S-94155A094 Length 5/8" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ensuring long-term reliability in harsh environments.
• Excellent thread-forming capability with Type A/AB design, creating strong, permanent threads in sheet metal without pre-tapping.
• Maximum holding power through fully threaded shank design, providing consistent grip along the entire 5/8" length.
• Easy installation and removal with square drive and pan head, offering secure tool engagement and reduced cam-out risk.
• Precision compatibility with No. 44 drill bits (0.086" diameter), optimized for 0.025" maximum drilling thickness in sheet metal.
• Regulatory compliance assurance meeting RoHS 3 and REACH standards, supporting sustainable and safe manufacturing practices.
• Versatile right-hand threading with 24 TPI fine pitch, delivering secure fastening in various sheet metal thicknesses.

Professional Applications & Engineering Value

These thread forming tapping screws are engineered to solve common industrial challenges in sheet metal assembly, where traditional fasteners may strip threads or require additional tapping operations. The 18-8 stainless steel composition provides exceptional resistance to oxidation and chemical exposure, making these screws ideal for outdoor equipment, HVAC systems, and electronic enclosures. The Type A/AB thread forming design displaces material during installation, creating a tight, vibration-resistant fit that eliminates the need for lock washers. With a 0.112" thread diameter and fully threaded construction, they ensure uniform stress distribution and prevent loosening under dynamic loads, reducing maintenance cycles and improving product lifespan in sheet metal applications.

Specification Summary & Compliance

This No. 4-24 x 5/8" sheet metal tapping screw features inch system measurements with a thread diameter of 0.112" and 24 threads per inch fine pitch. Manufacturing adheres to standard thread forming specifications for Type A/AB tapping screws, ensuring consistent performance in sheet metal up to 0.025" thickness when used with a No. 44 drill bit. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of restricted substances and supporting global supply chain requirements.
