S-99461A201 Length 5/8" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for humid or demanding industrial environments
• Excellent holding power in plastic due to the tri-lobe shank design, which forms strong, secure threads without pre-tapping
• Easy and efficient installation with the Phillips #1 drive, reducing tool slippage and assembly time
• Maximum material engagement from fully threaded design, ensuring a reliable, vibration-resistant fastening
• Reduced risk of material splitting with a blunt tip, making it safer for use in various plastic types
• Compliance with strict environmental regulations, including RoHS 3 and REACH, for safe use in global markets
• Precise fit and consistent performance with standardized inch dimensions (0.086" diameter, 5/8" length) for reliable replacements

Professional Applications & Engineering Value

This 18-8 stainless steel TRS tapping screw is specifically engineered for plastic fastening applications, where traditional screws may strip or fail. The thread-forming tri-lobe shank displaces plastic material to create strong, permanent internal threads, eliminating the need for separate inserts and reducing assembly costs. Its right-hand thread and Phillips drive ensure straightforward installation with standard tools, while the blunt tip minimizes stress cracking in brittle plastics. Ideal for electronics enclosures, automotive components, and consumer goods, this screw provides a durable, vibration-resistant connection that maintains integrity under thermal cycling and mechanical loads, thanks to the corrosion-resistant stainless steel material.

Specification Summary & Compliance

This screw features a 0.086" thread diameter with approximately 28 threads per inch and a 5/8" length, designed as a No. 2 screw size with a pan head and Phillips #1 drive. It complies with common industrial standards for thread-forming screws used in plastics and is RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, ensuring it meets environmental and safety regulations for hazardous substances.
