Metal Core


PROTECTINSULATEISOLATE

The Shear Strength of heat-treated steel.
The Dielectric insulation, corrosion resistance, and vibration resistance of nylon.

A perfect combination to replace:

  • Costly Brass and Stainless Steel Fasteners
  • Costly Multiple Component Insulated Screw Assemblies
  • Costly Sleeved and Cladded Screws
  • Marginal Standard Nylon Fastener Applications

Metal Core Screws are recommended in applications requiring electrical, thermal, and vibration insulation in shear or double shear connections.

These reinforced screws will provide up to 4 times the strength of standard nylon fasteners.

High Dielectric ResistancePrecision Cold Formed and Knurled
Corrosion ResistantElectro Zinc or Cadmium Plated
Vibration and Abrasion Resistant

The reinforcing core incorporates a recessed metal head that permits tightening with high speed, high torque automatic drives.

Due to the corrosion resistant nature of the nylon, the metal core screws can, in certain applications, replace expensive stainless steel, brass, and Monel fasteners at a substantial cost savings.

The insulating quality of the nylon shell makes the metal core screws an ideal choice for areas where cathodic or thermal transfer is a problem.
