Abstract

The invention discloses a self-tapping screw with a lubricating function, which relates to the technical field of self-tapping screws. The self-tapping screw aims to solve the problem that the laborand time are wasted during mounting due to that the existing self-tapping screws are unevenly lubricated. A drill bit is arranged at the lower end of the self-tapping screw rod; self-tapping threads are formed in the outer wall of the self-tapping screw rod; the self-tapping threads are integrated with the self-tapping screw rod; the self-tapping threads obliquely surround the self-tapping screw rod; a hexagonal flange head is arranged at the upper end of the self-tapping screw rod and fixedly connected with the self-tapping screw rod; a hexagonal head is arranged on the upper end face of thehexagonal flange head and fixedly connected with the hexagonal flange head; a tightening pad is arranged at the lower end of the hexagonal flange head; a lubricating oil inlet is formed on the front end face of the hexagonal head and integrated with the hexagonal head; a rubber plug is arranged inside the lubricating oil inlet; and the rubber plug is detachably connected with the lubricating oil inlet.

Description

technical field [0001] The invention relates to the technical field of self-tapping screws, in particular to a self-tapping screw with a lubricating function. Background technique [0002] Self-tapping screws, or quick-thread screws, are quick-fit fasteners made of steel with galvanized surface passivation. Self-tapping screws are mostly used for the connection between thin metal plates (steel plates, saw boards, etc.). When connecting, first Make threaded bottom holes for the connected parts, and then screw self-tapping screws into the threaded bottom holes of the connected parts. Self-tapping screws were introduced into industry in large quantities in 1914. The earliest design (basically imitating wood screws) was A thread-forming screw made of hardened steel with an A-shaped end, mainly used to connect sheet metal channels for heating and ventilation systems, so it is also called: "sheet metal screw", by the 1920s At the end, with the broadening of the market and new app...
