AFT Advanced Anti-Backlash Supernuts

Thomson BSA's cost effective AFT Advanced Anti-Backlash nut offers excellent performance up to 10 lbs.  Accompanies sizes of acme screw from 3/8 inch diameter though to 7/16 inch with metric versions also available. Ideal for OEM applications, this nut effectively removes backlash and maintains low drag torque and smooth movement.  The anti-backlash mechanism adjusts as normal wear occurs between screw and nut.  Integral tri-flange provides an easy attachment to application.
