• Environmental compliance assurance meeting RoHS 3 and REACH standards for global manufacturing requirements

Professional Applications & Engineering Value

These TRS Tri-Lobe thread forming screws are specifically engineered to solve critical challenges in plastic assembly applications. The 18-8 stainless steel construction provides exceptional corrosion resistance while maintaining structural integrity in harsh environments. The unique Tri-Lobe shank cross-section displaces plastic material during installation, creating stronger, more reliable threads that resist vibration loosening and material fatigue. Unlike cutting screws that remove material, these thread forming screws compress and reshape the plastic, resulting in zero chips and significantly reduced stress concentrations around the fastener. The external hex drive ensures maximum torque transmission without cam-out, while the blunt tip design prevents damage to delicate plastic components. These features make them ideal for automotive trim, electronic enclosures, and consumer products where reliable plastic-to-plastic or plastic-to-metal fastening is critical.

Specification Summary & Compliance

This No. 6 x 3/8" TRS screw features precision thread forming technology with a Tri-Lobe shank cross-section, delivering consistent performance in plastic applications. The fastener maintains dimensional accuracy with a thread diameter of 0.138" and 19 threads per inch configuration. Manufacturing and material specifications comply with industry standards for thread forming screws in plastic assemblies. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in global markets. Recommended drill preparation requires a No. 32 drill bit (0.116" diameter) for optimal thread formation and holding strength.
