L&H Threaded Rods
L&H Threaded Rods Corp. is a threaded rod and U-Bolt manufacturer located in Dayton, Ohio. We have been under the ownership of Mr. John C. Gray since 1978, when he moved the business from Muncie, Indiana to its current location in Dayton. Many of you are familiar with our people, our products, and our service in the heavy-duty truck repair industry, as we have been a staple in the aftermarket for several years. We take great pride in the quality of our products, and in the service we provide. Although our main product lines are threaded rods, U-Bolts, and U-Bolt kits, we also carry suspension-related parts like deep nuts, washers, spring center bolts, Hendrickson saddle bolts, steel lock nuts, and hex head cap screws. We also manufacture the patented "CENTERMARK" U-Bolt bender, which we feel is the best on the market.
