S-90315A471 Length 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for demanding industrial environments and long-term reliability.
• Efficient, secure installation using the Phillips No. 2 drive, reducing cam-out and tool slippage for consistent, high-quality assemblies.
• Excellent material displacement and strong thread engagement from the thread forming (A/AB Type) design, creating durable, vibration-resistant connections in sheet metal without pre-tapping.
• Clean, finished appearance and flush seating provided by the standard oval head, which sits neatly in countersunk holes with an 82° angle.
• Full-length threading and a pointed tip for faster starts and easier driving, maximizing assembly speed and reducing operator fatigue.
• Reliable performance in thin materials, designed for a maximum drilling thickness of 0.025", making them perfect for precise sheet metal applications.
• Compliance with major environmental and safety regulations including RoHS 3 and REACH, ensuring they meet global standards for industrial use.

Professional Applications & Engineering Value

These No. 8 x 3/4" oval head tapping screws are precision-engineered from 18-8 stainless steel to solve common challenges in sheet metal assembly. The thread forming (A/AB Type) technology displaces material to create strong, permanent threads without generating chips, eliminating the need for pre-tapped holes and reducing assembly time and cost. The fully threaded design with a pointed tip ensures quick starts and consistent engagement, even in thin-gauge metals up to 0.025" thick. The Phillips No. 2 drive offers reliable torque transfer, minimizing the risk of stripping and ensuring a secure fit in high-vibration environments. Ideal for HVAC, electronics enclosures, and automotive panels, these screws provide a durable, corrosion-resistant fastening solution that maintains integrity under stress.
