Key Features & Benefits at a Glance
- Superior corrosion resistance with zinc-plated steel construction, ensuring long-lasting performance in industrial environments.
- Efficient thread forming design creates strong, permanent threads in plastic materials without pre-tapping, reducing assembly steps.
- Optimized for plastic applications with blunt tip and fully threaded shank to prevent material cracking and ensure secure fastening.
- Reliable drive engagement with Phillips No. 3 drive style, providing consistent torque transfer and reducing cam-out risks.
- Standardized dimensions including 0.242" thread diameter and 15 TPI, ensuring compatibility with No. 7 drill bits (0.201") for precise installations.
- Enhanced head design with rounded pan profile offering a low-profile finish and improved clamping force distribution.
- Industry compliance meeting ASME B18.6.3 specifications, guaranteeing consistent quality and interchangeability.
Professional Applications & Engineering Value
These No. 14 x 1" zinc-plated steel tapping screws are engineered to address common challenges in plastic assembly, such as material stress and thread stripping. The thread forming technology (DST type) displaces plastic material to create robust, load-bearing threads without generating chips, minimizing the risk of weak points. The fully threaded design and blunt tip ensure even stress distribution, preventing cracks in brittle plastics. With a Phillips drive and rounded pan head, they provide reliable fastening in automotive trim, electronic enclosures, and consumer products, enhancing assembly speed and joint integrity in high-volume production.
Specification Summary & Compliance
This product adheres to ASME B18.6.3 standards, ensuring precise thread dimensions (0.242" diameter, 15 TPI) and consistent performance. The zinc-plated steel material offers durability, while the thread forming method and right-hand threading provide reliable fastening in plastic substrates. Designed for use with a No. 7 drill bit (0.201" diameter), it meets industry requirements for dimensional accuracy and is suitable for applications requiring compliance with general industrial specifications.
