Best Deal Spring has got you covered when it comes to custom U-bolts and J-bolts. We can build custom u-bolts and j-bolts to any size and specification you need!

Top-Quality Materials for U-Bolts

The steel material we use is made specifically for U-bolts and J-bolts. It is high-quality, made-in-the-USA, and it is cold-drawn. This enables it to be bent into shape without the need for heating. The rods also have rolled-in threads rather than cut-in threads, which provides a more durable thread for long-lasting performance. The rods we use were designed specifically for U-bolts, unlike many other U-bolts out there that simply use whatever rod will function. Sizes 3/8" to 9/16" are a grade-5 equivalent, while sizes 5/8" to 1-1/4" are a grade-8 equivalent.
