- Effortless installation and secure fastening thanks to the Phillips drive and thread forming design, reducing assembly time and tool wear.
- Optimal material displacement and strong thread engagement with 24 TPI precision and fully threaded shank, ensuring reliable performance in sheet metal up to 0.025" thickness.
- Clean, flush finish with an 82° countersink angle and standard oval head profile, enhancing aesthetic appeal and safety by minimizing protrusions.
- Wide compatibility and ease of use with No. 44 drill bit size and right-hand threading, streamlining integration into existing assembly processes.
- Compliance with global environmental standards including RoHS 3 and REACH, ensuring safe and sustainable sourcing for B2B procurement.
Professional Applications & Engineering Value
These No. 4 x 3/4" Phillips Oval Head Thread Forming Screws are engineered to address common challenges in sheet metal assembly, such as material cracking and loose fasteners. The Black-Oxide Steel construction provides enhanced durability against rust and wear, while the thread forming (A/AB type) design creates strong, permanent threads without chips, reducing the risk of failure in thin-gauge metals. With a pointed tip and precise 24 TPI threading, they ensure quick starts and consistent holding power, ideal for HVAC, automotive, and electronics enclosures where vibration resistance and a smooth finish are critical for long-term reliability.
Specification Summary & Compliance
This product adheres to standard inch measurements with a thread diameter of 0.112" and length of 3/4", featuring fully threaded, right-hand threads for uniform engagement. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety. The design supports a maximum drilling thickness of 0.025" with a No. 44 drill bit (0.086" diameter), and the 82° countersink angle facilitates proper seating in sheet metal applications, meeting industry expectations for precision and performance.
