Summary of information:We have more than ten years of production experience in the screw industry. The main products are: 4.8 grade iron washer...

Self-tapping screws, or quick-thread screws, are quick-release fasteners made of steel that are galvanized and passivated on the surface. Self-tapping screws are mostly used for the connection between thin metal plates (steel plates, saw plates, etc.). When connecting, first make a threaded bottom hole for the connected piece, and then screw the self-tapping screw into the threaded bottom hole of the connected piece.

T-bolts are a common type of bolts that tend to be used with rails when used. When the existing rail is in use, the T-shaped bolts are easily stuck and cannot reach the designated position well, and the use is not convenient enough, so that the T-shaped bolts cannot be well fixed.

The contact surface between the existing chassis and the main board is generally not a horizontal plane due to processing reasons, especially the main board is prone to warping deformation. It will increase, resulting in deformation of the motherboard and poor memory contact, affecting normal use.

At present, most of the thread locking structures use an integral nut and a matching external thread screw structure. To remove the nut from the screw rod, it must be completely unscrewed along the screw rod, which is time-consuming and labor-intensive. It is more inconvenient to install.

This clearance determines how much the bone fragment fixed by means of the locking screw in the corresponding locking hole can move relative to the nail and thus also relative to other bone fragments fixed by the same nail due to the rigidity of the nail. Together with the flexibility of the material and the overall device this can build up to a size that prevents or decisively delays effective healing. In order to ensure the applicability of the locking device to the surgeon, this gap, although unavoidable, is clinically undesirable in some indications (eg in the case of metaphyseal fragments). Even a screw with a full cross-section, which can have an internal thread in the locking hole, is not gapless. This internal thread only prevents possible axial movement of the screw on the locking screw.

We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: hexagon head screws, cabinet bolts, complete sets of external hexagon bolts, small outer diameter through-hole pressure riveting nuts and other products, we can provide you with suitable products Your fastener solution.
