S-90065A112 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 industrial environments.
• Efficient thread forming design creates strong, permanent threads in sheet metal without pre-tapping, reducing assembly time and labor costs.
• Optimal flush mounting with standard flat head profile and 82° countersink angle for smooth, professional finishes in sheet metal applications.
• Enhanced driving stability provided by Phillips No. 1 drive size, minimizing cam-out and ensuring secure installation.
• Maximum grip strength through fully threaded design, distributing clamping force evenly across the entire fastener length.
• Precise compatibility with No. 44 drill bit (0.086" diameter) for 0.025" maximum drilling thickness, ensuring accurate hole preparation.
• Environmental compliance with RoHS 3 and REACH regulations, meeting international standards for hazardous substance restrictions.

Professional Applications & Engineering Value

These No. 4-24 thread forming tapping screws deliver exceptional engineering value in sheet metal applications where vibration resistance and material integrity are critical. The 18-8 stainless steel composition provides excellent corrosion resistance, making these Phillips flat head screws ideal for outdoor equipment, electrical enclosures, and HVAC systems. The Type A thread forming design eliminates the need for separate tapping operations, creating strong, strip-resistant threads that withstand dynamic loads. With fully threaded construction and precise 82° countersink angle, these fasteners ensure flush mounting while preventing material distortion in thin-gauge metals up to 0.025" thickness.

Specification Summary & Compliance

This No. 4-24 x 5/8" tapping screw features precision right-hand threads with 24 threads per inch and 0.112" thread diameter, manufactured to industry standards for thread forming applications. The fastener maintains dimensional accuracy with standard Class 2A thread tolerances and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. Designed specifically for use with No. 44 drill bits (0.086" diameter), these screws ensure proper fit and performance in sheet metal fastening applications requiring reliable, vibration-resistant connections.
