S-90417A114 Length 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior thread retention in plastics with TRS thread-forming design that creates strong, permanent threads without chips
• Enhanced corrosion resistance through Black-Oxide Steel finish, providing durable protection in various environments
• Reduced installation torque thanks to the Tri-Lobe shank design that minimizes driving force while maintaining holding power
• Secure fastening in plastic assemblies with fully threaded configuration ensuring maximum engagement along the entire length
• Optimized drive performance featuring Phillips No. 1 drive for reliable torque transfer and reduced cam-out risk
• Precision compatibility with No. 43 drill bit (0.089") for proper hole sizing and optimal thread formation
• Environmental compliance assurance meeting RoHS 3 and REACH standards for global manufacturing requirements

Professional Applications & Engineering Value

Engineered specifically for plastic assembly applications, this No. 3 x 3/4" TRS tapping screw delivers exceptional performance where traditional fasteners fail. The thread-forming TRS design eliminates material chipping and stress cracking common in brittle plastics by displacing material rather than removing it. The Tri-Lobe shank cross-section reduces installation torque by up to 25% compared to standard thread-forming screws, preventing plastic boss damage during assembly. With 24 threads per inch and Black-Oxide Steel construction, these screws provide vibration resistance and corrosion protection ideal for electrical enclosures, automotive trim, consumer electronics, and industrial plastic components. The combination of Phillips drive and blunt tip ensures precise alignment and prevents material piercing in thin-walled applications.

Specification Summary & Compliance

This inch-system fastener features precision Class 2A thread tolerances with 0.099" thread diameter and 3/4" length. Manufactured to TRS tapping screw standards with right-hand threading and pan head style. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in global markets. The thread-forming tapping method requires no special tooling beyond standard Phillips No. 1 drivers and No. 43 drill bits for hole preparation.
