  • Diamond-knurled head: Provides a textured grip for hand tightening and loosening.
  • Shouldered design: Offers a bearing surface at the screw head.
  • #4-40 thread: Supports compatibility with matching #4-40 threaded components.
  • Five-screw package: Supplies multiple fasteners for replacement or project needs.

Choose this shoulder thumb screw when a #4-40, hand-operated fastener with a 1/4 in. thread length and 3/8 in. knurled head is the right fit for your assembly.
