S-90056A078 Length 5/16" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, extending service life in demanding industrial environments.
• Efficient thread forming action creates strong, permanent threads in sheet metal without pre-tapping, reducing assembly time and labor.
li>Reliable drive engagement with the Phillips No. 1 drive, minimizing cam-out and ensuring consistent torque application.
• Optimized for sheet metal with a blunt tip and 32 TPI fine threading, preventing material push-out and ensuring secure, vibration-resistant fastening.
• Full threading design provides maximum grip along the entire 5/16" length, enhancing pull-out strength in thin materials.
• Simplified installation using a standard No. 48 drill bit, streamlining the process and reducing tooling requirements.
• Compliance with environmental standards via RoHS 3, ensuring safe use in regulated industries and global markets.

Professional Applications & Engineering Value

These No. 2 zinc-plated steel tapping screws are precision-engineered for sheet metal applications, where traditional fasteners often strip threads or cause material fatigue. The thread forming design displaces material to create robust, load-bearing threads without chips, eliminating cleanup and enhancing joint integrity. The pan head with Phillips drive offers a low-profile, flush finish while resisting driver slippage during high-torque installation. Made from zinc-plated steel, they provide excellent resistance to rust and corrosion, making them ideal for HVAC assemblies, electronic enclosures, and automotive panels. Their fully threaded, blunt-tip construction ensures maximum holding power in thin-gauge metals, preventing loosening under vibration and reducing the need for additional locking hardware.

Specification Summary & Compliance

This screw features a No. 2 size with a 5/16" length and 32 TPI fine threading, adhering to standard inch measurements for precision fit. The thread forming Type B design and right-hand thread direction comply with industry-accepted tapping screw specifications. Manufactured to ensure dimensional accuracy, it requires a No. 48 drill bit (0.076" diameter) for proper hole preparation. The product is RoHS 3 (2015/863/EU) Compliant, meeting strict environmental regulations for hazardous substance restrictions, ensuring safety and suitability for global industrial use.
