• Versatile application compatibility specifically engineered for stainless steel and sheet metal fabrication projects

Professional Applications & Engineering Value

This heavy-duty tapping screw delivers exceptional engineering value by solving critical installation challenges in stainless steel and sheet metal applications. The combination of zinc-plated 410 stainless steel construction and thread forming design eliminates the need for separate tapping operations, significantly reducing assembly time and labor costs. The integrated drilling tip penetrates materials up to 0.048" thick without pre-drilling, preventing material deformation and ensuring precise hole alignment. The sealing washer with stainless steel/rubber composition provides reliable environmental protection against moisture and contaminants, making these BSD tapping screws ideal for outdoor equipment, HVAC systems, and industrial machinery where corrosion resistance and sealed joints are critical requirements.

Specification Summary & Compliance

This 1/4"-14 thread forming screw features precise Class 2A thread tolerances with right-hand orientation and fully threaded configuration. The external hex drive with 3/8" head width ensures compatibility with standard industrial tools. Manufactured to BSD tapping screw standards, the fastener incorporates a No. 1 drill tip type with 5/16" tip length for optimal penetration. The assembly includes a flat washer with 5/8" OD constructed from stainless steel and rubber materials. Compliant with industry standards for heavy-duty fastening applications, this corrosion-resistant solution meets quality requirements for industrial and construction use.
