S-95638A322 Length 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior tamper resistance with specialized T8 Torx drive that prevents unauthorized removal in security-sensitive applications
• Excellent corrosion resistance thanks to 18-8 stainless steel construction, ensuring long-term reliability in harsh environments
• Optimized thread forming design creates strong, permanent threads in sheet metal without requiring pre-tapped holes
• Maximum material engagement through fully threaded shank design for superior holding power in thin materials
• Streamlined installation process with pointed tip that self-starts in pre-drilled 3/32" holes for faster assembly
• Secure rounded head profile provides a finished appearance while accommodating standard button head applications
• Reliable performance in thin materials specifically engineered for sheet metal applications up to 0.025" thickness

Professional Applications & Engineering Value

These No. 4-24 thread forming screws deliver exceptional value in industrial settings where security and durability are paramount. The 18-8 stainless steel construction provides outstanding corrosion resistance for outdoor equipment, electronic enclosures, and HVAC systems exposed to moisture and chemicals. The tamper-resistant Torx T8 drive addresses critical security needs in public infrastructure, transportation, and access control systems where unauthorized tampering must be prevented. The thread forming design (A/AB type) eliminates the need for separate tapping operations in sheet metal assemblies, reducing installation time and labor costs while creating stronger, more reliable threads that won't strip or loosen under vibration. The combination of fully threaded shanks and pointed tips ensures quick starts and maximum thread engagement in materials up to 0.025" thick, making these tapping screws ideal for thin-gauge metal fabrication, electrical boxes, and precision mechanical assemblies.

Specification Summary & Compliance

These security fasteners feature precision No. 4-24 thread size with right-hand direction and Class 2A thread tolerances for consistent performance. The thread forming (A/AB) tapping method complies with industry standards for sheet metal applications, requiring a 3/32" (0.0938") drill bit for proper installation. Manufactured from 18-8 stainless steel with fully threaded design and 1/2" length, these screws maintain dimensional accuracy throughout production. The tamper-resistant Torx T8 drive system meets security fastener specifications, while the material composition ensures compliance with RoHS and REACH environmental standards for industrial use.
