Description

technical field [0001] The invention belongs to the field of manufacturing technology, and in particular relates to a plug fastener. Background technique [0002] The current plugs have poor chemical resistance, are highly corroded by sewage and waste water, and are corroded by soil rotten substances. In the ultra-low temperature environment of minus 60°C, there are phenomena of freezing cracks, swelling and water leakage, and cannot adapt to different equipment specifications. Sex is poor. [0003] Contents of the invention [0004] The invention overcomes the deficiencies of the prior art, and proposes a screw plug fastener, which has exquisite structural design, unique technology, fine processing, energy saving, noise reduction, safety and environmental protection, and reduced labor intensity. [0005] The technical solution of the present invention is: a screw plug fastener, including an arc-shaped cap, a threaded connection structure and chamfers, the arc-shaped cap ...
