Professional Applications & Engineering Value

Engineered specifically for plastic fastening applications, this 410 Stainless Steel tapping screw delivers exceptional value in industrial assembly operations. The thread cutting design eliminates the need for pre-tapped holes, significantly reducing installation time and labor costs while providing secure, vibration-resistant connections. The Phillips drive system ensures consistent torque transmission during high-volume assembly, while the pan head profile offers a low-profile finish that sits flush against plastic surfaces. This self-tapping screw is particularly valuable in electronics enclosures, automotive plastic components, and consumer products where reliable plastic-to-plastic or plastic-to-metal fastening is critical. The combination of stainless steel durability and specialized thread forming capability addresses common challenges of strip-out and material fatigue in plastic assemblies.

Specification Summary & Compliance

This No. 4-24 x 3/8" tapping screw features precise inch system measurements with a thread diameter of 0.112" and fully threaded configuration. Manufactured to Type 25/BT tapping screw standards with right-hand threading and 24 threads per inch specification. The screw demonstrates full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring adherence to international substance restriction requirements. Proper installation requires a No. 41 drill bit (0.096" diameter) for optimal thread engagement in plastic materials.
