Advantages<\/h2>\n
\n
\n
\n \"Anti-Rotation\n <\/div>\n

Anti-Rotation Locking<\/h3>\n

The unique pig-tail curved hook mechanically embeds into the wood pole substrate, creating a form-locking anchor that prevents bolt rotation and eliminates pull-out under sustained tension loads. The square plate washer distributes force over a large bearing area.<\/p>\n <\/article>\n

\n
\n \"Forged\n <\/div>\n

Forged Steel Strength<\/h3>\n

Forged from premium carbon steel for maximum density and grain refinement, the pig bolt body achieves exceptional tensile and shear strength at the critical hook-to-shank transition zone.<\/p>\n <\/article>\n

\n
\n \"Corrosion\n <\/div>\n

Corrosion Resistance<\/h3>\n

Hot-dip galvanizing provides a thick, durable zinc coating that withstands the chemically aggressive environment of treated wood poles, maintaining integrity in direct ground contact and high-moisture decay zones.<\/p>\n <\/article>\n

\n
\n \"Field-Ready\n <\/div>\n

Field-Ready Assembly<\/h3>\n

Each pig bolt is supplied as a complete kit with square plate washer and double nuts for jam-locking security, enabling rapid and reliable field installation with basic hand tools.<\/p>\n <\/article>\n <\/div>\n \n
