    Product Details

    • Manufacturer: Professor Motor
    • Part Number: PMTR7017
    • Thread: #4-40
    • Length: 5/64 in / 2mm
    • Hex Drive: 0.050 in / 1.27mm
    • Material: Heat-treated alloy steel with black oxide finish
    • Quantity: 10

    The hex is broached through the hollow setscrew, so a 0.050-inch Allen wrench can engage from either end. The reduced mass also helps minimize rotating imbalance compared with conventional solid setscrews.
