MonsterBolts Bulk #12-24 Phillips Flat-Undercut Thread-Cutting Screws — Black Oxide

Monster Overview:

Need a perfectly flush countersink in thin sheet-metal or shallow recesses? Our #12-24 Phillips Flat-Undercut Thread-Cutting Screws shave away most of the 82 ° cone, delivering maximum thread engagement without head protrusion. Heat-treated carbon steel wears a durable black-oxide conversion coat, sealed with oil and factory dry-wax for low, consistent drive torque. A Type F fluted point taps clean internal threads in a pre-drilled or punched hole; chips clear through the flute—no nut required.

Monster Features:

  • Undercut Head: Shallow 82 ° design keeps heads flush in sheet as thin as 0.050″ while preserving full thread length.
  • Flush Seating & Drive: Phillips #3 recess—high torque with minimal cam-out.
  • Type F Cutting Point: UNC machine thread with fluted slot—forms threads in 0.060–0.200″ steel plate or dense hardwood; chips exit cleanly.
  • Finish: Black-oxide (oil-sealed) plus factory dry-wax for smooth installation and indoor corrosion resistance.
  • Material: Heat-treated carbon steel delivers excellent tensile and shear strength.
  • Bulk Packaging: Sealed master cartons—ideal for HVAC skins, appliance frames & OEM fabrication where thin sheet meets flush fit.
