S-99461A576 Length 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 Stainless Steel construction, ideal for harsh environments and extended service life in plastic assemblies.
• Excellent holding power and vibration resistance due to the Tri-Lobe shank cross-section, which forms strong, reliable threads in plastic materials.
• Efficient and secure installation with a Phillips No. 2 drive, providing common tool compatibility and reducing cam-out during fastening.
• Optimized for plastic applications using thread forming (TRS) technology, which creates precise threads without generating chips, preventing material damage.
• Full threading for maximum grip along the entire 3/4" length, ensuring uniform stress distribution and a secure fastening in various plastic thicknesses.
• Simplified drilling process with a recommended No. 21 drill bit (0.159" diameter), enabling quick and accurate pilot hole preparation.
• Compliance with global environmental standards including RoHS 3 and REACH, ensuring safety and regulatory acceptance for industrial use.

Professional Applications & Engineering Value

This No. 10 TRS tapping screw is specifically engineered for plastic applications, where traditional fasteners may strip or fail. The thread forming design with a Tri-Lobe shank displaces material to create strong, permanent threads, eliminating the need for inserts and reducing assembly time. Made from 316 Stainless Steel, it offers exceptional resistance to chemicals and moisture, making it perfect for outdoor equipment, electrical enclosures, and automotive components. The Phillips drive ensures widespread tool compatibility, while the blunt tip and precise 14 TPI threads provide controlled penetration without cracking brittle plastics, enhancing reliability in high-vibration environments.

Specification Summary & Compliance

This screw adheres to standard inch measurements with a No. 10 thread diameter (0.19") and 3/4" length, featuring a right-hand thread and fully threaded construction for consistent performance. It is designed as a thread forming (TRS) tapping screw with a Tri-Lobe shank cross-section, ensuring secure fastening in plastics. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), confirming it is free from hazardous substances and suitable for industrial and consumer applications requiring environmental safety.
