Thread Rolling Screws/ Thread Forming Screws

Thread rolling screws are designed for reliable and secure fastening into materials such as plastic. They have a  trilobular lobed cross-section, and form threads in pre-existing holes by pushing material outward during installation. When installed in sheet metal, thread rolling screws often require an extruded hole; the extrusion forms a lead-in and provides extra length for improved retention. Thread rolling screws are popular for applications where the loose chips formed by thread cutting processes must be avoided.

Value Fastener maintains a huge, in-stock inventory of steel thread forming screws and stainless steel thread forming screws. We carry a variety of brands and styles, including Plas-Fix® 45 and Plastite® and EJOT® PT® metric thread rolling screws, and Taptite® and Plastite® inch-size thread rolling screws.

EJOT® PT®-Alternative,  Metric Thread Rolling Screws

With a high thread profile and recessed thread root, the PT® screw provides increased thread engagement with minimal stress on the boss. It provides optimal performance in a wide range of thermoplastics.
  • Narrow 30° thread profile
  • Optimum thread pitch
  • Round body
  • Recessed thread root
  • Provides maximum resistance to back-out and pull-out
  • Minimizes boss failure

Plas-Fix®45 and Plastite®-Alternate,Metric Thread Rolling Screws and Plastite®-Alternative, Inch Sizes Thread Rolling Screws

The PLASTITE® 45 screw is designed to facilitate thread-forming in less-compressible plastics while providing high resistance to strip-out and pull-out.
It has smaller root and major diameters than a 48° PLASTITE®, so it can be used in smaller bosses.
  • Tri-roundular configuration that allows displaced material to cold flow back into relief areas.
  • 45° profile allows thread to penetrate deeply into plastic material
  • Single lead design and narrow helix angle lowers drive torque and failure torque in stiffer plastics
  • Reduces possibility of boss failure
  • Increases product reliability
  • Eliminates need for inserts and lock washers
  • Minimizes radial stress
  • Allows design of thinner bosses
  • Generates strong mating threads
  • Resists vibration loosening
  • Reduces probability of strip-out and pull-out
  • Achieves wide differentials between drive and fail torque
  • Creates less stress on the boss

Taptite®-Alternative, Inch Sizes Thread Rolling Screws

TAPTITE 2000® fasteners are 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
  • Trilobular™ configuration
  • Radius Profile Thread™
  • Roll forms own work-hardened mating threads
  • Available with TORX Plus® Drive System
  • 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
  • Formed thread can accept metric fastener
Design Guidelines
  • Drive Systems: All styles available; TORX Plus® Drive System recommended
  • Point Style: Standard TAPTITE® point; also available in SP™ (short point) and CA point
  • Materials: Low carbon steel, medium carbon steel, alloy steel, stainless steel
  • Finishes: Will accept all typical finishes
