The B Cable Suspension Screw attaches messenger suspension clamps and cable hangers to utility poles where thru-bolts cannot be used, particularly when maintaining proper clearance from other vertical runs on jointly used poles.
The screw features an integral forged washer-nut connecting the lag screw end to the machine screw stud end. The lag screw includes a gimlet point with sharp rolled threads, while the stud end has a forged square washer head and roll threaded stud assembled with a square nut for secure attachment in light-duty mounting applications.
Made from high-quality steel, the screw receives hot-dip galvanizing per American Society for Testing and Materials (ASTM) A-153 or ASTM F2329 specifications, providing corrosion resistance for outdoor utility environments.
The lag screw measures 7/8 inch diameter by 5-1/2 inches length, paired with a 5/8 inch diameter machine screw stud ranging from 1-1/2 to 2-1/4 inches length. Installation requires a 3/4-inch pilot hole for driving into wooden poles.
