Yokelink Carriage Bolts (also known as Round Head Square Neck Bolts) are universally used in pole line construction to securely attach crossarm braces to wooden crossarms.
The square neck under the smooth, round head is designed to bite into the timber. This self-locking feature prevents the bolt from turning when the nut is being tightened, allowing for fast, one-wrench installation by a single lineman. Manufactured from high-strength carbon steel and fully Hot Dip Galvanized (ASTM A153 Class C) to withstand severe weather conditions.

Head Style: Smooth round head prevents snagging.
Square Neck: Bites into wood crossarms to prevent rotation during assembly.
Application: The industry standard for mounting flat crossarm braces.
Finish: Premium HDG for extended service life in all environments.
Assembly: Includes one hex nut or square nut (as specified).
Dimenisons : Accordance with ANSI/ASME B18.5
