S-99461A579 Length 1" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 Stainless Steel material, ideal for harsh or outdoor environments where moisture and chemicals are present.
• Excellent holding power in plastic due to the thread forming (TRS) design, which creates strong, permanent threads without chipping or cracking the material.
• Efficient and secure installation with the Phillips No. 2 drive, providing common tool compatibility and reducing cam-out risks during driving.
• Enhanced drive stability and reduced stripping from the Tri-Lobe shank cross-section, which helps prevent rotation in the mounting hole.
• Reliable, fully threaded engagement along the entire 1" length, ensuring consistent clamping force and vibration resistance in plastic assemblies.
• Simplified sourcing and compliance by meeting RoHS 3 and REACH environmental regulations, making them suitable for global industrial supply chains.
• Optimized for precise fit with recommended No. 21 drill bit (0.159" diameter), facilitating quick and accurate installation in plastic applications.

Professional Applications & Engineering Value

These No. 10 x 1" TRS tapping screws are precision-engineered for demanding plastic fastening applications, where material integrity and long-term performance are critical. The 316 Stainless Steel construction provides exceptional resistance to corrosion, making these screws ideal for electronics enclosures, marine components, and chemical processing equipment. The thread forming technology and Tri-Lobe shank design work in tandem to displace plastic material without creating chips, thereby eliminating weak points and ensuring a tight, reliable fit that withstands vibration and thermal cycling. This design is particularly valuable in industrial settings, reducing assembly time and the need for additional locking hardware, while the Phillips drive offers broad compatibility with standard tools for efficient production line use.

Specification Summary & Compliance

This screw features a No. 10 size with a 0.19" thread diameter and 14 threads per inch, fully threaded for consistent engagement. It complies with common inch-series dimensional standards for tapping screws and is manufactured for use with a No. 21 drill bit. The product is confirmed to be RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, ensuring adherence to strict environmental and safety regulations for industrial components.
