Hillman Fasteners 240324 Carriage Bolt 1/2-13x5 in 25 Pack

Product Description

The HILLMAN FASTENERS 240324 is a 1/2-13 x 5 inch steel carriage bolt sold in a 25-pack. It features a round head with a square neck that bites into the material surface on installation, preventing rotation without a wrench on the bolt side. The coarse thread pattern provides strong holding power in wood, structural framing, and general fabrication applications. These bolts are installed by licensed tradespeople and general contractors wherever a tamper-resistant, flush-head fastener is required. The steel construction delivers reliable tensile strength for load-bearing connections.

Carriage bolts in this size range are commonly used in wood-to-wood and wood-to-metal connections in residential and light commercial construction, including deck framing, post connections, pergola structures, and equipment mounting. The 1/2-13 thread designation indicates a 1/2 inch nominal diameter with 13 threads per inch, a standard coarse-thread specification that mates with standard hex nuts and washers. Sold in a 25-pack, this quantity suits service vehicles, job-site supply bins, and maintenance inventory.

Installation Notes

Carriage bolts are typically installed by carpenters, ironworkers, or general tradespeople working to applicable building codes. Pre-drill a hole matching the bolt diameter through all mating materials before driving the square neck flush with a mallet. Always use a washer and nut on the through side and torque to the specification required by the applicable structural design. Never install without confirming material thickness supports the full square-neck embedment.
