Key Features & Benefits at a Glance
- Superior corrosion resistance with 18-8 Stainless Steel construction, ensuring long-term reliability in harsh industrial environments.
- Exceptional holding power through thread forming technology, creating strong, permanent threads in sheet metal without pre-tapping.
- Streamlined installation with Phillips No. 3 drive and fully threaded design for quick, secure fastening in high-volume applications.
- Professional finish compatibility featuring an oval head with 82° countersink angle that sits flush for smooth, snag-free surfaces.
- Precision engineering with #14 screw size and 0.242" thread diameter, optimized for 0.025" maximum drilling thickness in sheet metal.
- Reduced assembly time using standard 5.5 mm drill bits, eliminating the need for specialized tools or complex preparation.
- Regulatory compliance assurance meeting RoHS 3 and REACH standards for safe, environmentally responsible manufacturing.
Professional Applications & Engineering Value
These 18-8 Stainless Steel oval head tapping screws deliver critical engineering advantages in sheet metal fabrication and assembly. The thread forming Type A/AB design eliminates common issues like strip-out and loose fittings by cold-forming mating threads that resist vibration and shock loads. The fully threaded #14 screws with Phillips drive ensure consistent engagement across the entire 3" length, providing uniform stress distribution in thin-gauge materials. This combination of stainless steel material and precision threading solves corrosion and strength challenges in HVAC, automotive, and electronics enclosures, while the oval head profile offers both aesthetic appeal and functional flush mounting.
Specification Summary & Compliance
Manufactured to precise inch system dimensions: 0.242" thread diameter, 10 threads per inch, and 3" fully threaded length. Features standard Type A/AB thread forming tapping method with right-hand direction and pointed tip for easy starting. Complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring restricted substance-free composition for industrial applications requiring regulatory adherence.
