Key Features & Benefits at a Glance
- Enhanced corrosion resistance with zinc-plated steel construction for reliable performance in demanding environments
- Superior torque transmission and reduced cam-out with Torx Plus IP7 drive for efficient, secure installations
- Excellent thread-forming capability in plastics thanks to the Tri-Lobe shank design that displaces material without creating chips
- Full 1/4" threading with 28 TPI provides maximum holding power and vibration resistance in plastic assemblies
- Simplified installation process with precise 5/64" drill bit compatibility for accurate pilot hole preparation
- Broad industrial compliance meeting RoHS 3 and REACH regulations for safe, sustainable manufacturing
- Blunt tip design prevents damage to delicate plastic components during assembly
Professional Applications & Engineering Value
These No. 2 zinc-plated steel tapping screws are specifically engineered for plastic applications where traditional fasteners often fail. The TRS thread forming technology with Tri-Lobe shank cross-section creates strong, permanent threads in plastic substrates without generating debris that could compromise electronic components or moving parts. The Torx Plus IP7 drive system delivers superior torque transfer, eliminating stripping and cam-out issues common in high-volume assembly operations. Ideal for industrial plastic fastening in automotive trim, electronic enclosures, and consumer products, these screws provide reliable thread forming performance while the zinc-plated steel construction ensures durability against environmental exposure.
Specification Summary & Compliance
These tapping screws feature precise No. 2 screw size with 1/4" length and 28 TPI fully threaded design. The TRS thread forming screws maintain consistent dimensional accuracy with right-hand threading and blunt tip configuration. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and industrial safety standards. The Torx Plus IP7 (T7) drive system provides standardized compatibility with industry tooling for consistent installation performance.
