FASTEKS® Threaded Inserts

FASTEKS® steel or stainless steel threaded inserts create precise, durable internal threads in workpieces made of light metal alloy and other materials with low shear resistance.


Features and benefits:

  • Simple installation
  • Self tapping - no threading the mounting hole needed

  • Design 1: Threaded Inserts with Cutting Slots
  • Features
cutting slots

Internal thread sizes:

  • M2,5–M20

Material:

  • Case-hardened steel, zinc-plated, blue passivated, conform to RoHS
  • Stainless steel 1.4305
cutting slots
  • Proven standard product can be used for all applications
  • 2 cutting slots, chip forming
  • The first two threads are tapered, the insert works like a tap
  • For materials with low to medium tensile strength (but tends to spring together in hard materials)

  • Design 2: Threaded Inserts with Cutting Holes, Long
  • Features
cutting holes long

Internal thread sizes:

  • M3–M16

Material:

  • Case-hardened steel, zinc-plated, blue passivated, conform to RoHS
  • Stainless steel 1.4305
cutting holes long
  • Further development of design 1 (with cutting slots)
  • For materials with higher tensile strength (does not tend to spring together)
  • The thread is cut via 3 extremely sharp-edged cutting holes
  • The first two threads are conical, the insert works like a tap
  • Chip forming

  • Design 3: Threaded Inserts with Cutting Holes, Short
  • Features
cutting holes short

Internal thread sizes:

  • M3–M16

Material:

  • Case-hardened steel, zinc-plated, blue passivated, conform to RoHS
  • Stainless steel 1.4305

  • Design 4: Threaded Inserts with Chip Reservoir, Long
  • Features
chip reservoir long

Internal thread sizes:

  • M4–M10

Material:

  • Case-hardened steel, zinc-plated, blue passivated, conform to RoHS
  • Stainless steel 1.4305
chip reservoir long
  • Further development of version 2 (with tapped holes)
  • Suitable for all applications requiring a chip-free internal thread (e.g. for electronic assemblies)
  • Chip reservoir ensures a consistently clean internal thread
  • No springing together, suitable for materials with higher tensile strength

  • Design 5: Threaded Inserts with Chip Reservoir, Short
  • Features
