Crossarm

    Crossarm Pins are forged in one piece from alloy steel with large bases to distribute loads without crushing flat wood crossarms. A square wrenching shoulder is provided above the base for rotating the insulator groove into position.

    Long shank pins come complete with a square washer, square nut and concave MF locknut. Short shank pins for steel crossarms are furnished with a square nut and split coil lockwasher.

    Material:

    • Pin: Forged Steel
    • Threads: Nylon Alloy

    Improved corrosion resistant options are available!

    Better: TDG coated items
