SR03 - 7/8" x 3 1/4" Inside Width (Fine Thread)

7/8"Our UBolts are Fine Thread (SAE 7/8-14). When ordering your UBolt, the diameter you order will be the diameter of the threads. The un-threaded portion of the UBolt is approx 1/64 to 3/64 smaller in diameter.

3 1/4"Inside Width (we bend around a die this size). Some ubolts will measure slightly wider due to the rod material. When you properly torque the ubolt, normally they will tighten in to the width chosen. U-Bolts must be tightened and torqued properly at max torque of 500 ft lbs using a cross pattern sequence.

Selected Inside Length. This measurement can vary by 1/4" to 1/2".
