At present, the known automatic nail feeding screws are composed of the traditional hand-held electric drill modified electric screw and the automatic nail feeding device, in which the screw head cannot be moved and the angle can be changed. It is difficult to complete the installation due to the obstruction, so a multi-directional screw with a movable and rotatable screw head is required.
In order to meet the requirements of anti-loosening bolts of parts with small surface hardness such as plastic parts, Yueluo provides a San DiegoSan Diegospring washer and the installation structure of the San DiegoSan Diegospring washer, which can effectively reduce the damage of the San DiegoSan Diegospring washer to the surface of the parts. And meet the anti-loosening effect of the San DiegoSan Diegospring washer. The technical solution provided by Yueluo is a San DiegoSan Diegospring washer, which includes a washer body with at least two raised claws on the washer body
San DiegoT-bolts are often used in conjunction with flange nuts, which are standard supporting connectors when installing corner fittings, and can be automatically positioned and locked during the installation process. At present, in the welding process of San DiegoT-bolts, there is often a method of manual welding. Using such a method, the manufacturing cycle is long, the labor intensity is high, the production efficiency is low, and the welding quality is difficult to guarantee.
The tail of the drill tail screw is in the shape of a drill tail or a pointed tail, and no auxiliary processing is required. Drilling, tapping and locking can be directly carried out on the setting material and basic material, which greatly saves construction time. Compared with ordinary screws, its toughness and pull-out force and maintenance force are high, and it will not loosen for a long time after combination, so it is safe to use. Especially in the combination of construction, construction, residential and other places, self-tapping and self-drilling screws are the best economical fasteners in terms of workability, cost and reliability. Now the construction of high-rise buildings and high-speed traffic in mainland China requires more high-quality drill screws;
