Plasti-Kwick II screws feature a double lead form and a unique high and low thread configuration.

The high sharper 300 included angle thread provides more thread engagement and produces a wider margin between drive to strip ratios while the 600 included angle low thread stabilizes driving. This high and low thread combination yields low drive, in installation, and superior pull out results.

• Intended for fastening in plastics with medium to high stiffness 
• Imparts less internal stress - less tendency to fracture bosses
