3/8" Square Head Machine Bolt Hot Dip Galvanized IEEE C135.1 & CSA C83 Rolled Thread

The Yokelink 3/8" Square Head Machine Bolt series is designed for lighter duty utility applications, specifically for securing crossarm braces, secondary racks, and other pole line attachments. Despite their smaller size, these bolts are manufactured with the same rigorous quality control as our heavy-duty hardware, meeting IEEE Std C135.1 specifications.

Square Head Bolt Key Features & Benefits:

Rolled Threads: Produced by thread rolling process to provide greater tensile strength and fatigue resistance compared to cut threads.
Chamfered Point: Features a chamfered or sheared end for easy starting of the nut, adhering to standard specifications for 3/8" diameter bolts.
Corrosion Resistance: Hot Dip Galvanized to ASTM A153 Class C, ensuring long-term protection in coastal and industrial environments.
Ready to Install: Supplied with a square nut assembled.

Engineered for Cold Climates (CSA C83 Compliant):

Winter Ready: Ideal for the Canadian market. Our steel formulation maintains integrity in low temperatures (-20°C).

Oversize Tapping: Nuts are tapped oversize to ensure they spin freely even when installing with gloved hands in freezing conditions.

Technical Specifications (3/8" Diameter):

Min. Tensile Strength: 4,250 lbs (18.9 kN)
Thread Standard: UNC 2A
