Title: tapping threads Post by: Jonno on January 23, 2005, 11:51:40 AM Hi,
anyone ever tried to repair the rear of a grille when screws have been broken off in there? I've got the broken screws out (eventually...) but not sure what to do next. Do the threads need re-tapping or are the screws self-tapping (they have a wierd groove in 'em)? What are these things anyway...the parts catalogue calles them 'type G, no.10' Is this a BSP parallel thread? thanks Jonno ???

Just used ordinary threaded hex heads.

Are you talking about the die cast vertical and/or the two piece "eyebrow" sections? The new ones have a hole, no thread, and the bolts are tapered slightly at the end of the thread so that they cut a new thread as they are screwed in. Not sure of the thread size, however they are not a self tapper per say, however a self tapper replacement would work, especially if you have enlarged the hole.

The metal does seem pretty soft (unlike my screw extractor!) so I think Ill just try gently easing one back in. If it doesn't cut/hold I'll find something with slightly larger diameter.
thanks for the info. |
