S-95893A385 Length 3/8" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, extending service life in demanding environments.
• Enhanced torque transmission and reduced cam-out provided by the T6 Torx drive, ensuring secure installation and preventing tool slippage.
• Excellent holding power in plastic materials due to the TRS thread-forming design and tri-lobe shank, which creates strong, lasting threads without pre-tapping.
• Streamlined, low-profile installation with a standard 82° flat head that sits flush with the material surface for a clean finish.
• Reliable, fully-threaded engagement along the entire 3/8" length, maximizing grip and pull-out resistance.
• Simplified assembly process as these screws form their own mating threads in plastics, eliminating the need for a separate tapping operation.
• Compliance with major environmental regulations including RoHS 3 and REACH, ensuring they are safe for use in regulated industries and global markets.

Professional Applications & Engineering Value

These No. 2 zinc-plated steel TRS thread-forming screws are engineered specifically for fastening into plastic materials, a common challenge where standard machine screws can cause cracking or stripping. The tri-lobe shank cross-section and thread-forming (TRS) tapping method displace plastic material during installation, creating a tight, zero-clearance fit that resists vibration loosening and provides exceptional pull-out strength. This design is critical in applications like automotive trim, electronic enclosures, and consumer appliances, where reliable fastening in plastic components is paramount. The T6 Torx drive offers superior control compared to Phillips or slotted drives, preventing damage to the screw head and the assembly during high-torque installation, thereby reducing waste and improving production line efficiency.

Specification Summary & Compliance
