S-92365A413 Length 5/8" Tapping Screws

Key Features & Benefits at a Glance

• Eliminates pre-drilling requirements with its integrated drilling tip that penetrates up to 0.08" thick steel and sheet metal, saving significant assembly time and labor.
• Superior corrosion resistance provided by the zinc-plated steel construction, ensuring long-term reliability in demanding industrial environments.
• Optimized torque transfer and reduced cam-out with the Phillips No. 1 drive, allowing for efficient and secure installation.
• Clean, flush finish achieved with the standard 82° flat head profile, ideal for applications where a smooth surface is critical.
• Exceptional holding power from the thread forming (Type BSD) design, which creates strong, permanent threads in ductile materials without chip removal.
• Maximum grip and fastening strength due to the fully threaded shank, distributing clamping force evenly along the entire length.
• Wide material compatibility for use in steel and sheet metal, making it a versatile fastener for various fabrication and assembly tasks.

Professional Applications & Engineering Value

This No. 4-24 thread forming tapping screw is engineered to solve critical challenges in metal assembly. Its zinc-plated steel material provides a durable barrier against rust, essential for components exposed to moisture or harsh conditions. The specialized drilling tip is a key innovation, allowing the screw to penetrate up to 0.08" thick steel and sheet metal without a pilot hole. This eliminates the separate drilling step, drastically reducing assembly time, minimizing tooling requirements, and preventing alignment errors. The BSD thread forming technology cold-forms mating threads as it's driven, resulting in zero chips and a vibration-resistant, high-strength connection that won't loosen over time. This makes it an indispensable fastener for HVAC ductwork, electrical enclosures, automotive panels, and machinery where speed, reliability, and a clean finish are paramount.

Specification Summary & Compliance

This fastener adheres to standard inch system dimensions: a No. 4 screw size with a 0.112" thread diameter and 24 threads per inch. The 5/8" length and fully threaded right-hand design ensure consistent performance. It features a standard 82° countersink angle for the flat head and a Phillips No. 1 drive. Manufactured as a Thread Forming Type BSD tapping screw, it is produced to common industrial standards for dimensional accuracy and performance in metal fastening applications.
