Abstract

The invention relates to a novel fastener with threads. The fastener comprises an arc cap, a screwed connecting structure, and a chamfer. The arc cap is on the top end. A prism structure is arranged under the arc cap. The prism structure and the arc cap are casted integrally. The screwed connecting structure is casted under the prism structure. Secondary threads are arranged on the lower part of the prism structure.

Description

technical field [0001] The invention belongs to the field of manufacturing technology, and in particular relates to a novel fastener with threads. 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. Contents of the invention [0003] The present invention overcomes the deficiencies of the prior art and proposes a novel threaded fastener, which has exquisite structural design, unique craftsmanship, fine processing, energy saving, noise reduction, safety and environmental protection, and reduced labor intensity. [0004] The technical solution of the present invention is: a new type of threaded fastener, including an arc-shaped cap, a threaded connection structure and...
