S-99461A380 Length 7/8" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ensuring long-term reliability in various environments without rust or degradation.
• Efficient thread forming design with a tri-lobe shank that creates strong, permanent threads in plastic materials, reducing the risk of stripping and improving holding power.
• Easy installation and reduced tool wear thanks to the Phillips drive and No. 2 drive size, allowing for quick, secure fastening with common tools.
• Optimized for plastic applications with a blunt tip and fully threaded design, minimizing material cracking and providing consistent, reliable performance in assemblies.
• Wide compatibility and precise fit using a No. 29 drill bit (0.136" diameter), ensuring accurate hole sizing and reducing installation errors in plastic components.
• Environmental compliance assurance meeting RoHS 3 and REACH standards, making it safe for use in regulated industries and sustainable manufacturing processes.
• Durable pan head profile with a rounded design that distributes load evenly, enhancing grip and preventing damage to the screw head during repeated use.

Professional Applications & Engineering Value

This No. 8 x 7/8" tapping screw is engineered specifically for plastic fastening applications, where traditional screws often cause cracking or poor retention. Made from 18-8 stainless steel, it resists corrosion in humid or chemical exposures, extending service life in electronics, automotive trim, and consumer goods. The thread forming (TRS) technology and tri-lobe shank design displace material without cutting, creating tight, vibration-resistant threads that prevent loosening. Combined with a Phillips drive and pan head, it ensures quick installation and a flush finish, reducing assembly time and improving product integrity in plastic screws for industrial use.

Specification Summary & Compliance

This screw adheres to standard inch measurements with a thread diameter of 0.164" and approximately 16 threads per inch, ensuring precise fit in pre-drilled holes using a No. 29 drill bit. It features a right-hand thread direction, fully threaded length of 7/8", and a blunt tip for safe handling. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming it is free from hazardous substances and suitable for global environmental standards in manufacturing.
