S-90056A077 Length 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in industrial environments
• Efficient thread forming action creates precise mating threads without chip removal in sheet metal applications
• Optimized drive engagement with Phillips No. 1 drive prevents cam-out and ensures secure fastening control
• Full 32 TPI threading provides maximum thread engagement and superior pull-out resistance
• Blunt tip design enables easier starting and reduces material deformation during installation
• Standard pan head profile offers excellent bearing surface for consistent clamping force distribution
• Environmental compliance with RoHS 3 standards ensures safe use across regulated industries

Professional Applications & Engineering Value

These thread forming tapping screws deliver exceptional performance in sheet metal applications where traditional fastening methods often struggle. The zinc-plated steel construction provides reliable corrosion protection while maintaining the necessary strength for demanding industrial environments. The thread forming design eliminates the need for pre-tapped holes, creating strong, permanent threads in base materials without generating metal chips that could compromise electrical components or moving parts. With 32 TPI precision threading and Phillips drive compatibility, these screws ensure consistent installation torque and reliable clamping force in assembly operations. The fully threaded configuration and blunt tip design facilitate easier alignment and reduce the risk of cross-threading, making them ideal for high-volume production environments where speed and reliability are critical.

Specification Summary & Compliance

These No. 2 tapping screws feature a 0.086" thread diameter with 32 threads per inch precision threading, 1/4" length, and standard pan head design with 0.167" head diameter. Manufactured to industry standards for thread forming applications in sheet metal with recommended No. 48 drill bit (0.076" diameter) for proper hole preparation. The screws are fully compliant with RoHS 3 (2015/863/EU) environmental regulations and feature right-hand threading with Class 2A thread tolerances for consistent performance across industrial applications.
