• Clean, finished appearance with an oval head that sits flush in 82° countersunk holes for a professional look.
• Optimized for sheet metal with a pointed tip and fully threaded design for maximum grip in materials up to 0.025" thick.
• Wide compatibility with a No. 21 drill bit (0.159" diameter), ensuring precise hole preparation and secure fastening.
• Compliance assurance meeting RoHS 3 and REACH regulations for safe, environmentally responsible use in global markets.

Professional Applications & Engineering Value

These No. 10 x 1" Phillips Oval Head Thread Forming Tapping Screws are engineered to solve common fastening challenges in sheet metal assemblies. The Black-Oxide Steel construction provides a durable, corrosion-resistant finish ideal for HVAC, electronics enclosures, and automotive panels. The thread forming design displaces material to create robust internal threads without chips, eliminating debris in sensitive applications. With a fully threaded shank and 12 threads per inch, these A/AB type tapping screws deliver consistent clamping force and vibration resistance, reducing maintenance needs and improving assembly reliability in high-stress environments.

Specification Summary & Compliance

This screw features a 0.19" thread diameter with Class 2A inch-series tolerances and standard right-hand threading. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety. The 82° countersink angle and oval head profile meet industry standards for flush mounting in sheet metal applications up to 0.025" maximum drilling thickness.
