Professional Applications & Engineering Value

These M4.2 x 9.5mm tapping screws are engineered to address common challenges in metal and sheet metal assembly, where traditional fasteners may strip threads or require additional tapping steps. The 18-8 stainless steel material offers excellent resistance to oxidation and chemical exposure, ideal for outdoor equipment, automotive components, and electronic enclosures. With a thread cutting Type C design and pointed tip, these screws effortlessly form mating threads in pre-punched or drilled holes, reducing installation time and tool wear. The Phillips drive and oval head combine for a secure, low-profile finish that withstands vibration, making them a reliable choice for maintenance-free applications in manufacturing and construction sectors.
