S-90935A101 Length 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior sheet metal penetration with thread forming design that creates strong, permanent threads without chips
• Enhanced corrosion resistance from black-oxide steel construction for extended service life in industrial environments
• Optimized drive efficiency with Phillips No. 1 drive that prevents cam-out and ensures secure installation
• Maximum material engagement through fully threaded design that provides consistent holding power along entire length
• Precision thread formation with 32 TPI and A/AB thread profile for secure fastening in thin sheet metal up to 0.025"
• Streamlined installation process with pre-specified No. 48 drill bit size (0.076" diameter) for perfect hole preparation
• Environmental compliance assurance with RoHS 3 certification for use in regulated industries worldwide

Professional Applications & Engineering Value

These No. 2 x 1/4" Phillips pan head tapping screws deliver exceptional performance in sheet metal assembly applications where traditional fastening methods fall short. The A/AB thread forming technology eliminates the need for tapped holes while creating stronger thread engagement through material displacement rather than removal. This black-oxide steel construction provides a durable, corrosion-resistant finish that withstands harsh industrial environments. The fully threaded design ensures maximum holding power across the entire fastener length, while the 32 TPI precision threading offers fine adjustment capability in thin materials. These thread forming sheet metal screws solve common challenges like strip-out, cross-threading, and insufficient thread engagement in lightweight metal assemblies, making them ideal for HVAC systems, electronic enclosures, and automotive components where reliability is critical.

Specification Summary & Compliance

These precision-engineered fasteners feature a No. 2 screw size with 1/4" length and Class 2A thread fit for reliable performance. The A/AB thread forming standard ensures consistent thread creation in pre-drilled holes using a No. 48 drill bit (0.076" diameter). Manufacturing complies with industry standards for tapping screw applications, and the products are fully RoHS 3 (2015/863/EU) Compliant, meeting stringent environmental regulations for hazardous substance restrictions in electronic and industrial equipment.
