Key Features & Benefits at a Glance
- Superior holding power in plastic through thread forming technology that creates strong, permanent threads without chips
- Enhanced corrosion resistance with zinc-plated steel construction for extended service life in industrial environments
- Efficient installation with Phillips No. 2 drive that provides reliable torque transfer and reduces cam-out
- Excellent material displacement thanks to the Tri-Lobe shank design that ensures secure fastening in plastic substrates
- Optimal flush mounting with standard flat head profile and 82° countersink angle for clean, professional finishes
- Full-length threading (19 TPI) provides consistent grip along the entire 5/8" length for maximum fastening security
- Environmental compliance meeting RoHS 3 and REACH regulations for safe use in regulated industries
Professional Applications & Engineering Value
These No. 6 TRS tapping screws are specifically engineered for plastic applications where traditional fasteners fail. The thread forming technology eliminates the risk of plastic cracking during installation by displacing material rather than cutting it, while the Tri-Lobe shank design creates three pressure zones that resist vibration loosening. Made from zinc-plated steel, these screws provide reliable performance in electronic enclosures, automotive plastic components, and consumer products. The Phillips drive ensures compatibility with standard industrial tools, and the 0.138" thread diameter with 19 TPI offers optimal thread engagement in various plastic densities from ABS to polycarbonate.
Specification Summary & Compliance
This 5/8" TRS tapping screw features a No. 6 size with 0.138" thread diameter and 19 threads per inch, fully threaded with right-hand direction. The flat head design includes an 82° countersink angle compatible with standard drill bits (1/8" recommended). Manufactured to precise dimensional standards for consistent performance, these screws are RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, ensuring they meet current environmental regulations for industrial fastener applications.
