S-93882A149 6-32 x 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Enhanced corrosion resistance with zinc-plated steel construction, extending service life in demanding industrial environments.
• Superior holding power and vibration resistance from the integrated flange design, reducing the risk of loosening under stress.
• Efficient, high-torque installation enabled by the external hex head, allowing for quick and secure fastening with standard tools.
• Reliable thread formation in various materials including steel, aluminum, and sheet metal, thanks to the UNC coarse thread and thread-forming tapping method.
• Full-length threading ensures maximum grip and load distribution along the entire shank for robust assemblies.
• Simplified compliance for global projects by meeting RoHS 3 and REACH environmental regulations, ensuring safe and sustainable use.
• Broad material compatibility with steel, aluminum, brass, cast iron, and sheet metal, offering versatile application across industries.

Professional Applications & Engineering Value

This zinc-plated steel flanged tapping screw is engineered to address common challenges in industrial assembly, such as material fatigue and fastener loosening. The thread-forming (SW type) design with UNC coarse threads creates strong, permanent threads in ductile metals like steel, aluminum, and brass, eliminating the need for pre-tapped holes and reducing installation time. The flange distributes clamping force evenly, minimizing surface damage and enhancing joint integrity in sheet metal and cast iron applications. With a blunt tip and fully threaded shank, it provides consistent engagement and resists back-out, making it ideal for high-vibration environments in automotive, machinery, and construction sectors.

Specification Summary & Compliance

This screw adheres to UNC thread standards with a size of 6-32 and coarse spacing, ensuring precise fit and interchangeability. Dimensions include a 1/4" hex head width, 3/4" length, and 0.138" thread diameter, compatible with a No. 31 drill bit (0.12" diameter) for optimal performance. It is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, supporting environmental safety and regulatory requirements in industrial fastener applications.
