Top Pick Bulk 1/2″-13 Unslotted Indent Hex-washer Serrated Head Thread-cutting Screws — Type F, Bright-zinc & Hydrogen-relief Baked Accessory [GmdK5Lqu]

Monster Overview:

Engineered for truck beds, heavy trailer decks, dock framing and structural steel, these 1/2″-13 Unslotted Indent Hex-Washer Serrated Thread-Cutting Screws deliver maximum clamp load that stays put. Heat-treated carbon-steel blanks receive a high-luster bright-zinc electro-plate, are hydrogen-relief baked, then factory dry-waxed for consistently low seating torque. The integral washer’s radial serrations bite into steel or wood, resisting loosening from vibration, while the Type F fluted point taps clean female threads in a pre-drilled or punched hole—chips clear through the flute; no nut required.

Monster Features:

• Serrated Bearing Face: 360° teeth dig into the mating surface for exceptional resistance to loosening under shock and vibration.
• Head / Drive: Unslotted indent hex-washer (¾″ AF) — smooth top forge won’t trap swarf; captive serrated washer spreads load.
• Type F Cutting Point: UNC machine thread with fluted slot — forms internal threads in 0.100-0.250″ steel plate or dense hardwood.
• Finish: Bright-zinc (RoHS) + light oil, hydrogen-relief baked, topped with factory dry-wax for repeatable clamp load.
• Material: Heat-treated carbon steel for high tensile and shear strength.
• Bulk Packaging: Sealed master cartons—ideal for trailer builders, dock constructors & OEM steel fabrication lines.
