Hillman Fasteners 811584 Galvanized Hex Bolts 3/8x3 in 50pk

Product Description

The HILLMAN FASTENERS 811584 is a 50-pack of Grade 2 galvanized hex bolts sized 3/8 inches in diameter by 3 inches in length. These machine bolts are engineered to join facing materials and resist shear movement across wood-to-wood, wood-to-metal, and metal-to-metal connections. The hot-dip or zinc galvanized finish provides corrosion resistance suited to general-purpose structural fastening. Licensed tradespeople and experienced installers use these bolts wherever a reliable, corrosion-resistant hex fastener is required. The Grade 2 rating covers a wide range of standard fastening loads in residential and light commercial construction.

These bolts are well-suited to general construction, framing, decking, equipment mounting, and similar structural applications. The 3/8-inch diameter and 3-inch length make them a common choice for connecting lumber members, attaching brackets, or securing metal hardware to wood substrates. Each box contains 50 bolts, and the package quantity from the supplier is 12 boxes per case, making this a practical option for contractors stocking a job site or supply room.

Installation Notes

Always pre-drill pilot holes sized appropriately for the 3/8-inch bolt diameter before driving these fasteners. Pair with washers and nuts of a similar grade and finish to avoid galvanic incompatibility and maintain joint strength. Power down or de-energize any equipment before fastening near electrical systems, and follow applicable building codes for structural connections. A standard 9/16-inch wrench or socket is typical for 3/8-inch hex bolt heads.
