Description
Monster Overview:
Fix your project right the first time with Bulk 5/16"-18 Flat Head 6-Lobe / T-40 Thread Cutting Screws (Type F) from Monster Bolts. These screws are commonly used in floorboard and heavy-duty structural applications, where a flush finish and high drive torque are required.
The Type F thread cutting design cuts clean internal threads rather than rolling them, making these fasteners ideal for steel and harder materials. The flat head design allows the screw to sit flush, while the 6-lobe (Torx®-style) T-40 drive provides excellent torque transfer with reduced cam-out. A phosphate finish offers added lubricity and is commonly used in industrial and automotive environments.
