S-90053A079 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
• Excellent thread-forming capability creates permanent, vibration-resistant threads in sheet metal without pre-tapping
• Optimized 32 TPI thread pitch delivers maximum holding power and pull-out resistance in thin materials
• Fully threaded pointed tip design ensures easy starting and rapid installation for increased assembly efficiency
• Standard pan head with slotted drive provides reliable engagement with common hand tools and drivers
• Precision-engineered dimensions (0.086" thread diameter, 3/8" length) ensure consistent performance in No. 48 drill bit applications
• Environmental compliance assurance meets RoHS 3 and REACH standards for responsible manufacturing

Professional Applications & Engineering Value

These No. 2 zinc-plated steel tapping screws are specifically engineered for demanding sheet metal applications where reliable fastening is critical. The thread forming technology eliminates the need for separate tapping operations, creating strong, permanent threads that resist loosening under vibration and thermal cycling. The A/AB type thread form with 32 TPI precision ensures optimal material engagement in thin gauge metals up to 0.025" thickness, while the fully threaded design with pointed tip facilitates quick starts and reduces installation time. The combination of zinc-plated corrosion protection and right-hand threading makes these screws ideal for HVAC systems, electronic enclosures, automotive components, and industrial equipment where durability and compliance with environmental standards are essential.

Specification Summary & Compliance

This thread forming tapping screw features precision Class 2A thread tolerances with 0.086" thread diameter and 32 TPI thread pitch. The screw meets industry-standard A/AB type thread forming specifications for sheet metal applications and is manufactured to work with No. 48 drill bits (0.076" diameter). Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in various industrial and commercial applications. The slotted pan head design provides reliable drive engagement while maintaining standard head dimensions (0.167" diameter, 0.053" height) for consistent performance across assembly operations.
