Key Features & Benefits at a Glance
- Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh industrial environments and long-term reliability.
- Efficient thread forming design creates strong, permanent threads in sheet metal without pre-tapping, reducing installation time and labor costs.
- High-torque square drive (No. 3) prevents cam-out for secure fastening and reduced tool wear during high-volume assembly.
- Fully threaded shank ensures maximum grip and uniform load distribution across the entire fastened material thickness.
- Optimized for 0.025" maximum drilling thickness with precise 5.5mm drill bit compatibility, preventing material deformation in thin sheet metal applications.
- Pan head design provides a low-profile, finished appearance while offering a larger bearing surface for secure fastening.
- Environmental compliance meets RoHS 3 and REACH standards, ensuring safe use in regulated industries and global markets.
Professional Applications & Engineering Value
These No. 14 x 1/2" sheet metal tapping screws deliver exceptional performance in thread forming applications where material integrity is critical. The 18-8 stainless steel composition resists oxidation and chemical exposure, making these Type A/AB screws ideal for HVAC systems, electronic enclosures, and automotive assemblies. The fully threaded design and pointed tip enable quick starts and consistent thread engagement in materials up to 0.025" thick, eliminating the need for separate tapping operations. This thread forming screw solution reduces assembly steps while maintaining vibration resistance and pull-out strength in demanding sheet metal fastening scenarios.
Specification Summary & Compliance
These screws feature a 0.242" thread diameter with 10 threads per inch and Class 2A thread tolerances for consistent fit. Manufactured to Type A/AB thread forming standards with a 1/2" length and square drive (No. 3) configuration. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for industrial use.
