.
What to clarify
Which battery sizes are listed as suitable? The listing names many groups, including 21, 24, 25, 27, 34, 35 and H6 (48). It also states a maximum battery width of 175 mm, so measure your battery instead of relying only on its group number.
How should the bolt spacing be checked? The distance between the J-bolt centres is 190 mm (7.48"). Compare that measurement with the available fit in your battery hold-down area before choosing the bracket.
What are the J-bolt dimensions? Each supplied J-hook is 200 mm (8") long. The product details do not give adjustment range or installation instructions, so the listed length is the useful comparison point when assessing fit.
Buying verdict
This kit is worth considering when its 175 mm width limit, 218 mm crossbar length and 190 mm bolt spacing suit your battery and installation. Its main appeal is the combination of an anodized aluminium crossbar with stainless-steel J-bolts and the included washers, nuts and protective sleeves. If the measurements do not match, choose a hold-down with dimensions suited to your setup rather than relying on the listed battery groups alone.
