Professional Applications & Engineering Value

These No. 5 x 3/4" zinc-plated steel TRS tapping screws are specifically engineered for plastic assembly applications where reliable, vibration-resistant fastening is critical. The thread forming technology creates strong, permanent threads in plastic materials without generating chips, eliminating contamination risks in sensitive assemblies. The Tri-Lobe shank design provides superior resistance to loosening under vibration and thermal cycling, making these Phillips drive screws ideal for automotive trim, electronic enclosures, and consumer products. The zinc-plated steel construction ensures durability while the fully threaded design with 20 TPI offers consistent holding power throughout the fastener length, preventing pull-out in brittle plastics.

Specification Summary & Compliance

These thread forming screws feature a 0.125" thread diameter with 20 threads per inch and Tri-Lobe shank cross-section, designed for use with No. 33 drill bits (0.113" diameter). Manufactured to industry standards for tapping screws with right-hand threading and blunt tip configuration. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory adherence for industrial applications worldwide.
