Key Features & Benefits at a Glance
- Self-tapping design eliminates the need for pre-tapped holes, reducing installation time and labor costs in brass, cast iron, and sheet metal
- 410 stainless steel construction provides excellent corrosion resistance and durability for demanding industrial environments
- UNF fine thread profile ensures superior holding power and vibration resistance compared to coarse threads
- Phillips No. 2 drive offers widespread tool compatibility and efficient torque transfer during installation
- Fully threaded shank maximizes grip length and load distribution across the entire fastener
- RoHS 3 and REACH compliance guarantees environmental safety and regulatory acceptance for global supply chains
- Optimized for No. 17 drill bit (0.173") ensures proper hole sizing and secure thread engagement in specified materials
Professional Applications & Engineering Value
These 10-32 UNF thread cutting screws solve critical fastening challenges in metalworking applications where traditional fasteners fail. The thread cutting design with Type 23/T tapping method creates precise mating threads in brass, cast iron, and sheet metal without causing material stress fractures. The 410 stainless steel composition maintains structural integrity in corrosive environments, while the Phillips pan head provides a low-profile finish that resists snagging. Engineers specify these fully threaded tapping screws for assembly lines requiring rapid installation and reliable performance in automotive, machinery, and electrical enclosure applications where vibration resistance and long-term durability are paramount.
Specification Summary & Compliance
Manufactured to precise UNF (Unified National Fine) thread standards with Class 2A tolerance for consistent fit. The 3/4" length and No. 10 screw size maintain dimensional accuracy across production batches. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring hazardous substance restriction adherence. The right-hand thread direction and blunt tip facilitate proper alignment and thread starting in pre-drilled holes sized with No. 17 drill bits (0.173" diameter).
