صامولة لمسمار ذاتي الثقب 3.5 De Dietrich JJJ008380261

Self-tapping screws are commonly used in heating equipment to fasten components without the need for pre-tapped holes. This nut for self-tapping screw 3.5 is designed to be used with self-tapping screws of that size, providing a threaded anchor point in thin materials. It is often used in boiler casings or burner enclosures where a secure fastening is required. The nut ensures that the screw has a firm grip, preventing loosening due to vibration or thermal expansion. For boiler maintenance and repair, this nut is a handy component for creating reliable connections in sheet metal parts.
