Brand: WSM

These U-Bolts are made in the U.S.A. from high quality 304 Stainless Steel, and they hold up well in wet outdoor environments, and salt water exposure. This package includes (4) Stainless Steel U-Bolts, and high quality stainless steel hardware consisting of (8) flat washers, (8) lock washers & (8) hex head nuts. The width is the Inside measurement between the "Legs" of the U-Bolt, the Length (Height) is the inside dimension measurement from the tip of the "Leg", to the inside face of the "U". When calculating the length/height of the U-Bolt needed, add 1" for the nut height, to your clamping distance. To reduce the risk of "galling" (aka "thread lock") use a 3/4" hand ratchet or wrench to install and tighten the nuts, do not use a high speed or impact socket driver.

Our U-Bolts are Pre-Waxed to prevent galling, when tightening.
