S-90077A144 Length 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, ensuring long-lasting performance in demanding industrial environments.
• Effortless installation thanks to the thread-forming design and pointed tip, reducing assembly time and labor costs in sheet metal applications.
• Versatile drive compatibility with Phillips/Slotted No. 2 drive, allowing use with common tools for flexible on-site adjustments.
• Reliable thread engagement from the fully threaded No. 6 x 1/4" design, providing consistent holding power in materials up to 0.025" thickness.
• Enhanced durability with a rounded pan head profile, distributing load evenly and minimizing stress during tightening.
• Precision fit using standard No. 32 drill bits, ensuring accurate hole alignment and reducing the risk of material damage.
• Compliance assurance meeting RoHS 3 and REACH standards, supporting sustainable and safe manufacturing practices.

Professional Applications & Engineering Value

These No. 6 x 1/4" zinc-plated steel tapping screws are engineered to address common challenges in sheet metal applications, such as vibration loosening and material fatigue. The thread-forming A/AB tapping screw type creates strong, permanent threads without pre-tapping, saving time and reducing tool wear. With a right-hand thread direction and fully threaded design, they ensure uniform load distribution and high pull-out resistance in thin-gauge metals. The zinc-plated steel material offers excellent corrosion protection, while the Phillips/Slotted drive accommodates various tool types, making them ideal for HVAC, automotive, and electronics assembly where reliability and efficiency are critical.

Specification Summary & Compliance

This product adheres to standard inch measurements with a thread diameter of 0.138" and approximately 18 threads per inch, ensuring precise fit in sheet metal applications. It is designed for use with a No. 32 drill bit (0.116" diameter) and supports a maximum drilling thickness of 0.025". The screws comply with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing environmental safety and material quality for industrial use.
