Not your ordinary screw. The ESCO Blade Lock Screw has both right hand and left hand threads for unmatched holding power.
To compliment the ESCO Blade Lock and increase its holding force, we mate the Blade Lock with the double threaded ESCO Blade Lock Screw. The stretching force this screw produces is double that of a single threaded screw and doubles the holding force of the Blade Lock on the Cutter Blade clamping surface.
