Screw Sleeve Features:

The reason for the use of positive and negative wires for the steel bar connection sleeve is to prevent the heads connected elsewhere from being loosened or falling off.

2. The positive and negative wire sleeves are used in the position where the steel bar cannot be rotated, and can be connected by left and right screw connection sleeves. It requires that one end of the connecting sleeve and the steel wire head on the corresponding side are processed into left-handed threads. When connecting, the left- and right-handed thread connecting sleeves face the corresponding left- and right-handed thread heads, respectively. After rotating the sleeve, the steel bars on both sides will face the connecting sleeve. The middle is close and screwed to the top, so as to realize the convenient and quick connection.
