Key Features & Benefits at a Glance
- Superior plastic retention with tri-lobe shank design that displaces material to create durable, vibration-resistant threads without pre-drilled tapping.
- Enhanced corrosion resistance through zinc-plated steel construction, ensuring longevity in industrial environments.
- Efficient installation with Phillips No. 1 drive for secure tool engagement and reduced cam-out during high-torque applications.
- Maximum holding power from fully threaded design, distributing load evenly across the entire 3/8" length for reliable plastic assembly.
- Optimized thread engagement with 28 threads per inch and blunt tip for controlled penetration in plastic substrates.
- Regulatory compliance assurance meeting RoHS 3 and REACH standards for safe use in global manufacturing applications.
Professional Applications & Engineering Value
These No. 2 zinc-plated steel TRS tapping screws deliver exceptional performance in plastic fastening applications where traditional fasteners fail. The thread forming action of the tri-lobe shank compresses plastic material rather than cutting it, eliminating chips and creating stronger thread engagement that resists loosening under vibration. The Phillips drive provides reliable torque transfer during installation in automated assembly lines, while the zinc plating protects against environmental corrosion in industrial settings. Engineered specifically for plastic substrates with recommended No. 47 drill bit preparation, these screws solve common challenges of strip-out, material cracking, and inconsistent clamp force in plastic components across automotive, electronics, and consumer goods manufacturing.
Specification Summary & Compliance
Manufactured to precise dimensional standards with 0.086" thread diameter, 28 TPI thread pitch, and 3/8" length tolerance. Features right-hand threading, standard pan head profile with 0.167" diameter, and blunt tip configuration. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations for hazardous substance restrictions, ensuring environmental responsibility and global market acceptance.
