1/4-20 x 2 Carriage Blt HDG

Overview

The 1/4-20 x 2 Carriage Bolt HDG (05477) is designed for hardware fastening applications requiring a secure, non-rotating bolt connection, particularly in wood assemblies.

Technical Specifications

Technical Features

• Hot-Dip Galvanized (HDG) finish: Provides a zinc coating applied through immersion, delivering corrosion resistance suited for outdoor and moisture-exposed installations.
• Domed head profile: Presents a smooth, low-profile bearing surface on the finished face of the assembly, reducing snag and abrasion hazards at the exposed end.
• Square shoulder under head: Bites into the substrate material — typically wood — when the nut is driven, preventing bolt rotation and allowing single-sided tightening without a secondary tool on the bolt head.
• 1/4-20 thread specification: Standardized Unified National Coarse (UNC) thread pitch ensures broad compatibility with stock 1/4-20 nuts, washers, and threaded inserts.
• 2-inch shank length: Accommodates fastening through common dimensional lumber thicknesses with thread engagement sufficient for a secure nut seat.

Applications

• Wood deck and fence construction where a flush, snag-free bolt head is required on the exposed face.
• Outdoor lumber connections subject to weather exposure, where the HDG coating provides corrosion protection.
• General wood-to-wood and wood-to-metal assembly where a non-rotating fastener simplifies installation.
• Playground equipment, pergolas, and landscape structures requiring a smooth exterior bolt-head finish.
