Professional Applications & Engineering Value

These TRS thread forming screws are specifically engineered to address common challenges in plastic assembly applications where material integrity is critical. The Tri-Lobe shank cross-section displaces plastic material during installation rather than cutting it, creating zero clearance threads that eliminate the risk of stress cracking common with traditional thread-cutting screws. This thread forming technology combined with the blunt tip design ensures controlled entry and prevents damage to delicate plastic components. The black zinc-plated steel construction provides essential corrosion protection while maintaining the mechanical strength required for durable fastening in plastic materials. With 20 threads per inch and precise 0.112" thread diameter, these screws deliver consistent performance across various plastic types from thermoplastics to reinforced composites.

Specification Summary & Compliance
