Professional Applications & Engineering Value

These 1/4"-20 UNC flanged hex head tapping screws are engineered to solve critical fastening challenges in industrial assembly operations. The 410 stainless steel construction provides excellent strength and corrosion resistance, while the thread cutting design creates precise mating threads in brass, cast iron, and sheet metal substrates without pre-tapping. The integrated flange distributes clamping force over a wider area, reducing material stress and preventing loosening under vibration. The external hex drive accommodates high torque applications, making these screws ideal for machinery, electrical enclosures, and metal fabrication where reliable, permanent fastening is essential. Their coarse thread spacing ensures quick installation and superior pull-out resistance in both soft and hard materials.

Specification Summary & Compliance

These tapping screws feature 1/4"-20 UNC coarse threads with Class 2A tolerance for consistent fit and performance. The fully threaded design and blunt tip facilitate precise thread cutting action. Manufactured to industry standards for thread cutting type F screws, they are designed for use with No. 1 drill bit (0.228" diameter) for proper hole preparation. The products are fully RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting stringent environmental regulations for industrial applications.
