• Enhanced drive stability provided by the Phillips No. 2 drive, reducing cam-out and ensuring secure, consistent fastening.
• Optimal material displacement from coarse UNC threading, delivering superior holding power and vibration resistance in demanding applications.
• Reliable full-thread engagement along the entire 1/2" length, maximizing pull-out strength and fastening integrity.
• Broad material compatibility for use in brass, cast iron, and sheet metal, simplifying inventory for diverse industrial projects.
• Compliance with global environmental standards including RoHS 3 and REACH, ensuring safe and sustainable use in regulated markets.

Professional Applications & Engineering Value

These 8-32 UNC thread cutting screws are engineered to address common industrial fastening challenges, such as the need for reliable thread formation in brittle or thin materials. The Type F tapping screw design with a blunt tip and coarse thread spacing efficiently cuts precise mating threads in brass, cast iron, and sheet metal, reducing installation time and preventing material cracking or stripping. Manufactured from 410 stainless steel, these screws offer excellent resistance to oxidation and corrosion, making them suitable for outdoor, marine, or high-moisture environments. The combination of a Phillips drive and pan head provides a low-profile, secure fastening solution that withstands vibrational forces, ensuring long-term joint integrity in machinery, enclosures, and structural assemblies.

Specification Summary & Compliance

This screw features a No. 8-32 UNC coarse thread with a diameter of 0.164" and a length of 1/2", conforming to standard UNC thread specifications for consistent fit and performance. The fully threaded shank and standard pan head with a 0.322" diameter and 0.115" height ensure uniform clamping force. It is designed for use with a No. 29 drill bit (0.136" diameter) for optimal thread engagement. The product is manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming adherence to environmental and safety standards for industrial components.
