Self drilling Screw made of 410 stainless steel, high hardness (40 Rockwell C), steel process.
Drilling screw is also very strong hardness, compared to the ordinary screw up, not only to maintain the ability is good, the connection object effect is also very strong, for the performance of the screw, are generally does not need auxiliary processing, can be directly on the object directly drill a Kong Sue into objects, not just use rise very convenient, Also can greatly improve the efficiency of work. This kind of drilling screw can be said to be the first choice of workers in various fields.

The Central Silk Bureau of India also collaborated with the State Sericulture Bureau to launch a “catalytic development plan†to develop the silkworm and silk industry. According to the catalytic development plan, it provides incentives for the production of quality silk yarn. The Karnataka government also recommends extended support for better technology transfer for silkworm farmers to provide silk productivity and quality. The government also allows the import of modern automatic wire-wound machines and double-mesh wire-wound machines and their accessories with concession tariffs to reduce production costs, make the sericulture and wire-wrapping departments more competitive, and help silkworm farmers and entanglers.
