S-90065A242 Length 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Corrosion-resistant 18-8 Stainless Steel construction ensures long-term reliability in harsh industrial environments, reducing replacement costs and maintenance downtime.
• Thread forming (Type A) design creates strong, permanent threads in sheet metal without chips, eliminating cleanup and providing superior vibration resistance.
• 82° undercut flat head with Phillips No. 2 drive offers flush installation for smooth surfaces and secure, slip-resistant torque application during assembly.
• Fully threaded shank and pointed tip maximizes grip length and enables easier starting, ensuring consistent holding power across the entire fastener length.
• Precision-engineered No. 10-12 thread with 1/2" length delivers optimal pull-out strength and reliable performance in standard 0.025" sheet metal applications.
• Compliance with RoHS 3 and REACH regulations guarantees environmentally safe materials meeting global industrial standards for sustainable operations.
• Compatible with No. 21 drill bit (0.159" diameter) simplifies installation planning and reduces preparation time with standardized drilling requirements.

Professional Applications & Engineering Value

These 18-8 stainless steel Phillips flat head tapping screws are engineered to address common challenges in sheet metal assembly, where vibration loosening and corrosion are primary concerns. The thread forming technology (Type A) cold-forms material without creating chips, preventing electrical shorts and contamination in sensitive equipment. The undercut flat head profile with 82° countersink ensures a flush finish that won't interfere with moving components, while the fully threaded design provides uniform stress distribution to prevent joint failure. Ideal for HVAC systems, electronic enclosures, and automotive panels, these RoHS and REACH compliant screws maintain integrity in temperature-variable and corrosive environments, reducing lifecycle costs through exceptional durability and chemical resistance.

Specification Summary & Compliance
