Professional Applications & Engineering Value

This No. 10-12 x 1/2" 316 stainless steel flanged hex head tapping screw delivers exceptional engineering value in demanding sheet metal applications where corrosion resistance and vibration tolerance are critical. The thread forming technology creates stronger, more durable connections by displacing material rather than removing it, resulting in superior pull-out strength and resistance to loosening under dynamic loads. The flanged hex head design combines the installation convenience of external hex drive with the load-spreading benefits of an integrated washer, streamlining assembly processes while preventing surface damage. Manufactured from premium 316 stainless steel, this fully threaded screw maintains integrity in corrosive environments including marine, chemical processing, and outdoor applications, making it ideal for HVAC systems, electrical enclosures, and industrial equipment where reliability is paramount.

Specification Summary & Compliance

This No. 10 tapping screw features a 0.19" thread diameter with 12 threads per inch and Class 2A thread tolerance for precise fit. The 1/2" length and fully threaded design provide maximum engagement in materials up to 0.025" thickness. Compatible with No. 21 drill bit (0.159" diameter) for proper hole preparation. Manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across global industrial markets.
