- Efficient thread forming design (Type A/AB) creates strong, permanent threads in sheet metal without pre-tapping.
- Flush, professional finish with standard oval head and 82° countersink angle for seamless surface integration.
- Secure installation and reduced cam-out using Phillips No. 3 drive for reliable torque transfer.
- Full threading along the 1-1/4" length ensures maximum grip and uniform load distribution in materials.
- Precise compatibility with 5.5 mm (0.2165") drill bits for accurate hole preparation in sheet metal up to 0.025" thickness.
- Compliance with global safety standards including RoHS 3 and REACH for environmentally responsible sourcing.
Professional Applications & Engineering Value
These No. 14 oval head tapping screws are engineered to address common challenges in sheet metal assembly, such as material fatigue and corrosion. The 18-8 stainless steel offers excellent durability against rust and chemicals, while the thread forming (Type A/AB) design eliminates the need for separate tapping operations, reducing installation time and tooling costs. The fully threaded shank and pointed tip facilitate easy starts and consistent engagement, preventing stripping in thin-gauge metals. With a Phillips drive and precise 82° countersink, these screws provide a secure, flush fit that maintains structural integrity in HVAC, electronics enclosures, and automotive panels, ensuring long-term performance even under vibration and thermal stress.
Specification Summary & Compliance
This product adheres to standard inch measurements with a thread diameter of 0.242" and approximately 10 threads per inch, ensuring precise fit in sheet metal applications. It meets common industry specifications for thread forming tapping screws (Type A/AB) and features a right-hand thread direction for universal use. Compliance is confirmed with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, supporting safe and sustainable manufacturing practices without hazardous substances.
