Product Overview

5 Inch Structural Bolt


Looking for strong structural bolts that are easy to fasten and durable? Our SAE Grade 5 Medium Carbon Steel bolts are a perfect choice.

They have a 2 mil thick coating, which stays put even when the bolts are fastened to the maximum. The threading is hassle-free, and the coating is ACQ compatible, so it won't corrode when in contact with green treated lumber.

These structural bolts were crafted by industry experts to help resolve several problems, including chipping, peeling and cracking paint on the hardware. The unique military-grade, multi-stage electrolytically applied coating helps ensure that's not the case with these structured bolts.

This is a Pergola World-exclusive product, so rest assured that it offers the same hassle-free installation process all our products are known for. 

These are specialized, heavy hex bolts that can withstand large loads, making them ideal for applications in steel and wood construction.

Both 5-inch and 7-inch bolts have a coarse thread, are ½ inch diameter, and can accommodate rough sawn timber beam, 2 washers, and 2 brackets.
