Monster Overview:
Fix your project right the first time with M1.6-0.67 Flat-Head 6-Lobe PT Alternative Thread-Forming Screws from Monster Bolts. Their 30° trilobular profile cold-flows thermoplastic bosses, forming chip-free, vibration-resistant threads. A bright CR+3 zinc finish followed by a hydrogen-relief bake delivers RoHS-compliant corrosion protection, while case-hardened carbon steel provides production-grade strength for miniature enclosures, consumer electronics, and precision plastic assemblies.
