- Environmental compliance with RoHS 3 and REACH standards ensures safe, sustainable use in regulated industries.
Professional Applications & Engineering Value
These No. 10 x 3-1/2" stainless steel oval head tapping screws are engineered specifically for sheet metal fastening where reliability and corrosion resistance are critical. The thread forming (Type A/AB) technology displaces material to create strong, vibration-resistant threads without chips, eliminating debris in sensitive assemblies. Made from 18-8 stainless steel, they withstand moisture, chemicals, and outdoor exposure, reducing maintenance in HVAC, electrical enclosures, and industrial machinery. The Phillips drive and fully threaded design ensure quick installation and consistent clamping force, making them ideal for high-volume manufacturing and maintenance operations requiring durable, compliant fasteners.
Specification Summary & Compliance
This screw features a No. 10 size with 0.19" thread diameter and 12 threads per inch, following standard inch measurements. The oval head design conforms to typical profiles with specified head diameter and height. Manufacturing adheres to common thread forming (Type A/AB) specifications for sheet metal. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring no restricted substances are used.
