Hillman Fasteners 240030 Carriage Bolt 1/4-20 X 2.5in 100 Pack

Product Description

The HILLMAN FASTENERS 240030 is a 1/4-20 x 2-1/2 inch steel carriage bolt sold in a 100-pack. It features a round dome head, a square neck that bites into wood or soft material to prevent spinning during tightening, and coarse-thread sizing. Carriage bolts are a standard fastener in structural wood assemblies, deck framing, equipment mounting, and general trade construction. This part is suited for contractors, carpenters, and field technicians who need reliable fasteners in quantity for repetitive installations.

This carriage bolt is used in residential and light commercial construction applications where a smooth, finished bolt head is required on the visible face of an assembly. Typical uses include deck ledger connections, post-and-beam framing, fencing hardware, and equipment anchoring to wood substrates. The 1/4-20 coarse thread is a widely used standard size compatible with 1/4-20 hex nuts and washers available from most fastener suppliers. Sold in a 100-count box, this pack quantity suits job-site use where volume and consistency matter.

Key Features

• 1/4-20 coarse thread for fast engagement and strong holding power in wood and structural applications
• 2-1/2 inch length accommodates typical double-layer wood assemblies and standard lumber thicknesses
• Round dome head provides a flush, snag-free finished surface on the bolt face
• Square neck under the head locks the bolt in place in wood, eliminating the need for a second wrench during installation
• Steel construction for strength in structural and general fastening applications
• 100-pack quantity reduces restocking frequency on active job sites

Compatibility

Designed as a standard 1/4-20 x 2-1/2 inch carriage bolt compatible with 1/4-20 hex nuts and flat washers for use in wood framing, deck construction, and general structural assemblies.

Installation Notes

Carriage bolts are installed by driving the bolt through a pre-drilled clearance hole and seating the square neck into the material to prevent rotation. A hammer or mallet is typically used to set the neck flush before threading the nut. Always use an appropriately sized washer and nut, and torque the nut with a wrench while the bolt head remains stationary. Follow applicable building codes for structural fastener requirements in load-bearing assemblies.
