handy for travel toolkit
My brother keeps a pack of these solid wall inserts in his car trunk kit whenever we go on long road trips. The 5/16 inch internal and 7/16 external size worked well on our aluminum motor mount repair, though packaging box was slightly dented upon delivery. Still, the thread locking adhesive set quickly and saved our journey.
