S-90066A316 Length 1 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, ensuring long-term durability in industrial environments
• Enhanced holding power through fully threaded design and 10 threads per inch, providing maximum grip in sheet metal applications
• Efficient installation with external hex drive and 3/8" head width, allowing for quick assembly with standard tools
• Integrated load distribution from the steel/rubber flat washer, reducing surface damage and improving joint integrity
• Self-tapping thread forming design (Type A/AB) eliminates the need for pre-tapped holes, cutting installation time and labor costs
• Precision compatibility with 5.5mm drill bits, ensuring accurate fit and reduced material stress during drilling
• Versatile pointed tip facilitates easy insertion and alignment in sheet metal up to 0.025" thickness

Professional Applications & Engineering Value

These No. 14 thread forming tapping screws are engineered to address common challenges in sheet metal assembly, such as material fatigue and loosening under vibration. The zinc-plated steel construction provides a protective barrier against rust, extending service life in demanding conditions. The thread forming design creates strong, permanent threads in ductile materials without chip removal, reducing the risk of contamination. Combined with the integrated flat washer, these screws distribute clamping force evenly, preventing surface deformation and maintaining structural integrity in HVAC, automotive, and electrical enclosure applications where reliable fastening is critical.

Specification Summary & Compliance

Manufactured to industry standards for tapping screws, these fasteners feature a right-hand thread with a diameter of 0.242" and comply with standard inch measurements. The thread forming (Type A/AB) design adheres to recognized specifications for self-tapping performance. Components meet material safety requirements, with RoHS and REACH compliance for environmental and workplace safety. Precision manufacturing ensures consistent fit with 5.5mm drill bits, supporting efficient, repeatable assembly processes.
