S-90315A589 Length 1 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Corrosion-resistant 18-8 stainless steel construction ensures long-term durability and reliability in demanding industrial environments.
• Thread forming (Type A/AB) design creates strong, permanent threads in sheet metal without pre-tapping, reducing installation time and tooling costs.
• Oval head with standard profile and 82° countersink angle provides a flush, finished appearance while preventing snagging and improving safety.
• Phillips No. 3 drive offers secure bit engagement and efficient installation with common tools, minimizing cam-out and driver slippage.
• Fully threaded shank and pointed tip ensure maximum grip and easy starting in materials up to 0.025" thick for consistent fastening performance.
• Precision inch dimensions (No. 14 x 1-1/2") guarantee reliable fit and compatibility with standard 5.5 mm drill bits for accurate hole preparation.
• RoHS 3 and REACH compliance meets stringent environmental regulations, making these screws suitable for global supply chains and sensitive applications.

Professional Applications & Engineering Value

These 18-8 stainless steel oval head tapping screws are engineered specifically for sheet metal applications where corrosion resistance, strength, and installation efficiency are critical. The thread forming technology (Type A/AB) eliminates the need for separate tapping operations by cold-forming mating threads directly into the base material, reducing assembly steps and potential for cross-threading. The combination of a fully threaded design and 82° countersink angle ensures a secure, flush fit that withstands vibration and load stresses in enclosures, HVAC systems, and electronic chassis. The Phillips No. 3 drive provides reliable torque transfer for high-volume production environments, while the stainless steel material maintains integrity in humid or chemically exposed conditions, delivering long-term performance without galvanic corrosion concerns.
