Key Features & Benefits at a Glance
- Exceptional corrosion resistance with 316 stainless steel material, ideal for harsh environments and extended service life.
- Efficient thread forming design creates strong, permanent threads in sheet metal without pre-tapping, reducing installation time and tooling costs.
- Reliable Phillips drive system with No. 1 size ensures secure torque transmission and prevents cam-out during fastening.
- Standard pan head profile provides a low-profile, rounded finish for smooth surfaces and easy assembly with standard drivers.
- Full threading and pointed tip enable quick starts and consistent engagement across the entire 3/4" length for uniform clamping force.
- Optimized for 0.025" maximum drilling thickness using No. 44 drill bit (0.086" diameter), ensuring precise fits in sheet metal applications.
- Compliance with RoHS 3 and REACH regulations guarantees environmental safety and meets international standards for industrial use.
Professional Applications & Engineering Value
These 316 stainless steel tapping screws are engineered to address common challenges in sheet metal assembly, such as material fatigue and corrosion in demanding conditions. The thread forming technology (A/AB type) eliminates the need for separate tapping operations, reducing labor and potential thread damage. With a right-hand thread and 24 TPI configuration, they deliver high pull-out strength and vibration resistance, crucial for automotive, HVAC, and electronic enclosures. The Phillips drive and pan head design facilitate quick installation with standard tools, while the fully threaded shank ensures even stress distribution, preventing loosening and enhancing joint integrity in thin-gauge materials.
Specification Summary & Compliance
This screw adheres to inch system standards with a No. 4 size, 3/4" length, and Class 2A thread fit for reliable precision. It conforms to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring no hazardous substances. The thread forming tapping method and specified No. 44 drill bit size (0.086" diameter) support consistent performance in sheet metal up to 0.025" thickness, meeting industry benchmarks for durability and safety.
