S-93880A581 Length 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, extending service life in demanding industrial environments
• Maximum torque transmission through external hex drive design, preventing tool slippage during high-tension installations
• Enhanced load distribution with integrated flange, reducing surface pressure and preventing material deformation in sheet metal
• Optimized thread forming action with Type B tapping design, creating strong, permanent threads without pre-tapped holes
• Full-length threading ensures consistent engagement along the entire fastener length for maximum holding power
• Precision dimensional compatibility with 6.9mm drill bits, ensuring perfect fit and reduced installation errors
• Right-hand thread direction provides standard, intuitive installation for efficient assembly line operations

Professional Applications & Engineering Value

These 5/16"-12 thread forming tapping screws deliver exceptional performance in sheet metal applications where traditional fasteners often fail. The zinc-plated steel construction provides essential corrosion protection for industrial environments, while the external hex drive enables high-torque installation without cam-out issues. The integrated flange design eliminates the need for separate washers, distributing clamp load over a wider area to prevent sheet metal distortion. As thread forming screws, they create precise mating threads in parent material through cold flow, resulting in superior pull-out resistance compared to thread-cutting alternatives. This makes them ideal for HVAC systems, electrical enclosures, and metal fabrication where vibration resistance and structural integrity are critical.

Specification Summary & Compliance

These flanged hex tapping screws feature precision 5/16"-12 UNC threads with standard right-hand direction and full threading along the 3/4" length. Manufactured to industry standards for Type B thread forming screws, they maintain consistent dimensional accuracy for reliable performance. The zinc plating surface treatment provides corrosion protection while complying with industrial fastener specifications. These screws are engineered for use with standard 6.9mm drill bits (0.2717") and are suitable for various sheet metal thicknesses and industrial applications requiring durable, high-performance fastening solutions.
