S-90628A294 Length 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Enhanced corrosion protection with specialized coating extends service life in harsh industrial environments
• Superior sealing performance through integrated steel/rubber washer prevents moisture and contaminant ingress
• Efficient thread-forming installation creates strong, permanent threads without pre-drilling in steel and sheet metal
• Maximum drilling capability with 9/32" drill tip penetrates up to 0.187" thickness for versatile applications
• Secure external hex drive provides reliable torque transmission and prevents stripping during installation
• Full threading design ensures consistent grip strength along the entire 3/4" length for superior fastening
• BSD standard compliance guarantees interchangeability and reliable performance in industrial settings

Professional Applications & Engineering Value

These corrosion-resistant steel tapping screws solve critical fastening challenges in steel and sheet metal applications where environmental exposure and vibration resistance are paramount. The thread-forming BSD design eliminates the need for separate tapping operations, reducing installation time and labor costs while creating stronger thread engagement. The integrated steel/rubber sealing washer provides dual functionality - distributing clamp load while creating an effective environmental seal against moisture and contaminants. With their external hex drive and fully threaded No. 12-14 TPI configuration, these screws deliver exceptional pull-out resistance and maintain integrity in high-vibration environments, making them ideal for HVAC systems, electrical enclosures, and structural metal assemblies where reliability cannot be compromised.

Specification Summary & Compliance

This tapping screw features precision No. 12-14 TPI threading with standard right-hand direction and fully threaded 3/4" length. The screw maintains BSD standard specifications with 0.216" thread diameter and Class 2A thread tolerances for consistent performance. Manufacturing complies with RoHS and REACH environmental standards, while the corrosion-resistant coating and steel/rubber washer assembly meet industrial durability requirements for demanding applications in metal fabrication and construction sectors.
