S-90077A298 Length 1 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, ensuring long-lasting performance in demanding industrial environments
• Efficient thread forming technology creates secure, permanent threads in sheet metal without pre-tapping, reducing installation time and labor costs
• Dual-drive Phillips/Slotted pan head provides versatile tool compatibility and prevents cam-out during high-torque applications
• Optimized 11 TPI thread pitch delivers excellent holding power and vibration resistance in thin sheet metal applications
• Full threading with pointed tip enables quick starts and smooth penetration through materials up to 0.025" thickness
• Precision dimensional control ensures consistent performance and reliable fit with standard 3/16" drill bits
• Comprehensive regulatory compliance meets RoHS 3 and REACH standards for global manufacturing and environmental safety

Professional Applications & Engineering Value

These No. 12 tapping screws are engineered specifically for sheet metal applications where reliability and installation efficiency are critical. The zinc-plated steel construction provides essential corrosion protection for outdoor equipment, HVAC systems, and industrial machinery exposed to harsh conditions. The thread forming design eliminates the need for separate tapping operations, creating strong, strip-resistant threads that maintain integrity under vibration and load stress. The A/AB tapping screw type with 0.216" thread diameter and 11 TPI precision ensures optimal material engagement in thin gauge metals, while the pan head profile with dual Phillips/Slotted drive accommodates various tool types for flexible assembly line operations. These characteristics make them ideal for manufacturing, construction, and metal fabrication where fast, secure fastening is paramount.

Specification Summary & Compliance

These sheet metal screws feature precise dimensional specifications including No. 12 screw size, 1-1/4" length, 0.216" thread diameter, and 11 TPI thread pitch. The thread forming tapping method follows industry standards for A/AB type screws, designed for use with 3/16" drill bits in materials up to 0.025" thickness. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and workplace safety compliance for global industrial applications.
