Professional Applications & Engineering Value
Engineered for demanding steel and sheet metal applications, these corrosion-resistant steel tapping screws deliver exceptional performance where durability matters most. The thread-forming BSD design creates permanent, high-strength threads without the need for separate tapping operations, significantly reducing assembly time and labor costs. The integrated steel/rubber sealing washer provides reliable weatherproofing, making these screws ideal for outdoor enclosures, HVAC systems, and construction applications where moisture protection is critical. The self-drilling tip penetrates up to 0.21" thick materials, eliminating the two-step drilling and fastening process while maintaining structural integrity in sheet metal assemblies and structural steel connections.
Specification Summary & Compliance
This 1/4"-14 x 2" tapping screw features right-hand threads with approximately 14 threads per inch and meets standard dimensional requirements for industrial fastening applications. The screw incorporates a fully threaded shank with round cross-section and external hex drive for secure installation. Manufactured from corrosion-resistant coated steel with a flat washer featuring steel/rubber construction, this fastener is RoHS 3 (2015/863/EU) compliant for environmental safety and regulatory adherence in industrial settings.
