S-93882A235 8-32 x 3/8" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, ensuring long-lasting performance in harsh industrial environments.
• High torque transmission via the external hex drive design, allowing for secure installation and removal without stripping.
• Enhanced load distribution from the integrated flange, reducing the risk of material damage and improving joint integrity.
• Reliable thread forming capability with UNC coarse threading, creating strong, permanent threads in materials like steel and aluminum without pre-tapping.
• Wide material compatibility for use in steel, aluminum, brass, cast iron, and sheet metal, offering versatility across various applications.
• Precise installation facilitated by the fully threaded blunt tip and compatibility with a No. 26 drill bit (0.146" diameter), ensuring accurate placement.
• Durable and vibration-resistant right-hand thread design, maintaining tight fastening under dynamic loads and reducing loosening over time.

Professional Applications & Engineering Value

This 8-32 UNC zinc-plated steel flanged hex tapping screw is engineered to address common challenges in industrial assembly, such as material fatigue and thread stripping. Its thread forming (SW) design eliminates the need for pre-tapped holes, creating robust threads directly in ductile materials like steel, aluminum, and sheet metal, which reduces installation time and costs. The external hex drive ensures maximum torque application, ideal for high-stress environments, while the flange distributes clamping force evenly, preventing surface damage and improving seal integrity. With a coarse UNC thread and blunt tip, it provides reliable fastening in applications requiring vibration resistance and precise alignment, making it a go-to solution for machinery, automotive, and metal fabrication sectors.

Specification Summary & Compliance
