Description
Monster Overview:
Built for thermoplastic lids and miniature housings, these #4-20 Phillips Flat Head PT 48-2 Thread-Forming Screws use a Plastite-alternative tri-lobular flank that cold-flows plastic, cutting chip-free internal threads—no pre-tapping, no debris.
Each heat-treated carbon-steel screw receives a deep black-oxide conversion coat for low-glare corrosion protection, followed by a factory wax film for consistently low seating torque. Bulk master cartons keep your per-unit cost razor-low.

- Plastite-Alt. PT 48-2 Geometry: Maximises pull-out resistance while fighting strip-out in ABS, nylon, PC & more.
- Drive: Phillips #1 cross recess—reliable with manual, pneumatic, or automated drivers.
