S-90190A024 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 technology creates strong, permanent threads in sheet metal without pre-tapping requirements
• Optimized 52 TPI thread pitch delivers maximum holding power and vibration resistance in thin materials
• Easy installation with pointed tip design that self-starts and Phillips No. 0 drive for secure tool engagement
• Full threading along 3/8" length ensures complete material engagement and consistent clamping force
• Pan head design provides low-profile fastening with excellent bearing surface for sheet metal applications
• Precision compatibility with No. 55 drill bit (0.052") for optimal performance in materials up to 0.025" thickness

Professional Applications & Engineering Value

These zinc-plated steel tapping screws are engineered specifically for sheet metal applications where reliable fastening in thin materials is critical. The thread forming technology eliminates the need for separate tapping operations, significantly reducing assembly time and labor costs. The A/AB tapping screw type with 52 TPI precision threading creates strong, load-bearing threads that resist loosening under vibration, making them ideal for HVAC systems, electronic enclosures, and automotive components. The fully threaded design ensures maximum thread engagement throughout the material thickness, while the pointed tip facilitates easy alignment and starts without walking. This combination of features solves common industrial challenges of strip-out, cross-threading, and insufficient holding power in thin-gauge metals.

Specification Summary & Compliance

This No. 0 x 3/8" tapping screw features precision thread forming technology with 0.06" thread diameter and 52 TPI thread pitch following standard inch measurements. The screw maintains tight dimensional tolerances with right-hand threading and fully threaded shank for consistent performance. Manufactured from zinc-plated steel with pan head style and Phillips No. 0 drive, this fastener is RoHS 3 (2015/863/EU) Compliant, ensuring environmental regulatory compliance for industrial and commercial applications worldwide.
