Technical Information 插销螺套技术信息
The key-locking threaded inserts are ideal for thread reinforcement,especially when the mating stud or bolt will be removed frequently。They provide strong,permanent steel threads in a weaker parent material — ferrous, non-ferrous, or non-metallic。Key Inserts are also well suited for quick repair of stripped,damaged,or worn threads。 A solid version is also available to use as a handy plug to relocate holes drilled or tapped on the wrong location。 Install with standard drills and taps。Important:Use tap drill specified in table (slightly larger than standard for that thread size)。 Tap-drill hole tolerance should be -.001/+.004 (-.001/+.005 above .500 dia)
插销式螺纹套对螺纹加固是很理想的,特别是在需要经常拆卸的双头螺柱或螺栓。它能在较软的母体材料上(铁、非铁或非金属)提供强固的永久的螺纹连接。这种螺纹套也能很好的用于条带状、损坏的或磨损的螺纹。当孔钻错位置时,还可以用实心的螺纹套把它堵住。其安装时用标准的钻头和丝锥安装。重要:用表中指定的钻头和丝锥(比标准的螺纹尺寸稍微大一点)。 钻孔的公差应当在-0.0254mm到+0.1016mm(大于500时-0.0254mm-+0.127mm)。
Locking keys are driven down into the parent material during installation, providing a positive mechanical lock against rotation. Inserts with an ID thread 5/16 and above have four locking keys, smaller sizes have two。
