S-90055A152 Length 5/8" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding industrial environments
• Excellent thread-forming capability with Type B design creates strong, permanent threads in sheet metal without pre-tapping
• Optimal flush mounting achieved through standard flat head profile with 82° countersink angle for clean, professional finishes
• Enhanced driving efficiency with Phillips No. 2 drive that prevents cam-out and ensures secure installation
• Maximum holding power through fully threaded design that distributes load evenly across the entire fastener length
• Simplified installation process with compatible No. 32 drill bit size (0.116" diameter) for precise hole preparation
• Environmental compliance assurance with RoHS 3 certification for safe use in regulated applications

Professional Applications & Engineering Value

These zinc-plated steel tapping screws are specifically engineered for sheet metal applications where reliable fastening is critical. The thread forming Type B design eliminates the need for separate tapping operations, creating strong internal threads that resist vibration loosening. The fully threaded construction with blunt tip ensures maximum engagement in thin materials, while the 82° countersink angle provides a flush finish that meets professional appearance standards. The Phillips drive system offers familiar, efficient installation for production environments, making these self-tapping screws ideal for HVAC systems, electronic enclosures, and metal fabrication where durability and corrosion resistance are paramount.

Specification Summary & Compliance

This No. 6-20 x 5/8" tapping screw features precise 0.138" thread diameter with 20 threads per inch in right-hand direction, manufactured to standard inch system tolerances. The flat head design with standard profile ensures proper seating in prepared holes. Compliance with RoHS 3 (2015/863/EU) regulations guarantees environmental safety, while the thread forming method follows industry-standard Type B specifications for consistent performance in sheet metal applications requiring No. 32 drill bit preparation.
