Key Features & Benefits at a Glance
- Superior corrosion resistance with zinc-plated steel construction, ensuring long-lasting performance in industrial environments.
- Enhanced driving efficiency provided by the 3/8" external hex head, allowing for secure installation with standard tools.
- Reliable thread formation in sheet metal without pre-tapping, reducing assembly time and tooling costs.
- Integrated sealing and load distribution from the steel/rubber flat washer, minimizing vibration loosening and surface damage.
- Optimized thread engagement with 2" minimum thread length and partial threading, ensuring strong, stable connections in various material thicknesses.
- Precision right-hand threading with 10 threads per inch, delivering consistent, high-strength fastening for repetitive applications.
- Environmental compliance with RoHS 3 standards, making them safe for use in regulated industrial sectors.
Professional Applications & Engineering Value
These No. 14 zinc-plated steel tapping screws are engineered to address common challenges in sheet metal fastening, such as material splitting and thread stripping. The thread forming design creates strong, permanent threads in ductile materials, eliminating the need for separate tapping operations and reducing labor costs. The external hex drive ensures high torque transmission, preventing cam-out during installation, while the steel/rubber washer combines durability with vibration damping, ideal for industrial applications requiring secure, long-term performance. With a 4" length and partial threading, they provide versatile solutions for assembling varying thicknesses of sheet metal components in HVAC, automotive, and machinery assembly.
Specification Summary & Compliance
This product adheres to standard inch measurements with a thread diameter of 0.242" and Class 2A thread tolerances for consistent fit. It conforms to A/AB tapping screw standards for thread forming applications and is RoHS 3 (2015/863/EU) Compliant, ensuring it meets stringent environmental regulations for industrial use.
