What is the tolerance range of precision screws?
The screw rod in the ordinary T-slot nut is cuboid, so the T-slot nut can only be inserted into the nut from the end face of the T-slot, which makes it impossible to quickly complete the installation of the T-nut, which is inconvenient to use. Usefulness is greatly limited.
flange T-bolt, comprising: a T-bolt including a threaded tooth body and a bolt head fixedly connected to the threaded tooth body; a flange gasket with a plurality of clip teeth, the flange gasket passing through the The plurality of clamping teeth are clamped with the bolt head of the T-bolt. The technical solution of the utility model is that when the groove-type embedded parts are embedded vertically or at a certain angle, the plastic flange of the new T-bolt will help the bolt to be pre-positioned at a certain position of the groove. When multiple T-bolts are used for fixing, Only one worker needs to pre-arrange the bolt positions and then lock the nuts, which greatly improves the construction efficiency.
Screw, some people call it screw (screw), screw (screw rod). In fact, the screw is a general term, and the screw and the screw rod are different from each other. Screws are generally called wood screws; they are the ones with a pointed end at the front and a larger pitch. They are generally used to fasten wooden and plastic parts. The screw rod is a machine screw (machine screw), which is the kind of flat head at the front end. The pitch is small and uniform. It is generally used to fasten metal and machine parts.
At present, it has become very common to use automated tools to hit screws. However, when the material of the fastening object is relatively soft, the screw fastening is often prone to skew, not sticking, and the screw hole is damaged during the fastening process. Metal shavings can also be created in the shards, which can short out the board.
