Hillman Fasteners 240048 Carriage Bolt 1/4-20x4 in 100 Pack

Product Description

The HILLMAN FASTENERS 240048 is a 1/4-20 x 4 inch steel carriage bolt with a round head, square neck, and coarse thread pattern. Sold in a 100-count pack, this fastener is designed for structural and general-purpose fastening applications where a smooth, finished bolt head is required on the visible face of the assembly. The square neck locks the bolt in place against the mating material as the nut is tightened, preventing rotation during installation. At 35 pounds per box, this bulk pack is suited for contractors and tradespeople who work with large fastener volumes on the job site.

Carriage bolts in this size and thread spec are commonly used in wood-to-wood and wood-to-metal connections across residential and light commercial construction, deck framing, equipment mounting, and utility structure assembly. The 1/4-20 coarse thread engages quickly and resists cross-threading in field conditions. This 100-pack format reduces reorder frequency on active job sites and works well for shop stock.

Key Features

• 1/4-20 coarse thread for fast engagement and reliable hold
• 4 inch length suits moderate-depth structural connections
• Round dome head provides a clean, low-profile finished appearance
• Square neck prevents bolt rotation during nut tightening without requiring a wrench on the bolt head
• Steel construction for strength in structural fastening applications
• 100-count bulk pack reduces job-site reordering

Compatibility

Designed as a standard 1/4-20 coarse thread carriage bolt suitable for use with any standard 1/4-20 hex nut and compatible with wood, metal, and composite substrates where a round-head through-bolt connection is specified.

Installation Notes

Carriage bolts are typically installed by a carpenter, general contractor, or maintenance tradesperson. Drill a clean through-hole sized to the bolt shank diameter before installation to allow the square neck to seat and bite properly into the substrate. Tighten the mating nut from the threaded end using a wrench or socket; do not attempt to drive the bolt head. Follow applicable structural fastening requirements per local building codes when used in load-bearing connections.
