S-90190A079 Length 3/8" 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 design creates strong, permanent threads in sheet metal without pre-tapping requirements
• Optimized for 0.025" maximum drilling thickness providing reliable performance in standard sheet metal applications
• Precision Phillips No. 1 drive ensures secure tool engagement and reduces cam-out during installation
• 32 TPI fine threading delivers excellent holding power and vibration resistance in thin materials
• Fully threaded shank maximizes grip length and distributes stress evenly across the entire fastener
• RoHS 3 compliance meets international environmental standards for hazardous substance restrictions

Professional Applications & Engineering Value

These No. 2 zinc-plated steel tapping screws are engineered specifically for sheet metal applications where reliability and installation efficiency are critical. The thread forming design eliminates the need for separate tapping operations, significantly reducing assembly time and labor costs. The zinc-plated steel construction provides essential corrosion protection for industrial environments, while the Phillips drive ensures consistent torque application without specialized tools. With their 0.086" thread diameter and 32 TPI precision threading, these A/AB tapping screws create secure, vibration-resistant connections in metal fabrication, HVAC systems, electrical enclosures, and automotive components. The fully threaded design and pointed tip facilitate quick starts and smooth penetration through pre-drilled holes using standard No. 48 drill bits.

Specification Summary & Compliance

These sheet metal screws feature precision Class 2A thread tolerances with right-hand threading and 0.086" thread diameter. The tapping screw type A/AB designation confirms compliance with industry standards for thread forming fasteners. Manufacturing follows established specifications for pan head profile with 0.167" head diameter and 3/8" length. The products are RoHS 3 (2015/863/EU) Compliant, ensuring they meet current environmental regulations for hazardous substance restrictions in electronic and industrial applications.
