S-90065A318 Length 1 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh industrial environments and extended service life.
• Exceptional holding power in sheet metal due to the thread forming (Type A) design, which creates strong, secure threads without pre-tapping.
• Efficient and flush installation with a standard 82° flat head and Phillips drive, allowing for a clean finish and reduced risk of snagging.
• Full-length threading ensures maximum grip and uniform stress distribution along the entire 1-3/4" length for reliable fastening.
• Compliance with major environmental regulations including RoHS 3 and REACH, ensuring safety and suitability for global industrial supply chains.
• Optimized for thin materials, effectively fastening sheet metal up to 0.025" thick without compromising integrity.
• Broad compatibility with standard #3 Phillips drivers and 5.5mm drill bits, streamlining the assembly process.

Professional Applications & Engineering Value

These No. 14 Phillips flat head tapping screws are precision-engineered for demanding sheet metal applications, where vibration resistance and material integrity are critical. The 18-8 stainless steel provides excellent strength and corrosion resistance, preventing failure in humid or chemically aggressive environments. The thread forming (Type A) design is a key advantage, as it displaces material to create a tight, zero-clearance fit that resists loosening under dynamic loads. This eliminates the need for separate tapping operations, reducing assembly time and labor costs. The fully threaded shank and 82° countersink angle ensure a secure, flush mount in panels and enclosures, making these screws a reliable choice for HVAC systems, electronic chassis, and automotive assemblies where a smooth surface profile is required.

Specification Summary & Compliance

This screw is a No. 14 size with a length of 1-3/4" and features a right-hand thread with 10 threads per inch. The head is a standard flat head with a #3 Phillips drive. It is designed as a Thread Forming Type A tapping screw for use in materials like sheet metal, with a specified maximum drilling thickness of 0.025" using a 5.5mm (0.2165") drill bit. The product is manufactured to be RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, adhering to strict environmental and safety standards for industrial components.
