S-90380A115 Length 5/8" Tapping Screws

Key Features & Benefits at a Glance

• Superior holding power in plastic with TRS thread forming technology that eliminates the need for pre-drilling, reducing assembly time and labor costs.
• Enhanced corrosion resistance thanks to the zinc-plated steel construction, ensuring long-term durability in industrial environments.
• Efficient installation and reduced cam-out with the Phillips No. 1 drive, providing reliable torque transfer and minimizing tool slippage.
• Secure, vibration-resistant fastening due to the tri-lobe shank design, which creates a tight fit and prevents loosening in plastic materials.
• Consistent, precise threading with 20 TPI and fully threaded length, offering uniform load distribution and reliable performance in plastic assemblies.
• Compliance with environmental regulations including RoHS 3 and REACH, making these screws safe for use in various global markets and applications.
• Versatile application in plastic components from automotive to electronics, designed to handle everyday industrial stresses without failure.

Professional Applications & Engineering Value

This No. 4 x 5/8" zinc-plated steel TRS tapping screw is engineered to address common challenges in plastic fastening, such as material cracking and stripped threads. The thread forming design with a tri-lobe shank displaces plastic material to create strong, permanent threads without pre-drilling, reducing assembly steps and improving efficiency. Ideal for industrial applications in automotive trim, electronic enclosures, and consumer products, it ensures reliable performance under vibration and load. The Phillips drive facilitates quick installation, while the zinc-plated finish provides essential corrosion protection, extending service life in demanding environments.

Specification Summary & Compliance

This screw features a thread diameter of 0.112" with 20 TPI precision threading, fully threaded for consistent engagement. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety. Designed for use with a No. 37 drill bit (0.104" diameter), it adheres to standard thread forming practices for plastic materials, providing reliable fastening without additional tapping requirements.
