Professional Applications & Engineering Value

These No. 5 x 3/8" zinc-plated steel tapping screws are specifically engineered for plastic assembly applications where material integrity and fastening reliability are critical. The thread forming TRS technology creates strong, permanent threads in plastic substrates without generating chips or stress fractures that compromise structural integrity. The tri-lobe shank design provides exceptional resistance to vibration loosening, making these T10 Torx drive screws ideal for automotive components, electronics enclosures, and consumer products where plastic-to-plastic or plastic-to-metal connections require durable, maintenance-free fastening solutions. The combination of 20 threads per inch and fully threaded design ensures maximum engagement strength while the zinc-plated steel construction offers reliable corrosion protection for extended service life in demanding industrial environments.

Specification Summary & Compliance

These thread forming tapping screws feature precise No. 5 thread diameter (0.125") with 20 threads per inch and 3/8" length for standardized plastic fastening applications. The tri-lobe shank cross-section and thread forming tapping method ensure secure installation without pre-tapping requirements. Manufactured to industry standards for plastic fasteners with right-hand threading and standard pan head profile. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for industrial safety and global market acceptance.
