MonsterBolts Bulk 3/8-16 Torx Flat Type F Floor-Board Screws — Black Phosphate

Monster Overview:

Built for truck beds, heavy trailer floors, structural steel decking and laminated timbers, these 3/8″-16 6-Lobe (Torx) Flat Head Floor-Board Screws incorporate a Type F fluted cutting point that taps its own internal threads in mild steel or dense hardwood— eliminating nuts, pre-tapping and chip cleanup. A low-glare black-phosphate conversion coat meets RoHS requirements and partners with a factory wax/oil film for predictably low drive torque. Supplied in bulk master cartons to drive per-piece cost down.

Monster Features:

  • Type F Cutting Point: Machine-screw thread with fluted slot—ideal for 0.090-0.250″ steel plate or hardwood planks.
  • Drive: Torx® T45 6-lobe recess—high torque transfer with virtually zero cam-out.
  • Floor-Board Flat Head: 82° countersunk profile seats flush; under-head nibs bite for a clean, level set-down.
  • Finish: Black-phosphate + light oil (RoHS) with factory dry-wax for consistent clamp load.
  • Bulk Packaging: Sealed master cartons—perfect for OEM fabricators, trailer manufacture and fleet maintenance.

Monster Specifications:

  • Diameter / Thread: 3/8″-16 UNC, Type F cutting point
  • Head Style: Flat countersunk 82° with floor-board nibs
  • Drive Size: Torx T45
  • Material: Heat-treated carbon steel
  • Finish: Black phosphate + oil/wax (RoHS compliant)
