- Optimized pan head design provides excellent bearing surface for consistent clamping force in plastic assemblies
- Full threading along 5/8" length delivers maximum holding power and uniform stress distribution
- Precision No. 10-16 thread pitch ensures perfect engagement with plastic components for vibration resistance
- Environmental compliance meets RoHS 3 and REACH standards for safe use in regulated industries
Professional Applications & Engineering Value
These 410 stainless steel tapping screws are specifically engineered for plastic fastening applications where material integrity and long-term performance are critical. The thread forming technology (DST type) displaces plastic material rather than cutting it, creating stronger threads that resist stripping and loosening under vibration. The Phillips pan head design with standard rounded profile ensures consistent seating without damaging plastic surfaces, while the fully threaded shank provides maximum engagement depth. Ideal for industrial assembly of plastic enclosures, components, and structural elements, these screws eliminate the need for inserts while maintaining superior pull-out strength in various plastic substrates.
Specification Summary & Compliance
This No. 10-16 thread tapping screw features precision Class 2A thread tolerances with right-hand threading and 16 threads per inch. The DST thread forming type requires No. 21 drill bit (0.159" diameter) for proper installation in plastic materials. Manufactured to industry standards for tapping screw applications, these fasteners are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in electronic, automotive, and consumer product assemblies.
