Key Features & Benefits at a Glance
- Superior corrosion resistance with 316 stainless steel construction, ideal for harsh industrial environments and outdoor applications.
- Enhanced load distribution from the wide truss head design, reducing the risk of material pull-through in thin sheet metal.
- Efficient thread forming with 18 TPI and A/AB type, creating strong, reliable threads without pre-tapping for faster assembly.
- Secure and stable fastening thanks to the fully threaded shank and pointed tip, ensuring consistent grip in sheet metal up to 0.025" thick.
- Easy installation with No. 2 Phillips drive, compatible with standard tools for quick, slip-resistant driving.
- Precision fit with No. 6 diameter and compatibility with No. 32 drill bits, minimizing play and vibration loosening.
- Compliance assurance meeting RoHS 3 and REACH standards, supporting sustainable and safe manufacturing practices.
Professional Applications & Engineering Value
This 316 stainless steel tapping screw is engineered to address common challenges in sheet metal fabrication, such as material fatigue and corrosion in demanding settings. Its thread forming design eliminates the need for separate tapping operations, reducing assembly time and tooling costs while providing high clamp force. The wide truss head offers a larger bearing surface, distributing stress evenly to prevent sheet deformation and maintain joint integrity under dynamic loads. With a No. 2 Phillips drive and fully threaded shank, it ensures reliable performance in HVAC, electronics enclosures, and automotive panels, where vibration resistance and durability are critical. The 18 TPI fine thread and right-hand threading enhance grip in thin-gauge metals, making it a versatile choice for industrial fastening solutions.
Specification Summary & Compliance
This screw adheres to standard inch measurements with a No. 6 thread diameter (0.138") and 3/8" length, featuring fully threaded right-hand thread forming (A/AB type) at 18 TPI. It is designed for use with a No. 32 drill bit (0.116" diameter) in materials up to 0.025" thick. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), ensuring environmental and safety standards are met for industrial applications.
