Description
Monster Overview:
Fix your project right the first time with Bulk 3/8-16 6-Lobe Pan Head Taptite Alternative Thread-Rolling Screws from Monster Bolts! These screws form their own robust, reusable threads in untapped holes, making them perfect for assemblies in aluminum, mild steel, brass, and many plastics where vibration resistance and speed are critical.
The trilobular body displaces material instead of cutting it, work-hardening the host material and delivering exceptional joint strength while reducing drive torque. Backed by fast U.S. shipping and legendary Monster Bolts support, they’re the smart choice for automotive, appliance, and general-manufacturing applications.
Monster Features:
- Thread-Rolling Efficiency: Eliminates tapping operations, cutting assembly time and tooling costs.
- Vibration Resistance: Interference fit and work-hardened threads resist loosening under dynamic loads.
- Lower Drive Torque: Trilobular profile reduces friction for smoother, faster install.
- Drive: 6-Lobe (Torx-style) pan head allows high torque transfer with minimal cam-out.
- Quality: Monster Bolts supplies only premium fasteners, backed by responsive customer support.
