Description
Monster Overview:
Fix your project right the first time with Bulk 5/16-18 6-Lobe Flat Head Taptite Alternative Thread-Rolling Screws from Monster Bolts! These trilobular fasteners roll-form tough, reusable threads in untapped holes—cutting assembly time while resisting vibration in aluminum, mild steel, brass, and plastics.
The flush-sitting 82° countersunk head uses a hexalobular / Torx® star-drive (6-lobe) recess for maximum torque transfer. A bright zinc bake & wax finish adds lubricity and RoHS-compliant corrosion protection. Perfect for automotive panels, appliances, and general-manufacturing builds where a clean, flat surface is required.
Monster Features:
- Thread-Rolling Efficiency: Eliminates tapping operations, saving tooling costs and cycle time.
- Vibration Resistance: Interference fit and work-hardened threads resist loosening under dynamic loads.
- Flush Finish: 82° flat (countersunk) head sits level with the surface for a smooth appearance.
- Drive: Hexalobular / Torx® star 6-lobe recess delivers high torque with minimal cam-out.
- Quality: Monster Bolts supplies only premium fasteners, backed by responsive customer support.
