Key Features & Benefits at a Glance
- Superior corrosion resistance with zinc-plated steel construction, extending service life in demanding industrial environments.
- Efficient thread cutting action with Type F tapping design, enabling secure fastening in aluminum, brass, cast iron, and sheet metal without pre-tapping.
- Reliable drive engagement via No. 2 Phillips drive, reducing cam-out risk and improving installation speed.
- Enhanced load distribution with standard pan head profile, minimizing surface damage and providing a flush finish.
- Precision fine thread spacing (UNF) ensures tighter seals and vibration resistance in high-stress assemblies.
- Full threading along 3/8" length maximizes grip strength and pull-out resistance across the entire fastener.
- Compatible with No. 17 drill bit (0.173" diameter) for streamlined hole preparation and reduced assembly time.
Professional Applications & Engineering Value
These 10-32 UNF zinc-plated steel tapping screws deliver exceptional performance in metalworking and fabrication. The thread-cutting F-type design eliminates the need for separate tapping operations, significantly reducing labor costs and assembly errors in materials like aluminum, brass, cast iron, and sheet metal. The fine UNF thread spacing provides superior resistance to loosening under vibration, critical for automotive, machinery, and electrical enclosures. Combined with the corrosion-resistant zinc plating, these screws maintain integrity in humid or outdoor settings, ensuring long-term reliability while meeting strict industry specifications for precision fastening.
Specification Summary & Compliance
Manufactured to ASME B18.6.3/SAE J933 standards, these screws guarantee consistent thread diameter (0.19") and Class 2A tolerance for reliable fit. Fully compliant with RoHS 3 (2015/863/EU) regulations, ensuring safe use in electronic and consumer goods. The UNF fine thread system and blunt tip facilitate precise alignment and reduce cross-threading risks in pre-drilled holes sized for No. 17 drill bits.
