The Allied Bolt Galvanized Lag Screw (vendor part 762, Millennium part 585056) is a 1/4 in x 3 in screw with a 7/16 in hex head for fastening pole line hardware to telephone poles and wood structures. Grade 2 steel with a B70-B100 Rockwell hardness rating and hot-dip galvanizing to ASTM A153 gives it the strength and corrosion resistance needed for long-term outdoor pole hardware attachment. Crews use it for lighter-duty mounting where the larger 3/8 in and 5/8 in lag screws would be oversized. Millennium stocks the full lag screw range alongside washers and straps for complete hardware installs.
