Monster Overview:
Tame your plastic assemblies with Bulk M3.5-1.57 Torx®/6-Lobe Pan Head PT Alternative Thread-Forming Screws from Monster Bolts! Their 30° PT flank displaces material to form strong, re-tightenable internal threads— no pre-tapping, no chips, and no stripped bosses. A zinc plate & bake finish relieves hydrogen embrittlement and supplies a bright, RoHS-compliant corrosion barrier.
