Insert Nuts Type D M6 x 20mm Pack of 50
A real moneysaver
I needed to repair the weathered hardwood frame of the canopy of a garden seat. It had been manufactured with 13mm insert nuts which had loosened as the damp had got into the end grain. Browsing through the latest Screwfix catalogue - and not even knowing what they were called - I found these 20mm nuts. The perfect solution, they've made a robust repair - and with enough to spare for the next job.
A very satisfied customer.

Great - Use Type D not E
I really rate these fixings and use them for some quite large bits of furniture. I prefer the longer ones, with the flanged front, which is stronger than the "invisible" type (that's E type), which can split when being positioned in hardwood. They positions well, and with a dab of threadlock on the M6 bolt that goes in, a really secure and shakeproof fix is achieved, one that can be undone and re-fixed without any problem at all.
