Polyamide PA66 (Nylon) Slotted Set Screw - ISO 4766

In stock - 45 items available
SKU: PASG304
Regular price $0.06

Position and retain components without a protruding screw head using our PA66 nylon slotted set screws. Also known as nylon grub screws, these fully threaded metric fasteners sit flush with or below the surface of a compatible tapped hole, making them useful for compact assemblies and adjustable mechanisms.

Manufactured from polyamide 66, these plastic set screws combine low weight, toughness, and electrical insulating properties. The flat point provides a bearing surface against the mating component, while the slotted drive allows adjustment with a flat-blade screwdriver.

Following the ISO 4766 dimensional format, these nylon screws suit light-duty positioning and retention in equipment housings, instruments, and electrical assemblies where nonmetallic hardware is preferred.

Key Features

  • Headless design: Fits flush or recessed within compatible threaded holes.
  • Flat point: Applies contact pressure without a sharp, penetrating tip.
  • Slotted drive: Adjusts with a standard flat-blade screwdriver.
  • PA66 nylon material: Offers good rigidity, toughness, and wear resistance.
  • Lightweight and rust-free: Provides a nonmetallic alternative to steel set screws.
  • Electrical insulation: Supports assemblies requiring nonconductive fasteners.
