Frame U-Bolt

Stainless steel U-bolts for NRS LoPro™ Frame Fittings and other frame accessories. Curve of the U-bolt is flattened, or "coined", to reduce impact on boat material. It's shaped to fit our 1-5/8" diameter frame pipe. The 2-1/8" deep Standard size U-bolt is used with LoPro Frame Fittings. The Oversized U-bolt is 2-5/8" deep. Tips of threaded shanks are rounded, eliminating sharp edges. Each U-bolt comes with two 1/2" zinc-coated nylon locknuts and two zinc-coated flat washers. Bolt thread is 5/16"-18.
