S-95893A627 Length 1" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh environments and long-term reliability in plastic assemblies
• Enhanced torque transmission and reduced cam-out thanks to the T15 Torx drive, ensuring secure installation and preventing tool slippage
• Excellent holding power in plastic achieved through the TRS thread forming design and Tri-Lobe shank, which displaces material to create strong, vibration-resistant threads without pre-tapping
• Streamlined, low-profile installation with a standard flat head and 82° countersink angle, allowing the screw to sit flush with the material surface for a clean finish
• Full-length threading for maximum grip across the entire 1" length, providing consistent fastening strength along the entire engagement area
• Simplified assembly process with compatibility for a No. 29 drill bit (0.136" diameter), ensuring precise pilot holes for optimal performance in plastic substrates
• Compliance with global environmental standards including RoHS 3 and REACH, making these screws suitable for regulated industries and international supply chains

Professional Applications & Engineering Value

These No. 8-16 TRS thread forming screws are specifically engineered to address common challenges in plastic fastening, such as material cracking, strip-out, and loosening under vibration. The Tri-Lobe shank cross-section and thread forming (tapping) method compress and displace plastic material during installation, creating zero-clearance threads that significantly improve pull-out strength and resistance to back-out. Made from 18-8 stainless steel, they offer excellent corrosion resistance for outdoor enclosures, electrical housings, and automotive trim components. The T15 Torx drive allows for higher torque application compared to Phillips or slotted drives, reducing the risk of head stripping and ensuring consistent clamp load in production environments. Ideal for securing plastic panels, chassis, and assemblies where reliability and a flush finish are critical.

Specification Summary & Compliance

This No. 8-16 x 1" screw features a 0.164" thread diameter with 16 threads per inch and is fully threaded for maximum engagement. The flat head has a diameter of 0.312" and height of 0.1", designed with an 82° countersink angle for standard flush mounting. Manufactured to precise dimensional standards for reliable performance. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring adherence to strict substance restrictions for global market acceptance.
