S-90197A247 Length 1" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, extending service life in demanding industrial environments
• Enhanced holding power through thread forming technology that creates stronger, vibration-resistant connections in sheet metal
• Simplified installation with combined external hex/slotted drive options for flexible tool compatibility and faster assembly
• Efficient material penetration thanks to the pointed needle tip design that reduces installation force and prevents material splitting
• Increased bearing surface from the integrated flange design, distributing load evenly and preventing pull-through in thin materials
• Maximum thread engagement with fully threaded shank design ensuring consistent holding strength along the entire fastener length
• Precision compatibility with No. 21 drill bit (0.159" diameter) for optimal thread formation and secure fastening in sheet metal up to 0.05" thickness

Professional Applications & Engineering Value

This No. 10-12 zinc-plated steel flanged tapping screw delivers exceptional performance in sheet metal applications where vibration resistance and pull-out strength are critical. The thread forming technology eliminates the need for pre-tapped holes while creating stronger, more durable threads that won't strip under stress. The combination of external hex/slotted drive provides installation flexibility for both power and manual tools, speeding up assembly processes in manufacturing, HVAC, and electrical enclosure applications. The flanged design acts as an integrated washer, distributing clamping force across a wider area to prevent material deformation in thin-gauge metals. With its fully threaded construction and needle point tip, this fastener reduces installation torque requirements while ensuring maximum thread engagement for superior holding power in challenging industrial environments.

Specification Summary & Compliance

This No. 10-12 x 1" flanged tapping screw features precision right-hand threads with 12 TPI and 0.19" thread diameter, manufactured to industry standards for reliable performance. The fastener is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and workplace safety. Designed specifically for use with No. 21 drill bits (0.159" diameter), this screw provides optimal performance in sheet metal applications up to 0.05" maximum drilling thickness, delivering consistent results across production runs.
