Taptite 2000® Fasteners

Elco AllFlex
Elco AllFlex Fasteners

High performance thread rolling screws specially designed to lower your in-place fastening costs.

Taptite 2000® screws form internal threads into plain holes in ductile materials upon initial installation, which:

  • Eliminates the need to pre-tap the nut member
  • Reduces problems associated with assembling screws and bolts into pre-tapped holes, such as cross-threading

    • Reduces friction
    • Increases prevailing torque
    • Resists loosening caused by vibration
    • Lower end load requirements
    • Lowers thread forming torque without sacrificing performance
    • Higher, more uniform drive-to-fail ratio
    • Increased drive-to-strip ratio
    • Resist internal thread stripping
    • Excellent axial alignment
    • Results in higher strength internal threads due to the cold flow/work hardening that occurs during the forming of the nut thread
    • Significantly extends tool life
    • Ideal drive system for maximum torque transfer
