S-99461A460 Length 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior holding power in plastic materials thanks to the tri-lobe shank design that displaces material to create secure, vibration-resistant threads.
• Excellent corrosion resistance provided by 18-8 Stainless Steel construction, ensuring long-term reliability in various environments.
• Efficient and quick installation with the Phillips No. 2 drive and thread forming (TRS) design, reducing assembly time and eliminating the need for a separate tapping operation.
• Reduced risk of material cracking during installation with the blunt tip, making it ideal for delicate plastic components.
• Full-length threading for maximum grip and load distribution along the entire fastener length in plastic assemblies.
• Compatibility with standard No. 21 drill bits simplifies the pre-drilling process and ensures a precise fit for optimal performance.
• Compliance with major environmental regulations including RoHS 3 and REACH, making them suitable for global supply chains and sensitive applications.

Professional Applications & Engineering Value

This No. 10 x 3/4" TRS Phillips Pan Head Tapping Screw is engineered specifically for plastic fastening applications where reliability and material integrity are paramount. The thread forming (TRS) design with its tri-lobe shank cold-forms mating threads in plastic, creating a strong, strip-resistant connection without generating chips that could cause electrical shorts or contamination. Made from 18-8 Stainless Steel, it offers excellent resistance to corrosion and oxidation, ensuring longevity in humid or chemically exposed environments common in electronics enclosures, automotive trim, and consumer appliances. The Phillips drive and pan head provide a balance of installation torque and a low-profile, finished appearance, while the blunt tip prevents piercing through thin plastic walls, reducing assembly failures and rework costs.

Specification Summary & Compliance

This screw features a No. 10 size with a 3/4" length, 0.19" thread diameter, and 14 threads per inch. It is fully threaded with a right-hand thread direction and is designed for use with a No. 21 drill bit (0.159" diameter). The fastener complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring it is free from hazardous substances and suitable for use in regulated industries.
