Assy 3/8" x 4" Galv B/L/F/N

The Assy 3/8" x 4" Galv B/L/F/N is a complete galvanized bolt assembly — 3/8-inch diameter by 4-inch length — including bolt, lock washer, flat washer, and nut, manufactured by Best Bolt & Nut Corp., available at Skipper B Trailers in Westwego, Louisiana. The 4-inch length is the mid-point of the 3/8-inch galvanized assembly range at Skipper B — long enough to reach through the moderately thick connections found throughout boat trailer and utility trailer construction, but not so long that excess thread extends past the nut. The 4-inch bolt handles fender bracket mounting through standard frame members, bunk board connections with spacers, guide post hardware through single-layer tubing, and the mid-depth connections that make up the majority of longer bolt applications on trailers across Southeast Louisiana.

Louisiana trailer owners who work on their own trailers know that the 4-inch bolt fills the gap between the standard short bolts (1-2 inches) that handle surface mounting and the extra-long bolts (5-6 inches) needed for the deepest connections. Many trailer repair and maintenance jobs land right in the 3-4 inch range — replacing a fender bracket that passes through a frame rail and a spacer, mounting a bunk board through a crossmember with carpet padding, or securing a component through doubled material. The galvanized finish handles the corrosive marine environment at Bayou Segnette State Park, Lake Pontchartrain, and the launches across Jefferson Parish and the Greater New Orleans West Bank, and the complete B/L/F/N assembly provides the flat washer, lock washer, and nut matched to the bolt so every connection goes together correctly. The lock washer is especially important at the 4-inch length — longer bolts flex more under the road vibration from Interstate 10, Highway 90, the Westbank Expressway, and the rough roads between Westwego, Marrero, Harvey, and Gretna, and the lock washer prevents the nut from backing off. Whether you're Fishing Fanatic Frank doing a weekend maintenance session on his Magic Tilt, a marine repair shop keeping the full assembly range stocked for efficient service, a DIY mechanic replacing corroded mid-length bolts, or any trailer owner who needs the 4-inch reach with complete hardware, this assembly has it covered.

At $2.89, this complete galvanized assembly provides the 4-inch reach with all matching hardware. Part of Skipper B's full range of 3/8-inch galvanized assemblies from 1.5" to 6". Perfect for fender brackets, bunk mounting, guide post hardware, mid-depth frame connections, and general trailer maintenance throughout Southeast Louisiana.
