MonsterBolts Bulk #12-24 Hex-Washer Type F Thread-Cutting Screws — 18-8 Stainless

Monster Overview:

Built for outdoor steel framing, marine docks and heavy trailer decks, these #12-24 Unslotted Indent Hex-Washer Head Thread-Cutting Screws are machined from corrosion-proof 18-8 (304) stainless steel. The captive washer flange spreads load, while the Type F fluted point taps mating threads in a pre-drilled or punched hole—no nut required; chips clear through the flute. Passivated stainless plus a factory dry-wax film deliver low, repeatable drive torque and decades of rust-free performance. Supplied in bulk master cartons to keep your per-piece cost monster-low.

Monster Features:

  • Head / Drive: One-piece unslotted indent hex-washer (5/16″ AF) — smooth top forge, nothing to clog with swarf.
  • Type F Cutting Point: UNC machine thread with fluted slot — perfect for 0.060–0.200″ steel plate or dense hardwood planks.
  • Material Advantage: 18-8 stainless is food-safe, non-magnetic and resists coastal or chemical corrosion.
  • Finish: Passivated + factory dry-wax lubricant (silicone-free) for consistent clamp load.
  • Bulk Packaging: Sealed master cartons — ideal for dock builders, stainless fabrication shops & trailer manufacturers.

Monster Specifications:

  • Diameter / Thread: #12-24 UNC, Type F cutting point
  • Head Style: Unslotted indent hex-washer (integral flange)
  • Drive Size: 5/16″ hex
  • Material: 18-8 (304) stainless steel — passivated
  • Finish: Factory-applied dry-wax
  • Cross-Reference: SAE J476 Type F / IFI 136
